三相有源电力滤波器的建模与控制策略分析

为准确分析有源滤波器的运行特点,根据系统控制策略的需要,在考虑有源滤波器输出的基础上,采用开关函数法建立了并联混合型有源电力滤波器的数学模型.提出一种前馈加双环控制的控制策略,其包括一个电感电流内环控制和一个瞬时电压外环控制.试验结果显示该系统有很好的正弦波输出波形,快速的动态响应和高精度的输出电流.

Analysis on modeling and control strategy of three-phase APF

Based on the needs of system control strategy and taking the output of active power filter into consideration,a switch function method was adopted to build the mathematical model of parallel hybrid active power filter.This paper also presents a feed forward and double loop control technology,its double loop control including a inductor current inner loop control and instantaneous voltage outer loop control.Experimental results show that the system can achieve good sinusoidal output waveform,fast dynamic res...
