IEC 61400-25

International standard IEC 61400-25 (Communications for monitoring and control of wind power plants, TC 88) provides uniform information exchange for monitoring and control of wind power plants. This addresses the issue of proprietary communication systems utilizing a wide variety of protocols, labels, semantics, etc., thus enabling one to exchange information with different wind power plants independently of a vendor.

The IEC 61400-25 standard is a basis for simplifying the roles that the wind turbine and SCADA systems have to play. The crucial part of the wind power plant information, information exchange methods, and communication stacks are standardized. They build a basis to which procurement specifications and contracts could easily refer.

The standard is expected to work inline with IEC 61850 standards and presently uses communication service mapping to MMS as per IEC 61850-8 standards. The communication service mapping to OPC DA and Web services are also considered for the future.

Problems in interoperability

Though IEC 61400-25 standards are expected to work as per the schema definitions of IEC 61850, it requires many entities like bitstrings which are not supported in IEC 61850 schema definitions. [ [http://iec61400-25.com/tissues.mspx?partid=1 Technical issues of IEC 61400-25] .] This raises concerns about the standard and it's acceptance. There are also deviations from base models available in IEC 61850.
