摘要
基于两相电流控制模型 ,推导出了并联电压型有源滤波器输出电感值的估算公式 ,并通过对感性负载、对称整流负载及不对称整流负载等条件下补偿性能的仿真分析 ,验证了该公式的可行性 .采用本方法选取电感值 ,可获得良好的补偿性能 ,补偿后的总谐波畸变率小 ,动态补偿响应速度快 ,暂态过程冲击小 .
This paper derives a formula to estimate the output inductance value of a parallel active power filter on the basis of two_phase current control strategy. The formula is proved to be feasible through simulation analyses of compensation performances of the inductancc load, rectifier load and asymmetry load. Inductance value selected by this method is suitable for filter which has good compensation performances. After compensation, total harmonic distortion is low, dynamic response is fast and transient impulsion is low.
