Status of IEC 61400-25 Communications for Wind Turbines

The IEC TC 88 JWG 25 has published several draft documents for the second edition of IEC 61400-25:

• Part 25-1: Communications for monitoring and control of wind power plants -Overall description of principles and models
• Part 25-2: Communications for monitoring and control of wind power plants -Information models
• Part 25-3: Communications for monitoring and control of wind power plants -Information exchange models
• Part 25-4: Communications for monitoring and control of wind power plants -Mapping to communication profile
• Part 25-5: Communications for monitoring and control of wind power plants -Conformance testing
• Part 25-6: Communications for monitoring and control of wind power plants -Logical node classes and data classes for condition monitoring
