NEW!IEC 61400-25-1:2017 is available as IEC 61400-25-1:2017 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.

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. 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.
