摘　　要：对广义有源电力滤波器和广义无功功率理论在广义有源电力滤波器参考电流检测中的应用问题进行了研究,介绍了广义有源电力滤波器的主电路、工作原理以及参考电流检测方法,给出了仿真结果.理论分析和仿真结果显示,使用六桥臂PWM变流器实现广义有源电力滤波器的主电路,基于αβ0正交变换的广义瞬时无功功率理论检测广义有源电力滤波器的参考电流,使广义有源电力滤波器具有功能强、性能好以及参考电流检测实时性好、精度高、实现容易等特点.A generalized active power filter（GAPF） and the application problem of generalized instantaneous reactive power theory in the referential current detection of GAPF are studied. The main circuit, operating principles and referential current detection arithmetic of a GAPF are introduced and the results of a simulative experiment on the GAPF are given. Here, a three double-bridge ann PWM convertor is utilized to actualize the main circuit of the GAPF and a generalized instantaneous reactive power theory based on the αβ0 orthogonal transformation is employed to detect the referential currents of the GAPF. Through the theory analysis and computer simulation, it is shown that the proposed GAPF has the characteristics of many functions, favorable performances and so on and there are advantages of favorable real time, high precision and easy realization etc in the detection of the suggested referential currents.
