摘　　要：随着风电场容量和接入电压等级的不断提高,风电场对电网的电能质量影响越来越大。分析了不同类型风电机组的谐波特性,以及在不同网架下对风电场并网点产生的谐波影响。依据风电机组实测谐波数据及风电场实际参数,使用ETAP软件对风电场产生谐波进行仿真,提出了风电场电能质量评估方法。With the increasing level of wind farm capacity and access voltage, the impact of wind farms on the grid becomes greater. This paper analyzes the harmonics generated by the different wind turbines on the grid and the measured harmonic current and voltage distortion of different wind generator types in different grid network. According the harmonic comparison of wind turbine as well as the actual wind farm parameters and IEC standard, ETAP software is used to simulate the harmonic of wind farm, and wind farm power quality assessment method is proposed.
