At the begining…a challenge…
the digital substations 80’s: several countries carried out experiments for EHV digital substations (USA,
Canada, Japan, France, Spain…) => many challenges were to be tackled:
Performances,
interfaces
Data representation & interoperability
Variousness…
Early 90’s: first attempts for a standardization at CIGRE, EPRI/IEEE…
CIGRE 35 => PiComs
AHG in TC57 on substation architecture, decision in 1995 to launch 3 WGs :
WG10: archirecture, WG11: control level, WG12: interfaces with process
End of 90’s: agreement between IEC & IEEE => stds will be developedin one place
.

TC57 : Power system information management &
associated information exchange
To prepare international standards for power systems control
equipment and systems including EMS, SCADA, DA, teleprotection,
and associated information exchange for real-time and non-real-time
information, used in the planning, operation and maintenance of
power systems.
Power systems management comprises control within control centres,
substations and individual pieces of primary equipment including
telecontrol and interfaces to equipment, systems and databases, which
may be outside the scope of TC 57.

Interfaces
IF1: protection-data exchange between bay and station level
IF2: protection-data exchange between substations. This interface refers both to analog data e.g. for line differential protection and binary data e.g. for line distance protection
IF3: data exchange within bay level
IF4: Current transformer (CT) and Voltage Transformer (VT) instantaneous data transport (especially samples) from the process to the bay level. This comprises in the reverse direction also the protection trip
IF5: control-data exchange between process and bay level
IF6: control-data exchange between bay and station level
IF7: data exchange between substation (level) and a remote engineer’s workplace
IF8: direct data exchange between the bays especially for fast functions like interlocking
IF9: data exchange within station level
IF10: control-data exchange between the substation and remote control centre(s)
IF11: control-data exchange between substations. This interfaces refers to binary data e.g. for interlocking functions or inter-substation automatics

The Bus Topology
Four main possibilities:
Single and double star• Only 1 or 2 Main Switches
• High Number of ports per switch
• High performance Switch necessary
Single and double three• IEDs are chained towards the Bay Level
• Latency in transversal Communications
• Improved resiliency compared with star
Mesh

The Ring Topology
Standard de facto in Industrial
Ethernet Networks
Single element failure protected
Multiple variants• Single ring
• Multiple rings chained
• Ring of the rings
Interconnecting points does not
increases significantly the risk
Deterministic topology
Balanced trade off between
efficiency and cost

Piece of Information for COMmunication (PICOM)
Interchange of information between two logical nodes
Defined in the specification phase by the user
Part 5 defines several performance classes based on types
Type 1: Fast messages (“Protection”)
Type 2: Medium speed messages (“Automatics”)
Type 3: Low speed messages (“Operator”)
Type 4: Raw messages (“Samples”)
Type 5: File transfer functions
Type 6: Command messages and file transfer with access control

Publish – Subscription mechanism over Ethernet frames
Event-driven mechanism
Used for fast transmission of information (trips, blockings, …)
A dataset and a GOOSE Control Block is used
Published in a multicast address over a VLAN
Each message has three protocol control values
State change number: Increase by one when a new event is generated
Sequence number: Increase by one each time a Goose message is repeated. Reset to 0 when a new event is generated
Time Allowed To Live: Time for the subscriber to wait for the next repetition of the Goose message

Client-Server mechanism over MMS association and TCP
connection
Interested in status, quality and time tag information
Time constraint is around 200-500 ms
A dataset and a Control Block is used
Two types of service: Buffered and Unbuffered reports
Buffered report store reports when there is no connection with
the client to send them after reconnection

61850-9-2: Sampled values
Sampled values are mapped over Ethernet
Can be unicast or multicast
Needs PPS signal
The number of samples per period is configured
Samples are numbered sequentially and reset each second
Multiple samples can be sent in the same ASDU
Control Blocks are handled using MMS (client-server services)
Typical rates: 80 samples/cycle (2 Mbps), 256 s/c (16 Mbps)
IEC 61850-9-2 LE is a specific profile widely used today

Tools for exploring IEDs
IEC 61850 provides semantic interoperability
Independent third party tools can connect to any IED
To connect to the IED
To subscribe to IED Goose messages
To recover the IED data model
To acquire real time information from the IED
To enable reports available in the IED
There are a lot of different tools in the market for this purpose
There are also tools for simulating IEDs
14/10/2015
75
Tools for maintenance and diagnosis
Tools for maintenance and diagnosis are out of the scope of
the standard
Utilities to specify what they need for maintenance
Specific tools should be developed for utilities
A engineering mapping information is usually needed for
maintenance
Maintain the well-known semantic of information
A mapping between IEC 61850 data model and engineering semantic
A troubleshooting guide related to communication and lose of service is
needed, as maintenance people have to know the implications
14/10/2015
76
Tools for testing
IEC 61850 edition 2 has improved testing functionalities
In a digital world, isolating IEDs implies isolating messages in
the network
Testing tools are needed and must cover edition 2
functionalities
Clear procedures must be defined for testing
Tools to implement the procedures in order to automatize the
process
Keep in mind that factory, commissioning and maintenance
tests are similar, but they are not the same

Roles in IEC 61850: Who is who?
Roles
End user: the ultimate owner, operator
Integrator: in charge of the detailed design
Constructor: group that does the physical build
Vendor: supply products
The same company or group can have different roles
The utility can be end user and also integrator
A company can be integrator, constructor and vendor
Roles – Companies relation depends on the project type
(turnkey project, internal project, outsourcing, …)

Guideline for Technical Committees
and Working Groups on Using IEC
618501) Scope
The guide is for working groups (in / out side TC57) that intend to use IEC 61850 as a base standard within the scope of their work. The document shall help to identify the required steps in applying IEC 61850 for standardization work and shall provide guidelines for the individual steps.
Within that scope, the document addresses the following topics.
For the usage of IEC 61850 for new domains, the initial analysis how IEC 61850 can be used and what extensions may be required. The results of that step may be documented in a technical report.
The extension of the IEC 61850 object models for new domains. The typical work associated with that is, to identify existing logical nodes that can be reused with or without extensions and to define new logical nodes.
Product standards for products that have an interface based on IEC 61850.
IEC 61850 profiles for domains.
