About this guide

The purpose of this application guide is to

help the reader configure a Smart-Gear

PDS switchgear lineup. Each section

contains information important inselecting equipment to meet requirements

for todays modern medium-voltage

switchgear.

To make it easy to configure a Smart-Gear

PDS switchgear lineup, the various

selections in this application guide are

presented as building blocks, called

application modules. These application

modules are described in detail using

tables and one-line diagrams.

Each section contains information to help

the reader determine the powerdistribution system configuration that best

meets their application, protection,

operation and overall functionality needs.

Please note the information contained in

this application guide is a general

description of the technical options

available for Smart-Gear PDS. Certain

features or configurations may not be

applicable or appropriate for your specific

needs.

Smart-GearTM power distribution solution (PDS)

Siemens Energy, Inc., a world leader in

innovative technologies, has taken another

step forward by creating the total solution

in medium-voltage, metal-clad switchgear.

In response to our customers' need forstandard switchgear that is programmable

and self-monitoring, Siemens has

combined its advanced switchgear,

protective relay products and its

engineering experience to deliver a total

package to customers: Smart-GearTM power

distribution solution (PDS).

With Smart-Gear PDS, users are provided

the following features and benefits:

Reduced control wiring for increased

reliability digital and fiber-optic

circuits instead of hard-wired circuits

Self-monitoring feature-rich increased

operational reliability

Programmable easy to implement

complex schemes with flexibility for

future changes

IEC 61850 communication protocol

providing integrated control,

monitoring and protection

Usage-based preventive maintenance

notification

Faster commissioning and start up.

Smart-Gear PDS is equipped with standard

self-monitoring features, designed

specifically to enhance the performance

and reliability of the switchgear. With

Smart-Gear PDS, the user is notified in

advance of potential problems such as

those in trip circuit and space heater

circuits. Also, based on the usage of the

equipment, the user will be notified when

periodic recommended preventive

maintenance is needed.

Using IEC 61850 communication protocol,all control, monitoring and protection

functions are accomplished through a

redundant fiber-optic connection between

protective relays and bay controllers. This

communications capability reduces the

need for much of the control wiring

necessary to implement and change

complex schemes, resulting in reduced

field testing and commissioning time.

Nothing contained in this application

guide will constitute a warranty or

guarantee by Siemens that the Smart-Gear

PDS or the configurations described in this

guide are fit for your intended purposes.Your local Siemens representative will be

happy to assist you with configuring a

solution to meet your specific needs.

Application-based approach:

A new way of specifying switchgear

An application-based approach to

configuring switchgear offers a new way

of thinking. For example, with an

application-based approach, all switchgear

functions including automatic transfer

schemes, circuit breaker types, protection

schemes and other special switchgear

functions are described in terms of

application modules. When combined,

these application modules define the

operation and configuration of a Smart-

Gear PDS solution.

All software programs and digital and

hard-wired circuits used to perform specific

operations or protective functions are

referred to as apps, which are protective

relay hardware and software programming

(continuous function chart (CFC)

programming) designed specifically for

application modules.

OverviewSmart-GearTM PDS is a programmable and

self-monitoring power distribution solution

that combines Siemens type GM-SG non-

arc-resistant or type GM-SG-AR arc-

resistant, medium-voltage switchgear and

Siemens SIPROTEC protective relay

technology to offer one of the most

advanced standardized switchgear

solutions in the industry. With its standard

self-monitoring features and

programmable capabilities, Smart-Gear

PDS redefines how switchgear is specified,

engineered, operated, installed and

maintained.

Feature rich

Smart-Gear PDS is rich in standard

features, specifically designed to monitor

critical functions such as trip circuit

integrity, space heater operation, vacuum

interrupter wear, circuit breaker status,

operations and more.

In traditional switchgear, many of thesefunctions and features have to be specified

and engineered specifically to the order,

but with Smart-Gear PDS these self-

monitoring features are standard. For a list

and description of these features and

more, refer to the smart features section

beginning on page 6.

Switchgear

Smart-Gear PDS is available across the

entire GM-SG product family with Siemens

type GM-SG or type GM-SG-AR metal-clad

switchgear through 15 kV.

For more detailed information on Siemens

type GM-SG metal-clad switchgear, refer to

Siemens type GM-SG selection and

application guide E50001-A122-X-4A00,

Web site at www.usa.siemens.com/energy

or contact your local Siemens

representative.

Since a Smart-Gear PDS switchgear lineup

has fewer control devices, it provides

increased functionality and reliability. This

also means fewer control wires with

greater flexibility for modifications and

future changes or expansion with digital

circuitry.

Smart-Gear PDS is one of the most

advanced standardized medium-voltage

switchgear solutions in the industry.

OverviewProtective relays and metering

Smart-GearTM PDS is supplied with the most

advanced protective relays in the industry,

Siemens SIPROTEC protective relays. These

protective relays are fully equipped with

the advanced protection functions and

Ethernet-based IEC 61850 communications

protocol over a redundant fiber-optic cable

for high-speed data transmission. Refer to

protection functions and metering sectionbeginning on page 24 for a detailed

description of the protective relay

functions provided with Smart-Gear PDS.

For additional details on Siemens SIPROTEC

relays, refer to SIPROTEC Numerical

Protective Relays Catalog SIP 2008 E50001

K4400-A101-A5-7600, Web site at www.

usa.siemens.com/energy or contact your

local Siemens representative.

The difference

Smart-Gear PDS is equipped with more

features and benefits than traditional

switchgear. All applicable self-monitoring

features, described in the smart features

section beginning on page 6, are provided

with the standard package. These self-

monitoring features enhance the reliable

performance of the equipment. With

Smart-Gear PDS, less control wiring isrequired to implement simple or highly

complex control schemes. Communication

capability enables interface between

protective relays for each circuit breaker,

interface with other Smart-Gear PDS

switchgear lineups, remote control

capability and interface with many SCADA

systems deployed with current

communication protocols.

Simplification from design and

specification, to commissioning and

operation, is at the heart of Smart-Gear

PDS, the intelligent choice in yourselection of medium-voltage switchgear.

Smart features

Standard features

Circuit breaker operating cycles

monitoring

This smart feature alerts the user when the

drawout circuit breaker is approaching its

pre-set threshold of operating cycles for

scheduled maintenance. The threshold is

pre-set at the factory to provide advance

notification at 80 percent usage (20

percent of the remaining operations) of

the recommended operations cycle.

Trip-circuit monitoring

In the event of a fault, the user needs

confidence that the circuit breaker trip

circuit will open the circuit breaker. This

feature monitors the integrity of the trip

circuit and provides the user notification of

non-functionality of the trip circuit

resulting from failed trip coil or blown trip-

circuit fuse.

Close-circuit monitoring

(type SG-64 only)

Monitoring the status of the close circuit is

critical in cases where transferring and

redirecting power is required, such as with

a main-tie-main automatic transfer

scheme. This feature monitors the integrity

of the close circuit and provides the user

notification of non-functionality of the

close circuit resulting from a failed close

coil or blown close-circuit fuse.

Vacuum interrupter wear monitoring

This smart feature monitors the remaining

expected life of the vacuum interrupters by

calculating the accumulated load, no-load

and short-circuit interruption data. Basedon the calculation, the user is given

notification of vacuum interrupter contact

wear. Means for visual verification of the

vacuum interrupter during circuit breaker

inspection is standard.

Circuit breaker racking position

indication (type SG-64 only)

The position status of the circuit breaker is

connected to binary inputs on the

protective relay, and is thus available for

local and remote monitoring and control

logic. The circuit breaker positions include

connected, disconnected and test.

Integrated controls

Two things visibly different about Smart-

GearTM PDS compared to traditional

switchgear are fewer control devices andsignificantly less control wiring. With

Smart-Gear PDS, the circuit breaker control

switch function (CS) and lockout protective

relay function (86) are an integral part of

the protective relay. Having these control

functions in the protective relay enables

the user to change control logic

electronically without having to change

the hard-wired circuitry.

Integrated power monitoring

Main, feeder and tie circuit breakers are

equipped with integrated power metering(one percent accuracy) including current,

voltage and power measurement

functions. Current measurements include

Ia, Ib, Ic, min/max and min/max current

demand. Voltage measurements include

phase voltages and min/max. Power

measurements include peak demand kW,

peak demand kVAr and peak demand kVA,

min/max power factor, min/max frequency,

set-points and pulse counter. Min/max

data also includes date and time.

Programmable circuit breaker

control interlocking

Continuous function chart (CFC)

programming software makes digital

circuit breaker interlocking available for a

Smart-Gear PDS. This technology enables

interlocking of multiple circuit breakers in

the lineup, enabling user modification

without complicated and timely wiring

changes and retesting. All interunit

connectivity between circuit breakers is

through IEC 61850 communication

protocol over redundant fiber-optic

connections.

8/48

Smart features

Voltage transformer monitoring

Three-phase, wye-connected (required)

voltage transformers are monitored for

proper operation including blown fuse and

voltage transformer failure. As with other

event data, this information is retained in

the protective relay ready for local and

remote monitoring.

Current transformer monitoring

Current transformers are monitored for

proper phase and current summation.

Information is retained in the protectiverelay ready for local and remote

monitoring.

Bus protection (device 50B)

Reverse-zone interlocking is used to

distinguish a bus fault from a through-fault

and uses IEC 61850 generic object

oriented substation event (GOOSE)

messaging.

Space heater operation monitoring

Space heater functionality is important for

long-term operation and reliability ofswitchgear, particularly under conditions

of high humidity or in outdoor

applications. Many switchgear failures

result from improper use of space heaters

including instances in which the space

heaters were not energized or were never

wired to the power source. With Smart-

Gear PDS, the operation of the space

heaters is under constant monitoring to

improve the long-term reliability of the

power distribution system.

Large display (type SG-64 only)

A large display is provided with the

Siemens SIPROTEC type 7SJ6415 protective

relay solution and is provided for all main

circuit breakers.

IEC 61850 enabled

Each protective relay is equipped with

IEC 61850 communication protocol. More

information on IEC 61850 is included in

the communications and controls section

beginning on page 27.

Programmable main-tie-main transfer

scheme

CFC programming software makes digital

implementation of automatic transfer

schemes available for Smart-GearTM PDS.

Like the programmable circuit breaker

interlocking feature, this feature enables

the user to modify the scheme without

complicated and timely wiring changes

and retesting. All interunit connectivity

between circuit breakers is with redundantfiber-optic connections.

Fan cooling monitoring for a 4,000 A

circuit breaker(type SG-64 only)

This feature monitors the cooling fan for a

4,000 A circuit breaker. The cooling fan air

flow switch provides the input signal to the

protective relay for local and remote

monitoring.

Arc-flash detection

Arc-sensing protection is available with

Smart-Gear PDS.

Application modules

System application modules

System application modules are used to

define the operation and protection of the

entire switchgear lineup. All automatic

transfer and circuit breaker interlock

application modules are implemented with

CFC programmed protective relays, IEC

61850 communications over fiber-optic

cable. Tables 2, 3 and 4 describe these

system application modules in detail.

Automatic transfer application modules

With Smart-Gear PDS, four types of

automatic transfer application modules are

offered. These digital automatic transfer

schemes are configurable for automatic or

manual restore, open- or closed-transition

and preferred or non-preferred sources.

Refer to the definitions and terminology

section on page 35for detailed

descriptions of these terms. The available

automatic transfer application modules are

described in Table 2 on page 10. All time

delays and timing will be determined atthe engineering stage.

Application modules

This guide uses an application-based

approach described on page 2 to

configuring Smart-GearTM PDS. All

automatic transfer schemes, interlock

schemes, circuit breaker types, protection

schemes, remote control solutions and

interfaces, generator controller and

paralleling solutions, and other special

applications are described in Smart-Gear

PDS as application modules.

Application modules are the building

blocks used for configuring a Smart-Gear

PDS switchgear lineup. These modules are

pre-configured applications designed to

perform specific functions.

Protection functionsand metering

Protection functions and metering

With Smart-Gear PDS, protection and

metering functions are pre-defined based

on the specific application of the circuit

breaker and, because of this, the process

of configuring circuit breakers is easy.

All protective relays used for each circuit

breaker application module are equipped

with the IEC 61850 communication

protocol.

Table 12 describes the protection and

metering functions that are standard or

optional for each circuit breaker

application module.

Communicationsand controls

Because IEC 61850 is the global standard

for substation automation communication

protocol, it is the standard communication

protocol used for Smart-GearTM PDS. IEC

61850 communicates over TCP/IP networks

and/or substation LANs using high-speed

switched Ethernet (baud rate is 100 Mbps).It can be mapped to the most well-

established protocols, including GOOSE or

peer-to-peer messaging and Web services.

Since IEC 61850 is an open protocol that

supports communication for monitoring,

control and protection functions, it offers

significant advantages for interfacing

among circuit breakers within a lineup as

well as other devices throughout the

power distribution system.

All Siemens type SIPROTEC protective

relays used in Smart-Gear PDS are

equipped for IEC 61850 communications.

The automatic transfer and circuit breaker

interlock schemes described in application

modules beginning on page 9 are achieved

through continuous function chart (CFC)programming, and initiated by the

protective relays through IEC 61850

GOOSE messaging communication. This

digital capability significantly reduces the

number of control wires, especially

interunit (wiring between sections) control

wiring.

There are three communication and

control application modules, including

local control, remote-local control and

remote control application. Each control

and monitoring module is a building block

for configuring an advanced

communications network, in which the

local control and monitoring are the

foundation for all other control and

monitoring modules.

27


28/48


Smart-GearTM PDS network:

local control and monitoring

Local control and monitoring is

accomplished among the Siemens type

SIPROTEC protective relays within the

Smart-Gear PDS switchgear lineup. The

protective relays are pre-programmed

using Siemens DIGSI 4 software to meet

the specific application requirements,

including automatic transfer schemes and

circuit breaker interlock schemes as

described in application modules on page

9. For Smart-Gear PDS, local operation andcontrol (closing and opening) of the circuit

breakers are accomplished through the

protective relay circuit. All automatic

transfer, circuit breaker interlocking and

lockout functions are accomplished

through protective relays within the local

digital network.

The interface among circuit breakers is

accomplished with CFC programming, IEC

61850, peer-to-peer/GOOSE messaging

and fiber-optic connections. The input/

output between a protective relay and a

circuit breakers is hard-wired.

Main-tie-main automatic transfer schemes

are accomplished with GOOSE messaging

and CFC programming, which is a more

reliable and flexible approach to system

automation.

Definitions andterminology

Apps are software programs designed to

be uploaded to the Smart-Gear PDS

switchgear lineup network.

Automatic transfer scheme is the system

that enables automatic transfer of

electrical power between one circuit

breaker to another circuit breaker.

Application modules are the building

blocks for configuring a lineup of

switchgear.

Continuous function chart (CFC)

programming is the diagrammaticlanguage for the specification of mixed

protective relays and other discrete

continuous embedded systems. CFC

permits the conversion of technological

specifications into executable automation

programs.

Control wiring is the copper wiring

between secondary control devices.

DIGSI 4 is a Siemens tool for setting

protective relays using MS Windows.

DIGSI 4 is the logical innovation for easy-

to-use and user-friendly setting,commissioning and operating of all

SIPROTEC protective relays, regardless of

version.

Digital circuitry is the communication

interface between intelligent electronic

devices (IEDs).

Fiber-optic cable is flexible glass material

used to transmit data.

GOOSE is the abbreviation for generic

object-oriented substation events and is

the high-speed data transmission that

bypasses normal communication.

Hard-wired circuits are the copper wire

interfaces among secondary devices.

IEC 61850 is a global standard for

substation automation communication

protocol and is open Ethernet-based.

Integrated controls is the combination of

multiple functions into fewer devices.

Interlocking, circuit breaker

interconnects two or more circuit breakers

with control circuits to open or close (or to

prevent closing) depending on the

application requirements.

Interlocked, digital connects two or more

circuit breakers via IEDs to open or close

(or to prevent closing) depending on the

application requirements.

Interoperability is the ability of

equipment to easily interface with other

equipment supplied by different

manufacturers.

Programmable means equipment can be

programmed to function.

Restore, automatic is the automatic

return to the preferred power source from

the non-preferred source.

Restore, manual is the manual return to

the preferred power source from the non-

preferred source.

Scalability is the ability of a system to

handle additional hardware and functions

with little impact on performance.

Self-monitoring is the capability of the

equipment to monitor its own functionality

and advise (alert) the operator.

Source, non-preferred is secondary or an

alternate power source.

Source, preferred is the primary or

normal power source.

Transition, closed is the closing of a

circuit breaker prior to transferring of

power, typically the tie circuit breaker in a

main-tie-main breaker configuration.

Transition, open is the opening of a circuit

breaker prior to transferring of power,

typically the tie circuit breaker in a main-

tie-main circuit breaker configuration.

Usage-based maintenance is the

advanced notification the equipment

provides to the user of recommended

maintenance based on time and/or

operations.
