摘要 在双馈风力发电变流器中,网侧变流器与电网之间需要串联滤波器来抑制开关频率周围的电流纹波。提出了一种新型的LCL滤波器设计方法,该方法考虑了滤波电容的变化对LCL滤波器整体性能的影响,对系统进行稳定分析,给出了合适的网侧变流器电流环比例增益。仿真结果验证了该设计方法能够用较低的总电感值,获得很好的高次谐波滤除效果。 In double-fed wind power converter, the series filter between grid side converter and gird was needed to inhibit current ripple around switching frequency. A new type of LCL filter design method was raised. The impact of change of filter capacity on integral performance of LCL filter was taken into consideration in the method. Stability analysis was carried out for the system and the proper grid side converter current loop proportion gain was given. Simulation result has verified that the design method can use lower total inductance value to obtain very good high order harmonic filtering effect.
