摘　　要：文章介绍12脉波整流器应用选择性有源滤波器抑制谐波电流和补偿无功,采用基于瞬时功率理论的谐波和无功电流检测方法。对有源滤波器和负荷系统进行仿真,并对仿真结果进行详细分析。仿真结果表明:基于瞬时功率理论的谐波和无功电流检测方法可以准确、实时地检测出三相电流中的任意次谐波及无功电流,有源滤波器抑制11次和13次谐波电流,并补偿无功。This article introduces selective APF to restrain harmonic current and compensate reactive power in 12-pluse rectifier by harmonic and reactive current detection method based on instantaneous power theory,simulates on active power filter and load system,and analysis of the simulation results in detail.The simulation results show that the harmonic and reactive current detection method based on instantaneous power theory can be precise and real-time detecting any harmonics and reactive current in three-phase current,APF can restrain 11 13 number harmonic current,and compensate reactive power.
