IEC TC 57 Standards



The Goal: Interoperability and IntegrationThe ability of a system to exchange information with other systems and interact with each other in order to perform a useful function for the user.

5

IEC 61850 Tutorial



Interoperability and Integration

Easy to Achieve:

Nearly anything is possible with enough money and development effort

6

IEC 61850 Tutorial



A Better WayInteroperability and Integration without having to create, support, maintain, improve, and fix it all yourself:Where applications and devices are inherently capable of interoperating with other systems and performing integrated application functions in a cooperative and distributed manner.

This is only possible with Standards

This is the goal of the IEC TC57 standards

Traditional Protocol StandardsSpecified how you arrange bytes on the wire in order to transfer bytes of data between a device and an application

Good News: It worked! Device communications costs were lowered.

Bad News: No standard for data representation or how devices should look and behave to network applications. Some Interoperability but not Integration

CIM and IEC 61850 Difference in Topology

Are these the same objects?

IEC 61970-301 EMS Diagram IEC 61850-6-1 SCL Diagram38

IEC 61850 Tutorial



Why the need for persistent IDsIEC 61850-6-1 Substation Configuration Language (SCL) files are used to define substation power system toplogy and IED functions and configuration. SCL files have internal referential integrity through the use of names. When merged/imported into a unified model, names can be duplicated. It is difficult to pick up changes if the name changes. CIM uses GUIDs GUIDs are the better solution Common usage Not ambiguous Isolates identification of objects from names39

IEC 61850 Tutorial



Other Harmonization IssuesIEC 61850 use of SI Units to be brought into CIM Adding topological elements to IEC 61850 and CIM to enable easier path back and forthAll IEC 61850 topology is within a substation

IEC 61850 Tutorial



Moving Design to OperationsSince the advent of the CIM the ability to move models from planning to operations (and vice-a-versa) in a multi-vendor environment has improved.To be expected through use of standards. Eventually enable wide exchange of planning models like ENTSO-E and WECC.

EMS and planning use a set of tools that have been harmonized to enable the flow of information between them.

43

IEC 61850 Tutorial



Moving the Design to Substations

Power system engineers use a completely different set of tools supporting a completely different set of standards to define the substation automation and protection systems.IEC 61850 Tutorial

44



Its About ProductivityThe effort and knowledge put into the planning and operations models that isnt embodied in the one-line diagrams is lost and has to be transferred manually into the substation design through the engineering process duplicating previous effort.

If the tools used a common set of standards the flow of information can be automated enabling topology, SCADA, protection, communications, settings, etc. to be preserved and leveraged through the engineering process.

IEC61850 View of DevicesOnly network addressing requires configuration in the remote client. Point names portray the meaning and hierarchy of the data with no mapping to I/O required. Point names can be retrieved from the device automatically without manual intervention. All devices share a common naming convention. Device configurations can be exchanged using IEC61850-6-1 (SCL) files

59

IEC 61850 Tutorial



More on SCL (IEC61850-6)SCL Substation Configuration Language a standardized method of describingSubstation power systems Device configuration

SCL can be used to unambiguously describe user requirements for systems and devices. SCL can be used to configure applications without connecting to devices. SCL enables third party tools for configuration promoting choice and flexibility. Enables a model-driven approach to power system engineering that preserves system knowledge and applies it to reducing configuration and commissioning costs.60

IEC 61850 Tutorial



BenefitsReduced configuration costs:Eliminates most manual configuration via automatic point name retrieval from devices Common naming and object models eliminates ambiguity and manual mapping of data points.

Equipment migrations occur with minimal impact on applications. Application changes have minimal effect on devices, network or other applications. Users can specify equipment more precisely eliminating delays and costly rework. Adapting SCL into the engineering process enables more effective design and commissioning resulting in higher productivity and higher value to the enterprise.61

IEC 61850 FeaturesClient Server Communications:Clients can retrieve all data object definitions and device behavioral information over the wire with minimal configuration Simple and complex data access using standardized object names using power system context for the majority of substation functions required. Named data sets to collect data elements into groups for reporting. Buffered and Unbuffered report by exception of Data Sets configurable by clients via named control blocks. Comprehensive control modes including direct and SBO with or without enhanced security. Logs for event data with configurable access by clients via named control blocks. Named control blocks for clients to control multi-cast messaging (GOOSE) Named control blocks for clients to control process bus messaging of sampled values Settings group controls via named control blocks enabling client control of settings. Substitution functions enabling clients to override values for status and measurements.92

IEC 61850 Tutorial



IEC 61850 FeaturesMulti-cast messaging enables devices to broadcast status, control, and I/O information to many devices simultaneously:Generic Substation Status Event (GSSE) supports distribution of 2-bit status information over the station bus. Generic Object Oriented Status Event (GOOSE) supports distribution of a user defined data sets over the station bus. Typically user configurable in the device. Sampled Values (SV) supports distribution of time sampled data such as measurements, status, and other I/O signals over a separate process bus Unicast services for these functions enable verification and discovery of the data contained in the multi-cast messages without requiring client/server communications.

Standardized XML based substation configuration language (SCL) for exchange of power system and device configuration information using a standard format. IEC 61850-6

Some TermsNetwork Access Methods:Master Slave a master controls slave access to the network (e.g. DNP3) Peer-to-peer any entity may send data to any other peer entity on the network without having to coordinate with a master (TCP/IP-Ethernet).

Client-Server defines roles between 2 peers on a network.

Unconfirmed ServiceA Report is when a server sends data without a client request.

In IEC 61850-8-1 reports are mapped to the MMS InformationReport serviceInformationReport is essentially a way to send the data from a Read response without the client having to ask for it

Functional ConstraintsThere are many data attributes in an object like a breaker that have related useControl, configuration, measurement, reporting, etc.

Functional Constraints (FC) is a property of a data attribute that characterizes the specific use of the attribute.

Useful to functionally organize data attributes to provide structure and context.

Service Tracking CDCsUsed in ACSI (IEC 61850-7-2) to provide the means to control and track control blocks and commands.Replaces the object type descriptions of control blocks in Edition 1. Mapping in IEC 61850-8-1 results in substantially similar objects and interactions.

Based on a general Common Service Tracking (CST) CDC
