摘　　要：研究一种改进的并联型电力有源滤波器,基于瞬时无功功率理论的谐波电流检测的ip-iq算法检测谐波电流,采用比较瞬时值的方法产生控制逆变器中开关通断的PWM信号,采用一种直接的方法获得直流侧电压,并通过一个PI调节器控制直流侧电压,最后利用科学计算软件MATLAB的动态仿真工具包SIMULINK进行了建模与仿真研究,仿真结果证明了该电力有源滤波器的有效性。An improved paralleled active power filter（APF） is presented in this paper. Harmonics current is detected by ip-iq algorithm based on instantaneous reactive power theory, PWM signal of inverter is generated by instantaneous value comparison. A directed method is employed to obtain voltage of direct current side, which is adjusted by a PI adjustor. At last, the SIMULINK tools in the software of MATLAB is used to build the model of the paralleled active power filter system, and simulation results shows it is practical.
