Wind turbine generator power curve fitting method and readable storage medium

The invention aims to provide a wind turbine generator power curve fitting method and a readable storage medium. The fitting method comprises the following steps: acquiring historical operation wind speed data and historical operation power data; performing data screening; carrying out interval bin separation on the screened data by taking the wind speed as an interval bin separation condition; carrying out interval bin separation on the screened data by taking power as an interval bin separation condition; calculating a plurality of wind speed section evaluation parameters and a plurality of power section evaluation parameters; eliminating a corresponding wind speed interval in the post-screening data set and eliminating a corresponding power interval in the post-screening data set to obtain a target data set; calculating the average wind speed of each wind speed interval and the average power of each power interval in the target data set to obtain a fitting data set; and fitting the fitting data set through
