Research on Shunt APF Based on p-q and ip-iq Detection Method

分析了基于三相瞬时无功功率理论的两种检测谐波和无功电流的方法:p-q运算方式和ip-iq运算方式.并在MATLAB中建立了基于这两种方式的,相电压为220 V,功率为16 kW的有源电力滤波器的仿真模型.在仿真模型中利用求有效值的模块代替低通滤波器简化了模型的建立过程.对仿真结果进行了分析.

This paper analyzes the two methods of detecting harmonics and reactive currents： p-q theory and ip-iq theory, which are based on three-phase instantaneous reactive power theory. And a model of shunt APF, whose phase-voltage is 220 V and power is 16 kW, is built. The model is simplified by using RMS model rather than LPF. Finally, the simulation result is analyzed and it provides reference for the practice.
