Research on an estimation method of power generation loss of the fault wind turbine based on correlation analysis

In this paper, a new method for estimating the power generation loss of a fault wind turbine is proposed. In this method, the wind speed is estimated and the estimated value of the loss of power generation is given by combining the actual output power characteristic curve of the wind turbine. In the wind speed estimation, the correlation analysis is introduced, and the normal operation of the wind speed of the fault fan is selected, and the regression analysis method is used to obtain the estimated value of the wind speed. Based on the estimation method, this paper presents an implementation of the method in the monitoring system of the wind turbine, and verifies the effectiveness of the proposed method.
