摘　　要：有源滤波器是对于非线性负荷电流谐波抑制和无功补偿的一个重要手段,其中关键的环节就在于实时准确地检测谐波和无功电流。本文介绍了瞬时无功功率理论在谐波和无功电流的实时检测方面的应用。并且综合利用MATLAB中simulink环境、电力系统模块库和相关工具箱进行仿真建模。通过动态仿真,对基于此理论的两种谐波检测方法进行了对比分析,最后得出了结论。Active power filter is mainly used in restraining harmonics and compensating reactive power.The real-time and exact detection of harmonics and reactive current is essential technique. The application in harmonious and reactive current detection based on the Instaneous reactive power theory is introduced. And the modeling is carried out with simulink,power system blockset and some others toolbox. From the simulation,the two methods of harmonious detection based on this theory are analyzed. Finally,the conclusions are drawn.
