Frequency response analysis method based on equivalent inertia representation model of wind turbine generator

The invention relates to a frequency response analysis method based on a wind turbine generator equivalent inertia representation model. The method comprises the following steps: acquiring an equivalent inertia representation model of a wind turbine generator in a power system to the power system, and analyzing the frequency response of the power system according to the equivalent inertia representation model to obtain a frequency response analysis result of the power system. By adopting the method, the parameters of the control link and the mechanical link in the frequency response process of the wind turbine generator to the power system can be comprehensively considered to construct the equivalent inertia representation model of the wind turbine generator, so that the accuracy of the obtained equivalent inertia representation model is relatively high, and the equivalent inertia representation model is taken as reference information, so that the accuracy of the equivalent inertia representation model is imp
