Wind Power Communication
Verification report and recommendation

Elforsk rapport 02:14
April 2002

Summary

"The overall purpose of this document is to provide recommendations on do and don’ts regarding the use of IEC 61850/MMS and OPC as solutions for wind power plant communications. The report presents results from two test implementations. A version of the draft standard IEC 61850 based on the communication protocol MMS (ISO 9506) has been implemented and tested at a wind power plant in Sweden and a similar project for an OPC-interface has been conducted in Denmark....

Looking ahead the ongoing standardisation work within IEC TC88 Project Team 25 will solve most of the problems with MMS and OPC presented in the report. Similar to IEC 61850 the future wind power communication standard IEC 61400-25 will use the approach of separating the definition of information and services from the mappings to protocols. Thus, MMS, OPC and other solutions may be used to transfer the data."

Summary

A version of the draft standard IEC 61850 based on the communication protocol MMS (ISO 9506) has been implemented and tested at a wind power plant in Sweden and a similar project for an OPC-interface has been conducted in Denmark. Results and conclusions from the tests conducted in Sweden and in Denmark are documented in a separate Elforsk report, 02:14 “Wind power communications – Verification report and recommendation”. This report contains detailed descriptions on the implementation of IEC 61850/MMS in wind power plant at Gotland, Sweden. The purpose of the report is to present the technical solutions in the way of models, systems, software programs, and tools used. An important purpose is also that this material should be possible to use as basis for similar tests or pilot installations at other locations.
