Abstract

Because the doubly-fed wind turbine contains a large number of power electronic equipment, as well as the randomness and uncontrollability of wind power generation, the wind farm inputs a large amount of harmonics while inputting active power to the grid, which brings many adverse effects to the power system. Therefore, analyzing the harmonic content of wind turbines to the main busbar of the grid is a key issue in the development of the wind power industry. The research object of this paper is mainly the harmonic propagation and coupling of the wind farm composed of doubly-fed wind turbines. By changing the wind speed and the number of wind turbines, and analyzing the harmonics by FFT (Fast Fourier Transform). The total distortion rate of the wave summarizes the variation law of the internal harmonic distortion rate of the wind farm with the number of wind turbines and the operating state.
