摘要
在风力发电机逆变器输出的并网电流中,滤波器是保证电流质量的关键器件,良好的滤波器能有效地抑制谐波。详细分析了L、LC、LCL滤波器的结构及设计准则,并采用无源滤波的方法对LCL滤波器进行了优化,有效地提高了滤波器的谐波抑制特性。
In grid-connected current output of wind turbine inverter,filter is a key device that ensures the current quality.Good filter is able to suppress harmonics effectively.This paper analyzed the design criteria of filters including L,LC and LCL types.Moreover,the LCL filter was optimized according to passive filtering method,which effectively improves the harmonic-suppression characteristic of filters.
