During power generation and In the field of power transmission, a large number of interactive interfaces related to energy or information have emerged from many related parties. Figure 1 clarifies the relationship between power generation and asset management Related internal and external factors, and put forward a series of related terms. This standard provides the division of specific time periods by building an information model. Method for allocating different information categories. When calculating the availability of wind turbines, the model provides a basis for how to allocate time. Figure 1 Related parties of wind farm data In order to explain the availability, service life, maintenance, and maintenance interval standards of wind turbines and components, this standard defines wind Generic terms for power plant systems, environmental constraints, and calculations of energy availability measurements for wind turbines. Wind Turbines A group contains all the devices between it and the access point 1). The availability is related to the time and/or power generation of the wind turbine, and at the same time Taking environmental factors into consideration. These environmental factors include wind and other weather conditions, as well as the state of the power grid and substations. In addition, this standard also Provides the terminology required for performance indicators related to the availability of wind turbine power generation. In this standard, basic information categories are indicated by double quotation marks, and optional information categories are indicated in bold. 1) See IEC 60050-415..1999,415-04-01 for definitions. Wind power generation system availability1 ScopeThis 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.2 Normative referencesThe following documents are essential for the application of this document.
