IEC 61400-25-1:2017 Released for Wind Energy Generation Systems

Untitled-1

The International Electrotechnical Commission (IEC) has released IEC 61400-25-1:2017. This standard pertains to wind energy generation systems – Part 25-1: Communications for monitoring and control of wind power plants – Overall description of principles and models and is now available on the IEC webstore.

Description: “IEC 61400-25-1:2017 gives an overall description of the principles and models used in the IEC 61400­25 series, which is designed for a communication environment supported by a client-server model.

Near and Far Field Measurements with a Vector Network Analyzer

For optimal performance in over-the-air RF systems, antennas must meet specific requirements. Performance parameters like size, wind-loading, environmental ruggedness, transmission pattern, bandwidth, and power handling capability should be considered. Methods of measuring the transmission (or reception) pattern that determines antenna gain with a VNA will be examined in this article.

Three areas are defined, that are modelled separately to ensure the scalability of implementations: wind power plant information models, information exchange model, and mapping of these two models to a standard communication profile. This new edition includes the following significant technical changes with respect to the previous edition: general harmonization of text and overview models with the other parts of the IEC 61400­25 series, harmonization of definitions in other related standards.
