摘要
日益严重的电网谐波污染,严重影响电气设备的正常工作,为了消除电网中谐波污染和减少无功的损耗,提出了一种基于PWM控制技术,采用电压型逆变器,向电网中注入补偿电流的控制策略,该策略可在电网电压畸变情况下对电网中滤波电流进行连续动态补偿,实验中利用Matlab/Simulink建立了逆变系统仿真模型,并进行仿真研究,理论和仿真实验都证明采用该控制策略可使有源电力滤波器实现更精确的控制和更理想的补偿效果。
Based on the analysis of active power filter control strategy,this paper presents PWM control technique which continuously and dynamically decompensates filter current in case of grid voltage distortion on the grid.Built and simulated the simulation model of PWM control inverter system,by experiment of simulation,in a result,approved the control strategy which can be effective compensation harmonic current.
