有源濾波器的空間矢量控制策略仿真研究(一)

摘要：首先介紹了三相并聯(lián)型有源電力濾波器的三種控制方式，然后分析電壓空間矢量控制PWM技術(shù)原理，據(jù)此建立了仿真模型進(jìn)行仿真研究，仿真實(shí)驗(yàn)結(jié)果表明該方法動(dòng)態(tài)響應(yīng)快，開(kāi)關(guān)次數(shù)少，能很好地抑制電網(wǎng)諧波電流。 敘詞：并聯(lián)有源濾波器 空間矢量控制PWM 控制策略 Abstract：Article first introduces three control methods of shunt three-phase active power filter, then analyses the principle of voltage space vector PWM. According to the analysis, simulation model of this filter is established based on MATLAB /Simulink. The simulation results show that this method dynamic response is quick, the switch number of time is fewer, and it could well suppresses the power system harmonic current.
