Wind power plant template machine selection method

Abstract

The invention provides a wind power plant template machine selection method, and belongs to the field of wind power plant theoretical generating capacity calculation. The method comprises the following steps: acquiring wind speed data of each wind turbine generator in a wind power plant; calculating a wind speed Weibull distribution curve parameter of each wind turbine generator set; the wind speed data of each wind turbine generator set is normalized after dimensionality reduction, the wind speed Weibull distribution curve parameter of each wind turbine generator set is normalized, and an input variable matrix of a wind power plant grouping model is constructed by using a normalized result; clustering the input variable matrix of the wind power plant grouping model according to the determined optimal grouping number of the wind power plant units to obtain a grouping result of each wind power plant unit in the wind power plant; and selecting the template machine of each group by using a correlation analysis method to obtain a template machine selection result of the wind power plant. According to the method, the wind power plant sample plate machine is selected through the base clustering algorithm, the reasonability and representativeness of sample plate machine selection can be improved, and the accuracy of power generation calculation can be improved while the calculation efficiency is guaranteed.

Description

technical field [0001] The invention belongs to the field of theoretical power generation calculation of wind farms, and particularly relates to a method for selecting a wind farm model machine. Background technique [0002] In view of the problem of wind curtailment and curtailment, it is necessary to scientifically and efficiently evaluate the theoretical power generation and curtailment levels of the entire field, so as to accurately grasp the operation status of the wind farm, and on this basis, take corresponding technical measures to reduce the phenomenon of wind curtailment, thereby Reduce the waste of wind energy resources. [0003] At the end of 2012, the State Electricity Regulatory Commission issued the calculation method for the abandoned wind power of wind farms, and promoted the model machine method to calculate the abandoned wind power in China. The model machine method can accurately count the abandoned wind power, but whether the model machine can be reason...

Problems solved by technology

This method can not only reflect the representativeness of a single machine, but also avoid the complexity of calculating one by one, but this method cannot make the difference between the classified clusters the smallest, and the difference between different types of clusters is the largest, so it cannot be more effective. Produce a more representative model machine to calculate the theoretical power generation of wind farms and wind power curtailment
