摘　　要：双馈异步风电机组(以下简称DFIG)和电压型PWM变流器(以下简称变流器)组成的风电机组在运行过程中极易产生对电网质量有害的谐波,经过理论分析和实践,发现了产生谐波的主要原因,提出了解决风电机组系统谐波的有效措施。同时提供了一组由变流器供电的DFIG谐波检测数据,对DFIG的设计和电网谐波的抑制及检测具有一定的参考意义。The doubly-fed induction wind turbine (hereinafter referred to as DFIG) and voltage-type PWM converter (hereinafter referred to as the converter) consisting of wind turbine during operation are easy to produce harmful harmonics on the grid quality. Through theoretical analysis and practice, we got the effective measures to solve the wind turbine system harmonics. At the same time, a set of harmonic detection data was applied, which has a certain reference value for DFIG design and the grid harmonic suppression and detection.
