| 摘 要： | 针对并联型有源电力滤波器产生的补偿电流应实时跟随其指令电流信号变化的要求,提出了一种基于滞环比较器的瞬时值比较方式,其电流控制采用跟踪型PWM控制方式。该方式应用于电压源型变流器为主电路结构的并联有源电力滤波器中,对三相四线制系统中非线性负载的谐波和无功电流有理想的补偿效果。着重给出了选取滞环宽度的理论分析和仿真模型,设计了一套三相四线制并联有源滤波器实验装置。仿真和实验结果证明了所选取控制方法的可行性和有效性。

| Abstract: | An instantaneous value comparison method based on hysteresis comparator is proposed for the requirements of compensation current generated by parallel active power filter should be changed to follow their current instruction signal real-time,the use of current control is the tracking PWM(Pulse Width Modulation) control mode.The mode is applied to the parallel active power filter with the main circuit structure of voltage source converter for the three-phase four-wire system in nonlinear load harmonics and reactive current to have a desired compensation results.The theoretical analysis and the simulation model of selected hysteresis width are given,and a set of the experiment installation of three-phase four-wire parallel active filter is design.Simulation and experiment results prove the feasibility and effectiveness of the selected control method. |
