This part of IEC 61400, which is a technical specification, provides a framework from which time-based and production-based availability indicators of a wind power station can be derived. It unambiguously describes how data is categorised and provides examples of how the data can be used to derive availability indicators.<\/p>\n
The approach is to apply the terms and definitions for the applied information models introduced in IEC TS 61400-26-1 and IEC TS 61400-26-2 to a wind power station.<\/p>\n
The basic approach is based on the assumption that a wind power station may be modelled as one ‘WTGS’ representing a complete wind power station. The wind power station is made up of all WTGSs, functional services and balance of plant elements as seen from the point of common coupling.<\/p>\n
It is not the intention of this specification to define how time-based and production-based availability shall be calculated. Nor is it the intention to form the basis for power curve performance measurements \u2013 which is the objective of IEC 61400-12. However, the annexes should be regarded as examples and guidelines for developing methods for calculation of availability indicators.<\/p>\n
This document also includes informative annexes with:<\/p>\n
examples of how to expand the model to more services,<\/p>\n<\/li>\n
examples of how to determine the information category for the wind power station,<\/p>\n<\/li>\n
examples of how to expand the model to balance of plant elements,<\/p>\n<\/li>\n
examples of determination of lost production,<\/p>\n<\/li>\n
examples of availability algorithms for production based indicators,<\/p>\n<\/li>\n
examples of other availability indicators,<\/p>\n<\/li>\n
examples of application scenarios.<\/p>\n<\/li>\n<\/ul>\n
