Technical Proposal 1 Distribution Automation Overview

1 Distribution Automation Overview

1.1 Distribution Automation Definition

Power Distribution

Power distribution is a phase between the power transmission and power

consumption. During power transmission, electric power is transmitted over a power

distribution network to user clusters. That is, the power distribution network is responsible for

distributing power in the electric power system.

A power distribution network features wide coverage, various technologies and

implementation methods, complex equipment location environments, and long-term and

difficult system construction. Gradually, distribution automation (DA) is introduced as a new

concept, intended to improve the control and management capabilities during power

distribution and finally to reduce line loss and meet users' power consumption experience

requirements.

A power distribution network consists of substation, power distribution station, distribution

transformer, secondary substation, lines of various levels, direct power distribution lines from

the power plant, lines to the user end, and power consuming equipment.

Distribution Automation

Based on electrical equipment and modern electronic, communications, computer, and

network technologies, DA integrates monitoring, protection, control, accounting, and work

management over the power supply department, increasing power supply quality, improving

user relationship, meeting various user requirements at more reasonable prices, and thereby

achieving economical power supply and better enterprise management.

DA is a huge, complex, comprehensive, and systematic system, including all functional data

flows and control related to the power distribution system of an electric power company. It

enhances cooperation between isolated power distribution grids, thereby optimizing the power

distribution system. This is also one of the main current smart grid theories. DA functions as

a whole for increasing power supply quality, improving service level, and reducing operating

costs.

In a broad sense, a DA system includes primary power distribution devices, secondary

collection and control devices, and management platform.

In a narrow sense, for protection, measurement, control, and communications device vendors,

the DA system is a secondary collection, control, and management system, including the

power DA master station system (DMS), DA communications system, power distribution

smart terminal (xTU), other intelligent devices, and auxiliary systems.

1.2 Distribution Automation Values

Major Problems with Power Distribution Grids During the power distribution, the power voltage is low and large line loss occurs during

power transmission, which fail to meet energy-saving and environment-protection requirements in the new era.

The automation level is low, self-healing from a fault is weak, fault diagnosis is difficult,

and fault recovery time is long, which affect social production and result in poor power consumption experience.

As a key part of a smart grid, the DA project is intended to reduce power waste, increase

power supply quality, and improve power consumption experience. A mature DA

system will significantly increase power service capabilities.

Distribution Automation Values for the Power Distribution System Increases power supply reliability.

Optimizes the power flow trend structure, restricts the fault section, minimizes the power

failure range, and quickly provides feedbacks on fault information, which help reduce patrol time, quicken fault recovery, and ensure reliable power supply.

Improves user experience.

Increases the power quality, shortens the outage time, restricts the outage range, and therefore brings better power consumption experience.

Decreases fault costs.

Intelligent data collection and remote control allow for immediate fault feedback and

handling and thereby reduce the costs for manual fault checks.

Enriches power types.

Smart Grid calls for small power supplies and distributed power access. DA prepares a network basis for distributed power access to the power grid.

Reduces power loss.

Power flow trend optimization helps restrict the fault range, balance trend allocation, and reduce power loss.

Technical Proposal 2 Customer Requirements

2 Customer Requirements

2.1 General Requirements

As the conflict between the fast growth in the power load and the current power grid

conditions becomes gradually sharper, real-time and intelligent monitoring over primary lines,

load, and line loss is required. Due to aged lines and non-standard power distribution grid

planning, line faults increase and fault fail to be located in time. In such a case, DA is required,

allowing for monitoring over primary distribution grids based on the supervisory control and

data acquisition (SCADA) system.

DA is intended to help improve power supply reliability, increase the power quality and power

grid operating efficiency, and meet customer requirements. It should be achieved with

different phases and steps based on local area power grid conditions.

A DA system needs to be constructed for power dispatching and production commanding on

the power distribution grid. It is responsible for monitoring and controlling the power

distribution grid, and achieving information exchange, sharing between related application

systems, and meeting comprehensive application requirements.

Construction of a power distribution communications network needs to be centered on

meeting requirements for power distribution grid automation, communications of the

marketing system, video surveillance system, and users. Its main part should be a private

network, and can be supplemented by a public network; its main communications should

be wired communications and can be supplemented by wireless communications.

The power distribution communications network can use a private network or public network.

The communication channels between the power distribution master station and the power

distribution sub-station form the backbone layer communications network. The

communication channels between the power distribution master station/sub-station and the

power distribution terminals form the access layer communications network.

Generally, the backbone layer communications network should be an optical fiber

transmission network; when conditions are not met, it can be a combination of an optical

fiber network plus supplementary other types of private network communications. The

backbone layer communications network should provide alternative routing capability

and high survivability.

The access layer communications network can be a combination of fiber private network

and other types of communications such as power line carrier (PLC) and wireless

communications. When using multiple communications types, the access layer

communications network needs to provide unified access, port specifications, and management and provide Ethernet and standard serial communication ports.

Video surveillance in DA: The video surveillance window of the camera needs to be

embedded in the SCADA interface and the interface needs to allow for remote control over

the camera. Electric power information needs to be added to the camera video

surveillance window. Upon the detection of alarms or key operations, video surveillance

automatically triggers corresponding actions including pointing the camera to the alarming

point direction, label the camera video for future queries, and starting video recording. Upon

an alarm, the SCADA needs to display real-time video window of cameras around the

alarming point, allowing the user to check the onsite conditions in real-time manner.

2.2 Communications Network Requirements

2.2.1 Distribution Automation Communications

A DA communications network is the nerve for the DA system, responsible for transferring

measurement and control information, feeding back fault status, and carrying various electric

power related services.

By access type, a DA communications network is classified to two types: wireless access

and wired access. Table 2-1 lists the wireless and wired access technologies.

Table 2-1 Classification by access media type

Classification Technology

Wired access Power line carrier (PLC)

Industry Ethernet

Field bus (RS232/485)

Audio private line (PCM)

Passive optical network (EPON/GPON)

Wireless access 230 MHz microwave dedicated communications

Public network GPRS/CDMA/EDGE

Wireless private network (LTE)

With rapid increase in the number of power distribution terminals and development of service

of metering and video surveillance, there are higher requirements on communications

capabilities. However, most power grid communications methods have bandwidth and rate

limits, which restrict DA construction and development of electric power functions.

Mature fiber and wireless private network communications technologies have gradually been

applied in power distribution communications networks.

2.2.2 Access Network

A distribution terminal communications access network, namely, the communications network

from the substation to the distribution terminal, should be constructed with various types of

communications methods: fiber private network, PLC, wireless public network, and wireless private network.

PDA Solution

An electric power system involves various aspects and requests higher security. In this sense,

a DA communications network needs to meet more KPIs than other industry applications.

When convenient fiber cable layout conditions are available, prefer fiber private network

communications to construct the terminal communications access network. Prefer passive

optical network technologies. If fiber cable layout conditions are not met, for example, in old

cities with dense population, prefer a wireless private network such as the LTE technology.

Construction of a DA communications network has the following characteristics:

Network reliability

The DA communications network should be reliable. An electric power system requests

24-hour constant monitoring and control over distribution terminals, quick fault locating

and self-healing, certain redundancy, and powerful protection against disasters, lightning, and interference.

Data transmission security

The control, measurement, indication services of DA in the electric power system

determine the secure operating of the entire power grid and personnel lives and

properties, for example, switch control and power energy measurement. The DA

communications network should prevent DA communications services from illegal

access.

Real-time power services

Between terminals in an electric power system, highly real-time communication is

required between the power distribution master station and distribution terminals. Therefore, the real-time performance of data services is a KPI for DA communications.

Network device compatibility

A DA communications network consists of various network elements. Cooperation

between different communications standards, different NEs, and NEs from different

vendors is available only if the NEs are compatible with each other, and support various NE combinations and service requirements.

Flexibility of network planning

To meet various user requirements, the DA communications solution should be

applicable to the actual site environments and actual platform and provide rich access

types to support different combinations. To allow for possible future reconstruction or

upgrades, terminals should support flexible expansion and network structure adjustments.

Reasonability of operating costs

Select proper technologies and networking modes based on the actual project site

environments and customer requirements. With customer requirements met, minimize

the customer network operating costs and maintenance costs.

2.2.3 Transport Network

A power communications network is constructed to ensure the stable and secure operating of

an electric power system. The power communications network, secure and stabile control

system, and dispatching automation system are called the three pillars for ensuring stable and

secure operating of the electric power system. Therefore, the power communications network

must be very reliable.

During operating of an electric power system, massive data needs to be transported between

power distribution centers in different areas, for example, power distribution data needs to be

backed up remotely. Therefore, a highly reliable and future bandwidth-oriented backbone transport network needs to be constructed.

According to the existing bandwidth prediction methods, data service bandwidths are

predicted to have an integer multiple increase based on the key power grid development trend,

its time sequence, and historical power grid service bandwidth requirements. This is not

applicable to this DA solution and will not be detailed in this document).

2.3 Environment Monitoring

2.3.1 Functional Requirements

Environment monitoring includes video surveillance, humidity/temperature

surveillance, water level monitoring, and fog/smoke monitoring.

DA environment monitoring is mainly deployed at substations, middle voltage switching

stations, and distribution room that are important to DA. After interconnecting with the power

automation system and power secure system, it can achieve remote monitoring over power

devices and their environment and therefore improve the system management level.

Figure 2-1 Environment monitoring service requirements

Based on the DA service requirements, the following environment monitoring functions are

required:

Real-time video monitoring and control: Monitors the site conditions and the device operating status.

Video recording: Displays, captures, stores, achieving, playbacks multiple videos of

selected cameras in each distribution room and middle voltage switching station. When a sensor product reports an alarm, cameras can start their video recording function.

Remote control: Remotely controls monitoring equipments devices (including cameras

and lights) at the station terminal. Turns on the lights immediately after an alarm is generated, and triggers cameras to start video recording.

Action with alarms: After an alarm is generated, triggers corresponding cameras or

camera presets if any so that video processing units or digital cameras in the power

distribution room and switching stations can automatically save and record videos; transmits alarm information and related images, notifies of the alarming position and

type on the geographic map; triggers other related devices, such as site lights and alerting

and ensures that the devices will automatically shut down after a preset time period;

triggers multiple cameras and other devices upon an alarm. The video processing unit can perform self-check on and reports alarms upon a fault on intra-station cameras.

Touring at a monitoring point: Provides automatic video touring at system monitoring

points; allows monitored objects to be specified as required, including videos in different

distribution rooms or middle voltage switching stations, different cameras in a same

distribution room or middle voltage switching station, and different camera presets of a

camera; allows the touring interval to be specified as required; supports automatic resets of the cameras performing touring.

Electronic map: The electronic map provides video browsing, device control, and alarm display functions.

Voice intercom: This function is mainly used to prevent misoperations, with monitoring personnel or high-level engineers supervising the site operations.

Onsite environment monitoring, including monitoring over temperature, humidity, water

leakage, smoke, and fog.

2.3.2 Deployment Requirements for Video Surveillance

Bidding for DA video surveillance is classified into separate bidding in a region or city and

unified bidding by a provincial company. For separate bidding, centralized deployment is

generally used. For unified bidding, distributed deployment is used.

Centralized deployment: The DA video surveillance platform is centrally deployed in a region

or city/county, and the surveillance peripheral units of distribution rooms or middle voltage

switching station are directly accessed to the system. Based on the conditions in region XX,

there are about 100 to 200 distribution rooms/middle voltage switching rooms. Assumed that

each distribution room/middle voltage switching station has three to four cameras, access of 0

to 3000 cameras are recommended in centralized deployment.

Distributed deployment: The DA video surveillance platform has a distributed structure

partitioned to different layers and different regions, and consists of the DA video and

environment monitoring provincial master station system, distribution room/middle voltage

switching station video and environment monitoring regional master station system, and

distribution room/middle voltage switching station video and environment monitoring

terminal system. In distributed deployment, access of more than 3000 cameras is

recommended.

Compared with centralized deployment, construction of a regional master station monitoring

subcenter is added in distributed deployment and therefore the system capacity is larger. The

following descriptions focus on the DA video surveillance monitoring platform and the DA

video monitoring terminals, where the DA video surveillance monitoring platform contains

the regional master station monitoring subcenter.

3.1 Solution Description

Based on modern communications technologies, electronic technologies, computer

technologies, and network technologies, DA integrates distribution grid data, demand-side

data, real-time online data, offline data, distribution grid structure, and geographic map to

form a complete automatic system, therefore achieving secure and stable operating of the

power distribution system and modernizing real-time fault monitoring, in-time protection,

effective control, and proper demand-side system management.

DA is aimed to increase power supply reliability, power quality, service quality, technological

management level, maximize the company benefits, and therefore to achieve win-win on the

power supply side and the demand side.

Figure 3-1 DA system architecture

3.2 Design Principles According to the system engineering design theories, the DA system is consistently

planned as a whole, with both centralized and distributed deployment used to ensure

sufficient data resource sharing and proper allocation of data and function settings (by

department such as power consumption or power distribution department, and by

geographic information). This finally helps improve the entire system performance,

prevent isolated island automation, and ensure data consistency with one unified power grid description database, and maximize the benefits on investments.

The software system and the hardware system use layered architectures to ensure system

maintainability, scalability, and applicability, prevent bottleneck effects, and ensure

adaptation to future distribution grid planning, proper stability, and future-orientation.

The system design complies various international standards to ensure the system openness and compatibility.

All applications (subsystems) in a DA system need support from the geographic

information system. In this solution, a high-performance geographic information system

is used as the unified support platform for the entire system, instead of an independent

distribution grid geographic information system. This enables all subsystems of the DMS

including SCADA to be constructed based on the same geographic information platform and to share non-graphic data, graphic data, and uniform map information.

The system hardware uses redundancy designs including a dual-microcomputer,

dual-communications network, dual-power supply, dual-channel access designs. The

redundancy designs ensures automatically switching upon a fault and constantly reliable

system operating. The operating system and database meet CZ-level security, and the

system meets strict security requirements corresponding to different operating levels of the system design.

The layered and distributed system architecture allows functions of the DA system to be

implemented by phase and stage based on the actual power grid development and social requirements, therefore providing high system flexibility and compatibility.

3.3 General View

Since a power distribution grid is allocated across different geographic places, its devices are

of various types, huge amount, and its network structure is complex, the DA solution uses a

vertically layered design to:

Prevent information transmission bottleneck effects.

Properly allocate functions on different layers, therefore reducing system complexity and improving system reliability and entire performance.

Ensure system maintainability and scalability to meet requirements for long-term system development requirements.

Master Station System Layer

The master station is the highest layer in the entire system, performs monitoring and control

over the power distribution grid, analyzes the operating status of the entire power distribution

grid, and therefore help coordinate power distribution sub-grids, achieve effective monitoring

and management of the entire power distribution grid, and ensure an optimal operating status

of the power distribution system. The master station is the core of the entire power

distribution grid monitoring and management system. As the man-machine

interchange window, it provides various functions such as graphic displays, system

maintenance, device management, reporting printing, and exchange with other systems, and

control and adjustments on controllable devices (including the power distribution

management system).

Communication Layer

The DA communication layer is the nerve of the DA system. Collection of power distribution

grid operating data, change of the grid operating status, and optimization of the power

distribution grid are all based on the communication layer. The communication layer consists

of the network layer and communication terminal layer.

Power Terminal Layer

The power terminal layer is the basic layer in the entire system. It collects, processes, and

monitors field information of column switch, ring main unit, pad mounted transformer, and

middle voltage switching station.

dual-screen workstation can be configured.

The maintenance workstation is for daily maintenance by maintenance personnel.

The reporting workstation is used for making and processing various reportings.

The distribution and dispatching workstation is used by distribution and dispatching

personnel for dispatching management, including making the maintenance plan, work-order ticket, and operation ticket.

The core backbone switch is used on the system backbone network to achieve inter-node

effective communication.

5.1 Overall Communication Solution The power distribution communication network is an important part of DA and is a basis for

smart grid. A smart power distribution communication network is expected to use economical

and advanced communication technologies to meet requirements in various smart power

distribution grid development stages. It should support flexible access of various types of

services and provide plug-and-play power communication. It provides information exchange

and communication channels for power consumers and distributed power. The distribution

grid communication mainly uses three technologies: optical communication, wireless

communication, and low-voltage PLC communication, and provides secure and reliable

communication measures for smart power distribution grid monitoring, control, and user

interaction.

Different types of services on the smart power distribution communication network have

different coverages and require different communication channels. Therefore, they need

special analysis attention and will function as basis for selecting a proper technology and

solution for the distribution communication network.

Figure 5-1 Solution overview

The communication network provides the communication highway between the DA devices

and the DA master station, and implements four remote functions: measurement, indication, control, and remote adjustment. It mainly completes bidirectional DA data transfer.

Sending monitoring data upwards: sends the monitoring data from various monitoring

devices in the power infrastructures such as the ring main unit, switching station, and column switch to the master station or sub-station system, in time.

Delivering configuration data: Delivers the configuration data in the master station or

sub-station system to the various monitoring devices in the power infrastructures such as

the ring main unit, switching station, and column switch, in real-time manner.

The passive optical network (xPON) is the main optical communication technology

used, wherein EPON is the currently most mature, cost-effective, and widest-applied. The

LTE solution is the recommended wireless communication solution. Its flattened network

architecture helps simplify the distribution grid, reduce distribution grid management costs,

and reduce the network operating complexity. In addition, its high data transmission

performance and network capacity can significantly improve the performance of the access

layer communication system supporting the user information collection system and further

improve the intelligent capabilities of the distribution grid.

reliability for information transfer. They have passed China's national admission test for the

electric power industry and met the national electric industry's all standards and requirements.

They have been certified by China's Ministry of Industry and Information Technology (MIIT),

European Telecommunications Standards Institute (ETSI), and Network Equipment-Building

System (NEBS).

Figure 5-2 xPON communication topology for DA

Network devices for DA mainly consist of OLTs at the sub-station communication layer and

ODN devices as well as ONUs at the access communication layer.

Sub-station communication layer

An OLT is installed at a power transformation sub-station. In the upstream direction, the

OLT is connected to the existing transport network on the live power communications

network. Meanwhile, the OLT has the capability for independently supporting ring

networks (RSTP/MSTP). When a link to a node fails, the OLT is able to switch over

services from the faulty link to another uplink rapidly. The OLT provides GE interfaces

and will provide 10GE interfaces for upstream transmission according to the requirements for bandwidth.

Access communication layer

The access communication layer mainly consists of ODN devices and ONUs. The ODN

is an optical distribution network between the OLT and ONUs, responsible for

transmitting monitoring data collected by ONUs from FTUs/RTUs/TTUs to the OLT at

the sub-station communication layer, or transmitting information about dispatching and

settings of sub-stations or the master station to FTUs/RTUs/TTUs through ONUs to

control these terminals. Optical splitters on the ODN are flexibly configured according to

hub-and-spoke, daisy chain, and ring topologies commonly used for power distribution

networks. Accordingly, different split ratios are available for different nodes. ONUs are

installed at switching stations, in ring main units, and on pole mounted switches for

collecting monitoring data from FTUs/RTUs/TTUs. An ONU provides two upstream

PON ports. When one PON port fails, the other port can take over quickly. The ONU

provides FE ports for downstream transmission.

Sufficient optical power budget must be available for a new network according to the

allowable attenuation for the path between the OLT and the ONU, ONU configurations,

actual conditions of the power distribution network, and future network expansion,

reconstruction, and upgrade. Therefore, the following must be considered for network construction:

PDA Solution




21

When the number of network nodes exceeds the number of ONUs and optical splitters,

the network should be split. New optical fiber cores are added to decrease the levels of optical splitters and the path attenuation.

Optical splitters are connected to optical fibers by soldering in most situations. The loose

joints should be reduced to a minimum to reduce possibility of damages to and faults on

links.

Movable connectors can be used or an optical splitter can be pre-installed to provide branch interfaces at locations with potential capacity expansion in the future.

5.2.2 Network Design

Design of the xPON Network Topology for Distribution Automation

A DA network is usually in hub-and-spoke, daisy chain, or ring topology. In a DA network,

the PON network topology, levels of optical splitters, and split ratios depend on the actual

network conditions.

Theoretically, the levels of optical splitters are not limited for a PON system. However, the

optical attenuation for each ONU must be less than 28 dB. Actually, the more the levels of

optical splitters, the less the trunk fibers used. However, coupling loss increases and the

network topology is more complicated meanwhile. Therefore, the network topology design

must be optimized based on optical fibers available. The following describes the three

common topologies.

Hub-and-Spoke

The hub-and-spoke topology is applicable to an optical fiber communication network for a

power distribution network whose main line adopts the single power source hub-and-spoke

topology. ONUs with two PON ports are used in the hub-and-spoke topology for collecting

information from terminals, and reserving space for changing the topology to daisy chain after

capacity expansion.

The optical power budget must be reserved when planning the network because the

topology will finally change to daisy chain in consideration of network expansion,

reconstruction, and upgrade in the future. At the preliminary stage, each PON port on an OLT

supports up to eight ONUs. When the topology finally changes to daisy chain, each PON port

on an OLT supports up to 12 ONUs.

Figure 5-3 Hub-and-spoke topology

Daisy Chain

The daisy chain topology is applicable to a communication network for a power distribution

network whose main line in the target region adopts the daisy chain topology. The

PDA Solution




22

communication network is of a double-chain topology, where two 1:2 uneven optical splitters

are used for each access point. Each ONU is connected to two OLTs at substations at both

ends of the line. Therefore, bi-directional dual-PON port protection and hot standby as well as

cold standby are available to ensure self-healing protection for the entire network. As a result,

the network is secure and reliable.

Certain optical power budget must be reserved because the topology may change in

consideration of network expansion, reconstruction, and upgrade in the future. Finally, each

PON port on an OLT can support up to 16 ONUs.

Figure 5-4 Daisy chain topology

Ring

The ring topology is applicable to a communication network for a power distribution

network whose main line is of a ring topology and communication network is also of a ring

topology. In a ring topology, an ONU is connected to different PON ports on the same

substation's OLT through optical fibers to ensure self-healing protection for the entire

network.

Figure 5-5 Ring topology

PDA Solution




23

Among the three topologies, the daisy chain has two OLTs, each at one substation, to connect

to each ONU and therefore offers bi-directional dual-PON port protection and hot standby

as well as cold standby to ensure self-healing protection for the entire network. As a result, the

network is secure and reliable. Therefore, daisy chain is highly recommended for a DA

network.

Reliability of the xPON Network for Distribution Automation

A communication system for DA must be secure, reliable, and capable of protecting services.

The PON technology provides a variety of link protection schemes. In such a scheme, when

an optical link fails, the data on the link can be switched over to another link to improve

system reliability. Type A, B, C, and D are four common protection modes for a PON

network.

Type A: redundancy protection for trunk fibers

Active and standby optical fibers are used. When the active optical fiber fails, its

services will be switched over to the standby optical fiber manually. During the manual

switch over, the services are interrupted.

Figure 5-6 Redundancy protection for trunk fibers

Type B: OLT's dual-PON port redundancy protection

When the trunk fiber fails, the services under the active PON port can be switched over

to the standby PON port automatically. However, this type of protection is unavailable against faults on the ODN or ONUs.

Figure 5-7 OLT's dual-PON port redundancy protection

PDA Solution




24

Type C: ONU's dual-PON port full protection

In this protection mode, the OLT's standby PON port is in the cold standby state, and the

ONU's standby optical module is also in the cold standby state.

Figure 5-8 ONU's dual-PON port full protection

Type D: ONU's dual-PON port full protection 2

In this protection mode, the OLT's active and standby PON ports are in the working state,

and the ONU's active and standby optical modules are also in the working state.

Figure 5-9 ONU's dual-PON port full protection 2

Type C and D protection mechanisms ensure link reliability and are suitable for distribution

networks.

The optical distribution network (ODN) in an xPON network is passive. Therefore, the ODN

is highly secure because only physical faults can occur on the ODN. The OLT is usually

installed at a substation's communication equipment room in good conditions, so the OLT is

easy to maintain. ONUs are installed in different locations, some of which are in harsh

environments. So, the possibility of failure on ONUs is comparatively high. However, when

an ONU fails, only the terminals under the ONU are affected.

A communication system for DA covers a large number of terminals. That is, up to dozens of

terminals are connected to each PON port. This requires that a communication system is

capable of link protection and anti-single-point/multi-point failure. According to the preceding

xPON topologies, an ONU is connected to an optical splitter through a feeder fiber. When a

PDA Solution




25

feeder fiber or an ONU fails, only the communication of this feeder fiber or ONU is affected,

so the communication link is capable of anti-single-point/multi-point failure. Meanwhile, an

ONU is connected to different OLTs or an OLT's different service boards through dual PON

ports, which ensures link protection for the entire communication network.

Link Power Budget Calculation

Link power budget calculation is a key point for designing an ODN , which indicates whether

the link design is reasonable. The power budget range for a PON technology must be

considered first regardless of which PON technology is used. For example, the theoretical

power budget for GPON ranges from 13 dB to 28.5 dB. In a link deployment, the ODN's link

loss must be within this range, and otherwise the services cannot be normally transmitted on

the link. In an actual deployment, at least 1 dB margin must be reserved.

When calculating link power budget, consider adequately splice loss of various joints such as

soldered joints and loose joints, optical fiber loss, and loss of uneven optical splitters. Table

5-1 lists the criteria for link attenuation and the values of nominal parameters commonly used

in link power budget calculation.

The following describes how to calculate link power budget by taking a daisy chain topology

as an example. The link contains eight nodes from A to G. The distance between neighboring

nodes is K1 to K8 respectively. The worst value calculation method is used to analyze the

attenuation of each node at the optical link.

Use the following formulas to calculate optical attenuation:

the worst value among these values meets the attenuation criteria for links at different classes.

secondary power devices such as FTU/DTU/TTU, master station, and sub-station. In actual

deployment, the base station can be located at the power supply bureau or the substation,

since they belong to the power company and can ensure transmission and power supply; the

CPEs are located at nearest places such the switching station or the ring main unit, and provide FE interfaces or RS serial interfaces for connections to devices such as

FTU/TTU/DTU according to IEC 60870-104 or 101, and therefore support bidirectional

transfer of collection and control data.

Figure 5-12 Network design procedure

LTE Base Station Planning Guidelines Site selection guidelines

To ensure long-term stable operating of base stations, select the site for the base station

equipment room based on communications network planning requirements,

communications technological requirements, and hydrological, geographical, and transportation requirements. The general site selection guidelines are as follows:

− Avoid environments with high temperature, dust, toxic gases, explosive materials,

and unstable voltage.

− Avoid areas that are subject to earthquakes or loud noise.

− Select a site far away from industrial boilers and heating boilers.

− Select a site far away from high-power radio station, radar station, or other

interference sources, and ensure that the interference field strength is within the base stations' specifications for shielding useless radiation.

− Select a site at least 3.7 kilometers away from the seaside or salt lakes. If this

situation is unavoidable, the equipment room should be airtight and equipped with air

conditioners. In addition, the salt-affected soil cannot be used as construction materials. Otherwise, use devices that are protected against poor environment.

PDA Solution




30

− Select a site far away from pollution sources.

− At least 5 kilometers away from heavy pollution sources such as smelteries and

coal mines.

− At least 3.7 kilometers away from medium pollution sources such as chemical, rubber, and galvanization industries.

− At least 2 kilometers away from light pollution sources such as packinghouses and tanyards.

− If it is impossible to keep the equipment room away from pollution sources, the

equipment room should be constructed upwind of pollution sources.

− Keep the air vent of the telecom equipment away from exhausts of urban wastes, big

cesspools, and sewage treatment tanks. Keep the equipment in the positive pressure

state to prevent corrosive gases from damaging components and circuit boards inside the equipment.

− Do not construct the equipment room either in a room for feeding poultry or in an

unused chemical fertilizer warehouse. Ensure that the equipment room is located

away from livestock farms. If this is impossible, keep the equipment room upwind of the livestock farm.

− Select a site away from roadsides or quarries, where the air is dense with dust.

It is recommended that the equipment room be located on the second floor or higher. If

this is impossible, the site must be located at least 600 mm above the record flood level.

If the preceding requirements cannot be met, assess the base stations' adaptability to the

specific environment or add corresponding protection measures to ensure stable and secure operating of the base stations.

Network estimation

Network assessment includes simple analysis of a future network, estimates the network

size based on related input information, predicts the network construction scale

(approximate number of base stations, and base station configurations), and predicts the network construction period, costs, and manpower consumption.

During network estimation, you need to first learn about key network information,

including target coverage areas, target continuous coverage service requirements, and

estimate the required services and bearers, service quality requirements, and propagation

model. The more comprehensive and accurate the information collected during network

estimation, the more accurate the network size predicted based on the collected information.

Coverage planning

Different coverage quality designs result in different network estimations. For a good

system, its link budgets should be correctly prepared early during the design phase. The

link budget refers to the allowed maximum propagation loss calculated in difference

scenarios with the same communication quality. The link budget helps compute the

corresponding cell radius. The link budget should allow a balance between backward

signals and forward signals to be achieved. Determine the number of base stations and

their layout based on the actual network conditions and geographic environments.

Capacity planning

During capacity planning, you need to set up a proper traffic profile to describe users'

basic behaviors in a specific area. The traffic profile directly affects system resource

configurations and will finally affect the network construction costs. Different traffic

profiles need to be created for different types of services to reflect their resource

occupation data, since they have different characteristics. Plan the network capacity configurations based on the traffic profile and the network capacity requirements.

PDA Solution




31

During network planning, to ensure high reliability of DA communication, coverage and

anti-interference insurance takes precedence over capacity insurance in the initial network construction solution.

Antenna design guidelines

− Antenna height:

The antenna height design should ensure proper coverage and interference control.

The average building height within the coverage area can be used as reference during

antenna height planning, and different antennas at a same base stations can have

different height due to installation space restrictions in certain directions or planning

requirements to meet coverage, isolation, diversity, and anti-interference requirements in the certain areas.

− Antenna azimuth:

The antenna azimuth design should ensure even coverage over the entire network,

minimizing coverage space, minimizing coverage overlap, and avoiding complex

network planning due to later area splitting. The antenna azimuth is determined at the

pre-planning phase. During the site survey phase, adjust the azimuth of each sector

based on the obstacle information around the site to avoid signal propagation from being blocked or affected due to the obstacles.

Frequency planning

Proper frequency planning can improve network quality, reduce intra-system interference,

and provide users better network experience. The general frequency planning guidelines

are as follows:

Generally, frequency planning is conducted by cluster and area, to ensure similar

frequency reuse possibilities. During frequency planning, avoid opposite intra-frequency

sectors, which will cause severe signal interference in areas with overlapping coverage.

If multi-carrier capacity expansion is required on a network, the expansion can be

smooth only if it is considered during planning at the initial network construction phase.

Link budget planning guidelines

The link budget calculation approximately calculates the allowed maximum space link

loss between base stations and terminals, namely, summing-up and deduction of a series

loss on the uplink and downlink between the base stations and terminals, gains, and

parameters. Determine the average base station sector coverage radius and area

according to the calculated maximum link loss value, the propagation model, and the terrain type.

Based on the cell radius and the coverage range, you can calculate the minimum number

of base stations for meeting the coverage requirements according to the area formula. In

theory, an LTE system can cover a several-kilometers radius. However, in actual

application scenarios, factors such as the transmission rate and building blocking need to be considered.

Door Status Sensor

Door status sensors are installed at switching stations. Upon personnel entrance, a door status

sensor will generate an alarm to notify the master station on-duty personnel and trigger the

interlocked cameras to starting recording videos. This allows real-time information about

personnel entrance to or exit from the switching station to be recorded and reported.

Remote Light Control

Some switching stations are located in basements, where light conditions are poor and there is

almost no light at night. To ensure sufficient lighting, a light control system needs to be

installed at each switching station. Light must be remotely turned on before personnel check

field videos or images at the monitoring center, and must be remotely turned off after the

check. Therefore, the light control system must support the following functions:

Remotely turns on or off light at any time.

Turns on or off light as scheduled.

Upon an alarm, triggers the interlocked dome cameras to start recording and the interlocked lights to turn on.

Flood Alerting

Real-time monitoring over the water in the cable trench needs to be supported, and alarm

information needs to be generated when the water exceeds the alerting level. A water

detection and alerting system is installed in each switching station, providing the following

functions:

When the water level in the cable trench and the ground water level reaches 5 cm,

triggers audible and visual alarms to be generated at station terminals.

Sends real-time water alarm information to the monitoring center so that the

monitoring workstation screen at the center displays the images and videos in the alarming distribution room, and generates audible alarm indications.

Smoke Sensor

Highly-sensitive smoke sensors are installed in switching stations. Once the smoke

concentration in a switching station exceeds the altering level, its smoke sensor will generate

alerting sound and notifies on-duty dispatching personnel through the video surveillance

system so that they can assign personnel in time to visit the site and minimize loss.

IP Voice Intercom

Due to signal shielding, communication by means of mobile phones cannot work at some

switching stations, and therefore a bidirectional voice intercom system needs to be installed to

provide the following functions:

The monitoring center can set up intercom channels to switching station, and therefore

can communicate with distribution rooms.

Switching stations can also call the monitoring center and set up intercom channels.

After intercom channels are set up, bidirectional voice communication is available between the switching stations and the monitoring center.

IP voice intercom reuses existing LAN resources, and achieves bidirectional communication

by only allocating fixed IP addresses and causing no extra time consumption and external

restrictions.

Interface Protocols

The DA environment monitoring system integrates water, temperature/humidity, smoke

sensor status monitoring functions based on Huawei eIVS video surveillance solution, and

therefore achieves video surveillance linkage. Video signal control is based on the SIP

protocol, media stream transmission is based on the RTP protocol, and current/voltage pulse

signals are transmitted between sensors and the DVR/NVR.

Real-time Monitoring and Browsing Real-time monitoring

The system allows users to check real-time pictures of multiple monitoring points on

clients, and allows pictures to be displayed in several panes on a screen. The number of

monitoring panes can be 1, 4, 6, 8, 9, 10, 12, and 16, depending on the number of monitoring points whose real-time pictures need to be simultaneously checked.

During real-time monitoring, users can moves lens upwards, downwards, leftwards, and

rightwards through the lens control panel and can adjust the focus and iris of the lens.

In addition, users can check the real-time videos at different monitoring points in turn.

No manual intervention is required, and videos of the monitoring points can be automatically played at their preset time period in turn.

Video playing on the video wall

The video wall is the common monitoring device in the monitoring center. It consists of

several large-screen HD TVs and can amplify monitoring pictures, making them easier to

be viewed by monitoring personnel.

The system allows monitoring pictures and videos to be played on the video wall. Each

TV can serve a monitoring point, and videos of a maximum of 36 monitoring points can be played. In addition, multiple video wall layouts are supported.

For DA environment monitoring, the major video wall requirements are as follows:

− Specify the videos to monitor by selecting the region > monitoring area > camera

(one or more; if more than one, one main and the others secondary). Users can

monitor video information of all power distribution rooms and switching stations

managed by the monitoring center, monitor multiple channels (1, 4, 9, and 16) of

real-time videos of a same switching station or power distribution room on the same

screen, monitor single-channel real-time videos of several power distribution rooms

and switching stations (1, 4, and 9), and monitor electric device videos recorded from multiple angles.

− Different DA monitoring center can only monitor power distribution rooms and

switching stations within its own control area.

− Related videos can be viewed based on the alarm status information displayed on the power distribution room/switching station layout diagram.

− Multiple monitoring workstations and web users can simultaneously view videos of a power distribution room/switching station.

− Automatic video reset must be supported, allowing cameras at power distribution

rooms and switching stations to be set to default monitoring positions (in normal state,

cameras retain their default positions) and to automatically recover their default monitoring positions within a scheduled time period after the control is complete.

− Manual recording for all videos, and capturing and storing of any one-frame real-time video in JPEG, JPG, or BMP format.

Video Recording Service Manual video recording on the platform

the scheduled recording time expires, the video recording stops. Users can specify the video pre-recording time length before an event occurs.

Upon reception of an event, the platform check for corresponding alarm-triggered video

recording policies. If a policy exists and takes effect, the platform triggers the cameras

specified in the policy to start video recording and storing. The cameras specified in the

policy may be the alarming camera or other cameras. Generally, events such as picture blocking and video loss will not trigger the local camera to start video recording.

Scheduled video recording on the platform

The system allows users to specify the scheduled video recording plan. After the

scheduled recording time expires, the platform automatically generates the video

recording task and start video recording to the platform and stop video recording after

the task is completed. Users can set multiple scheduled video recording plans. The video

recording plans can have overlapping time, and only a video is generated over the

overlapping time.

Advanced ATCA Platform

ATCA is a hardware standard. It is the name of the architecture standard for the hardware

platform rather than the name of a specific product.

The eCNS600 uses the Open Standards Telecom Architecture (OSTA 2.0) platform of

Huawei, which is a server system featuring high density and high performance. The eCNS600

can provide reliable data processing services for carrier-grade telecommunications

applications.

The OSTA 2.0 hardware platform stipulates a series of specifications related to boards,

backplanes, and software for the next generation telecom devices. Based on the ATCA

standard architecture and conforming to the network equipment building system (NEBS) and

European telecommunications standards institute (ETSI) standards, the platform has the

following features:

High rate

The high-speed serial data link and switched structure are used. Therefore, the data exchange bandwidth intra-subrack can reach 2.5 Tbit/s.

High reliability

All boards and subboards are hot swappable. In addition, redundancy is implemented on

all key components, such as power supply, fan, management module, and board of each type. Therefore, the reliability of the system reaches 99.999%.

High scalability

The eCNS600 supports the addition of the interfaces on the ATCA board and cascading between subracks through the interface board within a subrack.

Easy to upgrade

Backplane forwarding bandwidth can be smoothly upgraded to 10 GE. The performance of interface boards is easy to upgrade.

Efficient management

The standard management bus is used, which can manage any part in the system.

The eCNS600 uses the embedded software platform, namely, carrier grade platform

(CGP), which is universally used by the core network products of Huawei. The CGP has the

features such as cross-hardware platform, cross-operating system, and easy maintenance.

Cross-hardware platform

A uniform interface of the hardware platform is provided, which implements the

operation of upper-layer applications on different hardware platforms. Therefore, the

hardware management is independent of the hardware platform.

Cross-operating system

Different interfaces of the operating system at the lower layer are shielded. Instead, a

uniform virtual operating system application programming interface (VOS API) is provided for upper-layer applications.

Easy maintenance

The implementation mechanisms of the functions such as operation and maintenance,

alarm management, performance measurement, call and signaling tracing, data backup, board switchover, and online loading are provided for upper-layer applications.

Backup of important data

The eCNS600 automatically backs up important data, such as the configuration data, performance data, and operation logs.

Operation security management

Different management privileges are assigned to different users. During the user login,

the eCNS600 checks the user identity. After the user login, the eCNS600 maintains the

complete operation to ensure system security.

Hardware redundancy design

All critical boards are configured in the 1+1 backup to ensure the high reliability of the

system.

Fault prevention

The eCNS600 provides protection mechanisms to avoid the following system faults:

− System power off

− Misoperation on the system power switch

− Lightning surge on the system power

− High voltage and low voltage

− Short circuit of power supply

− Current surge and high voltage on the power supply and interfaces

System overload control

In the case of center processing unit (CPU) overload or resource congestion, the eCNS600 adjusts the traffic smoothly to avoid system down.

Board lock and unlock, process lock and unlock

The board and process lock function stops access to new services as required and

gradually removes the existing services within a certain period. The board and process unlock function, however, provides access to new services.

7.2.2 eWBB2.2 DBS3900

With a focus on customer-oriented innovation, Huawei launches a series of products in its

SingleRAN product portfolio, including the distributed E-UTRAN NodeB

(eNodeB) DBS3900 LTE time division duplex (TDD). E-UTRAN is short for evolved

universal terrestrial radio access network. The DBS3900 LTE TDD (referred to as DBS3900

in this document) fully utilizes Huawei platform resources and a variety of technologies to

meet the challenges of mobile network development.

The eNodeB is used for radio access in the LTE system. The eNodeB mainly performs radio

resource management (RRM) functions such as air interface management, access control,

mobility control, and user equipment (UE) resource allocation.

The DBS3900 has two types of basic modules: baseband unit (BBU3900) and remote radio unit (RRU). Featuring a small size and low weight, a basic module can be flexibly and fast

installed to accommodate varied site environment. It also supports flexible software

configuration to meet different capacity requirements. Table 7-2 shows a usage scenario of

the DBS3900.

Table 7-2 DBS3900

Featuring a modular design, the DBS3900 consists of the baseband unit and the remote radio

unit, which are connected using optical fibers through common public radio interface (CPRI)

ports to transmit CPRI signals.

Baseband Unit

The baseband unit, BBU3900, performs the following functions:

Provides ports for establishing an S1 interface between the eNodeB and the mobility

management entity (MME)/S-GW and establishing an X2 interface with another eNodeB.

Provides CPRI ports for communication with RRUs and processes uplink and downlink

baseband signals.

Manages the base station by means of operation and maintenance (OM) and signaling message processing.

Provides an OM channel to the local maintenance terminal (LMT) or iManager M2000 (M2000). The M2000 is an integrated OM system designed by Huawei.

RRU

An RRU is a remote radio unit. One or more RRUs constitute the radio frequency (RF) part of

a distributed eNodeB. RRUs can be installed on a pole, wall, or stand. They also can be

installed close to antennas to shorten the feeder length, reduce feeder loss, and improve the

base station coverage. The RRUs modulate and demodulate baseband and RF signals, process

data, amplify power, and detect standing waves. Table 7-4 shows the exteriors of two RRUs.

Table 7-4 RRUs

Product Features

Various RRU Types

The DBS3900 supports main LTE TDD frequency bands. RRUs configured in the eNodeB are

characterized by their support for various bandwidths, high transmit (TX) power, and high

power amplification efficiency. To meet network deployment requirements of different

operators, two types of RRUs are available:

RRU with four TX channels and four RX channels (4T4R)

RRU with two TX channels and two RX channels (2T2R)

RX is short for receive.

You can configure the software of a 4T4R RRU (that is, RRU3232, RRU3252, or RRU3256)

to divide the channels into two groups. In this way, the RRU can function as two 2T2R RRUs.

63

Energy Saving and Environment Friendly

Due to their small size and modular design, power amplifiers (PAs) do not take up much

space in the equipment room, and resources are saved with the new energy-saving technique.

The following measures also help save energy:

Radio frequency (RF) channels are blocked and power amplifier (PA) voltage is adjusted

if the downlink load reaches a preset threshold.

The power supply unit (PSU) shuts down if the DBS3900 is provided with sufficient

power. The temperature control function controls board temperature. Outdoor

cabinets work in direct ventilation mode, and RRUs work in natural heat dissipation mode.

Flexible Installation

Flexible installation of the DBS3900 simplifies site acquisition and achieves fast network

deployment with a low total cost of ownership (TCO). To reduce the installation investment,

the BBU3900 can be installed on an indoor wall or in a standard cabinet. The RRU can be

mounted on a pole, tower, or concrete wall, or close to the antenna system to reduce the cost

of feeders and power consumption.

High Transmission Reliability and Board Performance

The following features are introduced to ensure high transmission reliability and high board

performance:

Support for the Huawei SingleRAN platform

Support for co-radio resource management (Co-RRM), co-transmission resource

management (Co-TRM), co-operation and management (Co-OAM), and co-radio network plan&radio network optimization (Co-RNP&RNO)Support for route backup

ensuring non-stop transmission of services. SEP features simplicity, high reliability, fast

switchover, easy maintenance, and flexible topology, facilitating network planning and

management.

The S5700-EI supports Ethernet Ring Protection Switching (ERPS), also referred to as

G.8032. As the latest ring network protocol, ERPS was developed based on traditional

Ethernet MAC and bridging functions and uses mature Ethernet OAM function and a ring

automatic protection switching (R-APS) mechanism to implement millisecond-level

PDA Solution




72

protection switching. ERPS supports various services and allows flexible networking, helping

customers build a network with lower OPEX and CAPEX.

The S5700-EI supports redundant power supplies, and can use an AC power supply and a DC

power simultaneously. Users can choose a single power supply or use two power supplies to

ensure device reliability.

The S5700-EI supports VRRP, and can set up VRRP groups with other Layer 3 switches.

VRRP provides redundant routes to ensure stable and reliable communication. Multiple

equal-cost routes to an uplink device can be configured on the S5700-EI to provide route

redundancy. When an active route is unreachable, traffic is switched to a backup route.

The S5700-EI supports Bidirectional Fast Detection (BFD) and provides millisecond-level

detection for protocols such as OSPF, IS-IS, VRRP, and PIM to improve network reliability.

The S5700-EI complies with IEEE 802.3ah and 802.1ag. IEEE 802.3ah defines the

mechanism for detecting faults on direct links over the Ethernet in the first mile, and 802.1ag

defines the mechanism for end-to-end service fault detection. The S5700-EI supports Y.1731.

Besides fast end-to-end service fault detection, the S5700-EI can use the performance

measurement tools defined in Y.1731 to monitor network performance, providing accurate

data about network quality.

Well-designed QoS policies and security mechanisms

The S5700-EI implements complex traffic classification based on packet information such as

the 5-tuple, IP preference, ToS, DSCP, IP protocol type, ICMP type, TCP source port, VLAN

ID, Ethernet protocol type, and CoS. ACLs can be applied to inbound or outbound direction

on an interface. The S5700-EI supports a flow-based two-rate three-color CAR. Each port

supports eight priority queues and multiple queue scheduling algorithms such as WRR, DRR,

PQ, WRR+PQ, and DRR+PQ. All of these ensure the quality of voice, video, and data

services.

The S5700-EI provides multiple security measures to defend against Denial of Service (DoS)

attacks, and attacks against networks or users. DoS attack types include SYN Flood attacks,

Land attacks, Smurf attacks, and ICMP Flood attacks. Attacks to networks refer to STP

BPDU/root attacks. Attacks to users include bogus DHCP server attacks, man-in-the-middle

attacks, IP/MAC spoofing attacks, DHCP request flood attacks. DoS attacks that change the

CHADDR field in DHCP packets are also attacks against users.

The S5700-EI supports DHCP snooping, which discards invalid packets that do not match any

binding entries, such as ARP spoofing packets and IP spoofing packets. This prevents

man-in-the-middle attacks to campus networks that hackers initiate by using ARP packets.

The interface connected to a DHCP server can be configured as a trusted interface to protect

the system against bogus DHCP server attacks.

The S5700-EI supports strict ARP learning, which prevents ARP spoofing attacks that will

exhaust ARP entries. It also provides IP source check to prevent DoS attacks caused by MAC

address spoofing, IP address spoofing, and MAC/IP spoofing.

The S5700-EI supports centralized MAC address authentication, 802.1x authentication, and

NAC. It authenticates users based on statically or dynamically bound user information such as

the user name, IP address, MAC address, VLAN ID, access interface, and flag

indicating whether antivirus software is installed. VLANs, QoS policies, and ACLs can be

applied to users dynamically.

The S5700-EI can limit the number of MAC addresses learned on an interface to prevent

attackers from exhausting MAC address entries by using bogus source MAC addresses. This

function minimizes packet flooding that occurs when MAC addresses of users cannot be found in the MAC address table.

PDA Solution




73

Fine-grained traffic management

The S5710-EI supports NetStream. The NetStream module supports V5, V8, and V9 packet

formats and provides various traffic analysis functions, such as real-time traffic sampling,

dynamic report generation, traffic attribute analysis, and traffic exception report. The

Netstream module enables administrators to monitor network status in real time and provides

applications and analysis functions including potential fault detection, effective fault

rectification, fast problem handling, and security monitoring, to help customers optimize

network structure and adjust resource deployment.

The S5700-EI supports the Sampled Flow (sFlow) function, which uses a sampling

mechanism to obtain statistics about traffic forwarded on a network and sends the statistics to

the Collector in real time. The Collector analyzes traffic statistics to help customers manage

network traffic efficiently. The S5700-EI integrates the sFlow Agent module and uses

hardware for traffic monitoring. Unlike traffic monitoring through port mirroring, sFlow does

not degrade network performance during traffic monitoring.

Easy deployment and maintenance free

The S5700-EI supports automatic configuration, plug-and-play, and batch remote upgrade.

These capabilities simplify device management and maintenance and reduce maintenance

costs. The S5700-EI supports SNMP v1/v2/v3 and provides flexible methods for managing

devices. Users can manage the S5700-EI using the CLI and Web NMS. The NQA function

helps users with network planning and upgrades. In addition, the S5700-EI supports NTP,

SSH v2, HWTACACS+, RMON, log hosts, and port-based traffic statistics.

The S5700-EI supports the GARP VLAN Registration Protocol (GVRP), which dynamically

distributes, registers, and propagates VLAN attributes to reduce manual

configuration workloads of network administrators and to ensure correct VLAN configuration.

In a complex network topology, GVRP simplifies VLAN configuration and reduces network

communication faults caused by incorrect VLAN configuration.

The S5700-EI supports MUX VLAN. MUX VLAN isolates Layer 2 traffic between interfaces

in a VLAN. Interfaces in a subordinate separate VLAN can communicate with ports in the

principal VLAN but cannot communicate with each other. MUX VLAN is usually used on an

enterprise intranet to isolate user interfaces from each other but allow them to

communicate with server interfaces. This function prevents communication between network

devices connected to certain interfaces or interface groups but allows the devices to

communicate with the default gateway.

PoE function

The S5700-EI PWR can use PoE power supplies with different power levels to provide

-48V DC power for powered devices (PDs) such as IP Phones, WLAN APs, and Bluetooth

APs. In its role as power sourcing equipment (PSE), the S5700-EI PWR complies with IEEE

802.3af and 802.3at (PoE+) and can work with PDs that are incompatible with 802.3af or

802.3at. Each port provides a maximum of 30 W power, complying with IEEE 802.3at. The

PoE+ function increases the maximum power of each port and implements intelligent power

management for high-power consumption applications. This facilitates the use of PDs. PoE

ports can work in power-saving mode. The S5700-EI PWR provides improved PoE solutions.

Users can configure whether and when a PoE port supplies power.

High scalability

The S5700-EI supports intelligent stacking (iStack). Multiple S5700-EI switches can be

connected with stack cables to set up a stack, which functions as a virtual switch. A stack

consists of a master switch, a backup switch, and several slave switches. The backup switch takes over services when the master switch fails, reducing service interruption time. Stacks

support intelligent upgrade so that users do not need to change the software version of a

PDA Solution




74

switch when adding it to a stack. The iStack function allows users to connect multiple

switches with stack cables to expand system capacity. These switches can be managed using a

single IP address, which greatly reduces the costs of system expansion, operation, and

maintenance. Compared with traditional networking technologies, iStack has advantages in

scalability, reliability, and system architecture.

Various IPv6 features

The S5700-EI supports IPv4/IPv6 dual stack and can migrate from an IPv4 network to an

IPv6 network. S5700-EI hardware supports IPv4/IPv6 dual stack, IPv6 over IPv4 tunnels

(including manual tunnels, 6to4 tunnels, and ISATAP tunnels), and Layer 3 line-speed

forwarding. The S5700-EI can be deployed on IPv4 networks, IPv6 networks, or networks

that run both IPv4 and IPv6. This makes networking flexible and enables a network to migrate

from IPv4 to IPv6.

synchronizes data from the resource management system (RMS) to ensure the accuracy of

resource data, locates optical route faults quickly and vividly, and provides the GIS mapping

functions.

B/S and C/S Architectures

The U2000 ODN NMS supports browser/server (B/S) and client/server (C/S) architectures.

The B/S architecture supports service features such as iODN device and optical route

management, order management, resource management in the GIS interface, and pipeline resource management.

Fully considering user's operation habits, the U2000 ODN NMS provides friendly and

intuitive GUIs for iODN network management as follows:

Intuitive Device Panel displays patch cord and splicing connections between devices

after configured splicing data is configured or the devices are connected by deploying fiber patch cords and splicing fibers in the GIS map.

Intuitive Device Panel facilitates device status monitoring.

Web clients allow resources locating in the GIS map and accurately display device location to facilitate device information view.

Visualized O&M GUI of the optical cable topology allows users to learn about and monitor the running status of the iODN network.

Efficient iODN Implementation with Order Management

The U2000 ODN NMS uses the order management, the iField, or lighting instructions from

the NMS to visualize iODN order implementation. Electronic implementation ensures

resource accuracy and improves the implementation efficiency.

Order management allows you to perform various order-related operations, such as

creating optical route orders, obtaining orders from the order system, assigning

implementation engineer, and uploading finished orders to the U2000 ODN NMS and

order system.

By default, the U2000 ODN NMS splits a service order into several work orders based

on devices. The U2000 ODN NMS or iField lights the indicators of iODN ports

on which the work orders are to be implemented, automatically verifies implemented

ports, and prompts errors of fiber patch cord deployment. Therefore, engineers can implement the orders efficiently.

The U2000 ODN NMS supports indicator mode switching between All ports mode and Two ports mode to instruct online implementation.

Flexible Configuration and Intuitive View of a Complete Optical Route

The U2000 ODN NMS can schedule optical routes automatically, support flexible optical

route, and intuitively display a complete optical route that meets the filter criteria.

Automatically schedule optical routes.

When a PON physical optical route order, service optical route order, or common optical

route order (in which source and sink devices are main transmission devices) issued by

the order system contains no configured optical route, or when you manually create an

order and select the Auto Schedule Optical Route check box during the creation, the

U2000 ODN NMS automatically schedules the optimal optical route for the optical route

order based on the source and sink port information. If the scheduling succeeds, a PON

physical optical route order, service optical route order, or common optical route order in the To be assigned state is added to the service order list on the U2000 ODN NMS.

Manually configure optical routes.

If the scheduling fails, a PON physical optical route order, service optical route order, or

common optical route order in the configure route state is added to the service order list

on the U2000 ODN NMS. You need to manually configure an optical route following the

instruction of the wizard.

In the Query Optical Route window, the U2000 ODN NMS searches and intuitively displays optical routes based on entered ports, ONUs, optical routes, and user names.

In the FTTx view window, the U2000 ODN NMS quickly displays the logical optical

route from the OLT to the splitter and ONU based on entered port codes (consist of the

device ID and port ID) or optical names, and displays managed devices and their

real time by viewing the topology.

RMS Data Synchronization Ensuring Accurate Resource Data

The iODN brings 3A-level intelligent fiber management, scheduled synchronization of

resource data, and timely and efficient resource data refresh. 3A refers to available, accurate,

and automatic.

Periodically synchronize database resources.

− Data on devices and the resource management system can be synchronized

automatically or manually, which ensures correct port information and avoids wasted implementation to save time and resources for customers.

− Data is automatically updated after finished orders are uploaded, which ensures

correct optical route information and provides powerful support for fault rectification.

Automatically manage fiber information.

The U2000 ODN NMS provides a complete iODN resource management procedure and

refreshes data automatically, which avoids information errors and incompleteness introduced by manual input.

Quick and Intuitive Optical Route Fault Locating After Interconnection with the N2510

OLS

After interconnecting with the N2510 OLS, the U2000 ODN NMS sends pipeline

resource data to the N2510 OLS, which can identify logical fault points.

The N2510 OLS returns the test result to the N2510 OLS for locating faults in the GIS

map. The N2510 OLS sends fault locating information to the N2510 OLS, which will

invoke the GIS interface to display the fault points. Based on the fault locations and

causes, implementation engineers troubleshoot faults onsite in a timely manner to

improve customer satisfaction.

Visualized GIP Map Resources

In the GIS map for resource management, you can input, query, export, locate, and associate

resources. The GIS GUI is user-friendly to facilitate operations.

Interconnection with the MDS6690 to Facilitate Network Resource Plan

After interconnecting with the MDS6690, the U2000 ODN NMS exchanges resource

data with it to manage and utilize resource planning data.

Use the MDS6690 to plan ODN resources and implement the project based on planned

data. After the project implementation is completed and accepted, export data files

in .csv format from the MDS6690 according to uploaded data. Then import the .csv files to the U2000 ODN NMS for resource management.

For ODN network capacity expansion, import resource data in .shp files from the U2000

ODN NMS to the MDS6690. You can utilize existing ODN resource data for network

expansion plan to improve the efficiency.

The scale of a project determines the ICT requirements of a master station of the distribution

automation system, to be specific, the number and performance of servers and switches. The

principles for configuring servers in the power system include redundancy and one server for

each function. Therefore, the more services are required, the more servers and switches need

to be configured, such as SCADA servers, DMS servers, GIS servers, test training servers,

Web servers, and antivirus servers. The more power stations are covered, the higher

performance is required from the servers and switches.

For a master station system that covers 1500 power stations, basic requirements on the ICT

A.3 Appendix 3: Typical Projects

A.3.1 DA Project in Zhoushan City

Background

District P in Zhoushan city, Zhejiang province, China is selected as a sample of state grid

reconstruction in China. The DA reconstruction covers five areas. Real-time monitoring is

required for 10 kV switching stations, power distribution rooms, and ring network cabinets, to

display the real-time status of the entire power distribution network at the dispatch center,

provide technical support for monitoring and dispatching on the power distribution network,

and implement basic SCADA functions (telecommand, telemetry, and telecontrol) and remote

video monitoring (teleview) function on 10 kV electrical devices.

PDA Solution




106

To be specific:

One set of main power distribution system is deployed at the power distribution bureau

of district P, including the SCADA and video monitoring system, to complete the basic

platform construction for the DA.

In three among the five covered areas, 14 switching stations require reconstruction. The

power distribution monitoring terminal (DTU) is installed to collect electrical

measurement statistics and switching status information (telecommand, telemetry, and

alarm information). The telecontrol function is configured. Video monitoring equipment

is installed to monitor the status in video, and to integrate security monitoring measures, including flood alarm, light control, door status switch, and smoke sensing.

An optical communication system is constructed. Optical cables between substations and

switching stations are laid and related communication equipment (Ethernet access boards,

network switching equipment, OLT, ONU, and power modules) is deployed for the

substations and switching stations. New route switching equipment is added at the master station to construct a private power distribution communication network.

Characteristics of Related Communication Technologies

In this solution, the network is divided into three layers, master station control layer (master

station), slave station communication layer (power distribution data network, backbone MSTP

network, and OLT), and access communication layer (ODN and ONU). The communication

devices for DA mainly consist of OLTs at the slave station communication layer and ODN

devices as well as ONUs at the access communication layer. The communication solution is

based on EPONs.

The scheme of cascaded uneven hand-in-hand dual PON interfaces is shown in Figure A-1.

Figure A-1 Solution illustration

The preceding solution is implemented using cascaded uneven optical splitters, to deploy an

ODN with scattered sites.

PDA Solution




107

All ONU products of Huawei support the TYPE D protection with two MAC addresses.

The switching time is less than 50 ms. Inter-board protection on one OLT or across OLTs is supported and the switching time is less than 50 ms.

EPONs support the QoS-based dynamic bandwidth allocation mechanism required by the electricity industry, to ensure that important services are executed first.

Industrial electrical devices can work stably for a long time in harsh environment, such

as dramatic temperature difference, condensation due to high humidity, high voltage fluctuation, and high electromagnetic radiation.

Customer Benefits

Extremely low latency, which satisfies the real-time bidirectional communication requirement

of power distribution data and ensures the real-time performance of power distribution

services (telecommand, telemetry, telecontrol, and teleview), and prevents power distribution

accidents caused by the failure to execute telecontrol commands due to network latency.

99.999% availability of the communication network, which ensures 7x24 hours of

non-interrupt running of power distribution services and ensures the correctness of power

distribution data. Key services, such as telecontrol commands, are executed first to prevent

power distribution accidents.

A.3.2 DA Reconstruction Project in Qingdao City

Qingdao Power Supply Company is directly subordinate to Shandong Electricity Corporation,

and is responsible for the power supply to seven districts and five counties of Qingdao. The

coverage area is 10654 square kilometers with millions of customers.

Background

The first two phases of the DA project cover most of the south and north parts of the city,

involving 104 10 kV lines and 19 substations.

Phase one of the project covers three areas with 15 ring networks. DA reconstruction is

performed on 38 10 kV lines:

− Six cable ring networks for new residential communities in area A, consisting of one switching station and 21 power distribution rooms (controlling 45 switchgears)

− Eight aerial ring networks in area B, controlling 61 pole mounted switches

− One hybrid (aerial and electrical cable) ring network in area C, consisting of four power distribution rooms and eight switchgears

Phase 2 of the project covers most areas in the north and some areas in the south of the

city, with 15 aerial ring networks, 10 electrical cable networks, 15 35 kV substations,

more than 60 10 kV lines, 6 switching stations, and 20 power distribution rooms. In total,

65 pole mounted switches, 7 ring network cabinets, more than 100 FTUs, and more than

50 motors are constructed.

DA reconstruction is performed to 12 10 kV electrical cables to form six electrical cable ring networks for six power distribution rooms.

Till now, the first two phases are complete, using Huawei DA EPON solution. 40 OLTs and

thousands of MA5621 have been deployed. The DA implementation rate of 10 kV lines in

urban areas had reached 50.7%. The DA implementation coverage area in Qingdao is the

largest in China, with the most advanced equipment, technology, and system.

PDA Solution




108


According to the requirements of Qingdao Power Supply Company on high bandwidth, long

distance, and high security performance, Huawei deploys optical cables for the DA

communication. The optical cables are non-metal ADSS optical cables, featuring wide

transmission spectrums, strong anti-electromagnetic interference capability, and strong

anti-lightening strike capability. Optical fiber transceivers with four optical ports are used to

form two-fiber self-healing rings, which improves network reliability. At the same time,

the DA communication system supports network management functions. A network can be

monitored at the central station, which greatly shortens the time of network fault diagnosis

and improves maintenance efficiency. Therefore, the DA communication system of Huawei

features high availability.

According to the structure of the DA communication network of Qingdao, the network has

high availability and high efficiency. The network performance is high and satisfies the

requirements of a DA system on communication.

Figure A-2 xPON network topology of Qingdao DA communication network

Benefits

After reconstruction, devices on 10 kV lines are replaced with more advanced devices, the

power supply radius is smaller, the insulation rate is higher, a fault segment on a 10 kV line

can be automatically isolated in tens of seconds, and the network can be reconstructed. The

quality, availability, and security of power supply are higher, bringing great benefit in all

aspects.

PDA Solution




109

The qualification rate of voltage increases from 99.5% to 99.9%.

Distribution line loss is decreased from 7.5% to 5.3%.

The power availability of 10 kV customers is improved from 99.96% to 99.99%. The

power outage time for each house is reduced by 2.628 hours each year, and power loss is reduced by 3341 KWH each year on average.

The workload for checking lines is greatly reduced and fewer workers are hired.

Because the fault rate is lower and the range of power outage caused by accidents is

smaller, the power supply promises made to the society are better kept. Customers'

attitude of the power supply company is greatly improved, making it possible for the company to become a first-class power supply company in the world.

A.3.3 DA Reconstruction Project in Zhuhai City

This project is a pilot project on electric private broadband wireless networks (PBWA) of the

Comprehensive Communication Solution Research Project of China South Power Grid,

implemented by Guangdong Electric Power Design Institute.

Background

The general target of this project is to build a wireless broadband access system covering 10

110 kV/220 kV substations in Zhuhai city step by step, in order to implement the DA

construction, emergency communication, real-time monitoring, and real-time metering

collection of the power distribution network.

In this phase, one set of TD-LTE core network devices (NAU, USN9810, and UGW9811) is added in the central equipment room of the power supply bureau of Zhuhai.

In the training building of the power supply bureau, power supply development building,

power supply bureau, six substations, and a business hall, one 1.8G TD-LTE DBS3900 device is added for each.

In the coverage range of the preceding 10 sites, 60 TD-LTE access terminals are built to

implement the bidirectional communication between DA points and measurement

automation points.


The TD-LTE base stations deployed for the 10 substations cover the entire Zhuhai, with three

target areas: dense urban areas (requiring frequent switching), spacious sub-urban areas, and

emergency exercise areas. The three types of areas cover the most typical scenarios in the

power industry. Therefore, this project can show the coverage and capacity of a wireless

broadband network in the power industry. The 10 TD-LTE base stations use the

networking with 1.8 GHz and 5M intra-frequency. The base stations are connected to the

power transmission network and the TD-LTE core network equipment in the central

equipment room in the uplink direction. The general architecture of the wireless broadband

private network is shown in Figure A-3.

Figure A-3 Network topology for the PDA LTE network in Zhuhai

In old urban areas of Zhuhai, wired access is difficult to deploy for the DA communication

network. The deployment cost is high, the automation degree of existing components is low,

and remote control is impossible. In Huawei's LTE wireless access solution, base stations are

deployed at substations, to build a wireless broadband access system that covers the 10 110

kV/220 kV substations in Zhuhai. This solution helps achieving the goal of implementing

the DA, emergency communication, real-time monitoring, and real-time electricity amount

collection of the power distribution network of Zhuhai.
