摘要

结合已有的工程经验

分别从整个混合滤波系统和有源部分的电压型逆变装置2个层面开展谐波电压对并联混合型有源滤波器影响的分析

得出谐波电压可能导致系统谐振以及直流侧电压抬升的结论。在此基础上

提出在开始设计混合滤波系统参数时就考虑相关参数的配合以避免与系统发生谐振并尽可能降低有源部分谐波分压

同时对直流侧电压采取合适的控制策略或设置有效的泄放回路以防止其飙升等方法来有效消除谐波电压对装置性能的影响

最后通过仿真实验进行了验证。

Abstract

Based on the past engineering experiences

the influences of background harmonic voltages on the shunt hybrid active power filter are studied by analyzing the current canceling system and active inverters. It is found that harmonic voltages may cause system resonances and/or DC voltage rising for active power filters (APFs). Based on these results

two methods are presented to minimize the influence of harmonic voltages. The first one is by selecting suitable system parameters to void resonances and therefore minimize the harmonic voltage of APF. The second one is by controlling DC voltage or using purpose designed return circuits. The simulation results show that the effectiveness of the proposed methods.
