| 摘要: |
| 根据对LCL型滤波器元件参数的约束条件的分析，提出在双馈风力发电机（DFIG）系统的网侧变换器（GSC）侧连接星形LCL型滤波器，在转子侧变换器（RSC）侧连接三角形LCL型滤波器，并以2.5 MW的DFIG为例，给出了各滤波器的参数。仿真结果表明，采用了提出的LCL型滤波器设计方法后，DFIG系统的GSC侧总谐波畸变率（THD）下降为1.70 %，RSC侧总谐波畸变率下降为1.64 %，滤波效果远优于L型滤波器。 |

| Abstract: |
| The constraints of LCL filter parameters are analyzed and it is proposed to connect a star-type LCL filter to the GSC（Ｇrid-Ｓide Ｃonverter） of DFIG（Doubly Fed Induction Generator） system while a delta-type LCL filter to its RSC（Rotor-Side Converter）. The parameters of both filters for a 2.5 MW DFIG are given as an example. Simulative results show that，the THD（Total Harmonic Distortion） at the GSC side of DFIG system with the proposed LCL filters is reduced to 1.70 % while that at its RSC side is reduced to 1.64 %，which are much lower than those of DFIG system with L filters. |
