目前用于电网电流谐波补偿的电器设备，主要以PWM整流器为主。基于PWM整流器的电源产品只能被动地减小自身向电网输出的谐波电流，而对电网中业已存在的电流谐波污染束手无策。为了解决电网中电流谐波污染以及相关联的电压波形失真问题，采用基于SRM（智能整流模块）技术对电网电流谐波进行补偿。仿真结果表明，基于 SRM 的电力电子装置在从电网吸取电流并在向负载供电的同时，还能对电网电压的波形进行补偿，使电网电压波形接近正弦波形。

PWM rectifier is the major electrical equipment for current harmonics compensation in power system. The power supply products based on PWM rectifier can only passively reduce its output harmonic current,and fail to cope with the existing harmonic pollution in power system. In order to solve the problems of current harmonic pollution and associated distortion of voltage waveform,a new method based on the SRM(Smart Rectifier Module)technology has been proposed to compensate for the current harmonic wave in power system. The simulation results show that,while drawing current and supplying the load to the grid,SRM-based electronic devices can also compensate for voltage waveform, which makes the voltage waveform close to sinusoidal waveform.
