摘　　要：随着可再生能源的快速发展,风电已成新能源体系的重要组成部分,大规模风电接入电网也逐步投入使用。然而,风力发电机的非线性特性和电力电子设备的广泛应用可能会引入谐波问题,对电网和电力设备运行的稳定性造成影响。通过对大规模风电接入电网的谐波影响进行详细分析,包括谐波发生机理、谐波传播路径、谐波功率流计算以及谐波滤波技术等方面的内容,为风电场的谐波管理和电网的谐波抑制提供理论与实践指导。With the rapid development of renewable energy,wind power has become an important part of the new energy system,and large-scale wind power is gradually put into use.However,the nonlinear characteristics of wind turbines and the wide application of power electronic equipment may introduce harmonic problems,which will affect the stability of power grid and power equipment operation.The harmonic impact of large scale wind power connected to the power grid is analyzed in detail,including harmonic generation mechanism,harmonic propagation path,harmonic power flow calculation and harmonic filtering technology,which provides theoretical and practical guidance for harmonic management of wind farms and harmonic suppression of power grid.
