Recommended Practice for Implementing an IEC 61850-Based Substation Communications, Protection, Monitoring, and Control System

active, Most Current
Organization: IEEE
Publication Date: 18 May 2017
Status: active
Page Count: 67
scope:

This recommended practice outlines the necessary steps and procedures implementers of IEC 61850 in substations should undertake in a multi-vendor equipment environment

It is not the intent of this recommended practice to change the IEC 61850 standard, but treats the standard as providing a set of tools engineers and integrators could use in substation protection, automation, and control systems

IEC 61850 changes and additions

The IEC 61850 standard is a constantly evolving standard with plans to update existing parts with new editions and create additional parts to the standard. At the time of this publication the IEC 61850 documents listed in the bibliography (Annex B) were considered ([B10] through [B45]).1

Purpose

IEC 61850 has been promoted as an interoperability standard, but to date, interoperability among vendors has been achieved only at a communications level. When actually implementing the various substation functions, the user could be forced to change methods between vendors due to the flexibility and options provided for in IEC 61850. Additionally, IEC 61850 requires significant changes to the design, construction, and commissioning of a substation. Hard-wired signals are replaced by logical bits being communicated over Ethernet networks, documentation and naming conventions are distinctly different from existing substation practice, and device functionality could be assigned, and even migrate, in an operational environment. Users will also require a methodology to integrate IEC 61850 and non-IEC 61850 operational practices in their system as both approaches will have to exist side by side for many years. This recommended practice will provide a starting point for those users who would like to migrate to an IEC 61850 substation approach and establish baseline functionality to which vendors could adhere with confidence of achieving interoperability with other vendors

This guide is not intended to replace or change the IEC 61850 standard; users who implement IEC 61850 should reference the standard's sections that apply to their implementation. This guide will help users understand the sections that most affect the end users of IEC 61850 equipment and software, and gives users additional insight into other areas to consider outside of the scope of the IEC 61850 standard

This recommended practice is a starting point for a series of additional recommended practices to provide implementation details in many specific functional areas of IEC 61850. Each additional subject matter will be given an extension off the existing standard number for this guide, 2030.100.1, 0.2 … 10 … etc. (For examples, see Annex A). This recommended practice provides a general overview of the concepts and tools provided within IEC 61850 with some general considerations the user should be aware of prior to, during, and after an IEC 61850 implementation

The following are examples of specific functional areas that would be good future extensions to this recommended practice

Using generic object oriented substation event (GOOSE) messages for protection trips and permissives, and interlock control blocking

Implementing a line or feeder reclose function

Combining logical nodes to achieve a variety of protection functions

Implementing various local/remote configurations

Using sample values (SV) messages for protection and metering applications

Recommending substation and process bus network design and configuration (as a companion to the IEC-61850-90 series of reports ([B40] through [B45]) including networking topics)

Merging IEC 61850 into an existing substation automation system
