GB/T 38174-2019 (Wind energy generation systems - Availability for wind power stations) is available as an English-translated PDF.
GB/T 38174-2019 — This standard provides a calculation framework for the time availability and service output availability performance indicators of wind farms, and describes the data categories. Method, and an example of applying the data to calculate the availability index is given. This standard applies the terms and definitions in GB /Z 35482-2017 and GB /Z 35483-2017 models to wind farms. The basic method of this standard is to assume that the entire wind farm can be modeled as a single wind turbine to represent the entire wind farm. The wind farm is an aggregate of all wind turbines, functional services and supporting facilities of the wind farm at the grid connection point. The purpose of this standard is not to specify calculation methods for time availability and service output availability, nor to measure power curve performance. Provide evidence; see IEC 61400-12 for power curve measurements. However, its appendix should provide detailed examples and instructions for the calculation method of the availability index. south. The informative appendix of this standard includes. * Examples of extending the model to more services; * Examples of wind farm information categories; * Examples of extending the model to supporting facilities of wind farms; * Calculation example of service output loss; * Example of service output availability algorithm; * Examples of other availability indicators; * Application examples.
