摘　　要：讨论基于瞬时无功理论的各种谐波和无功检测方法在电网电压畸变情况下的适用性,独立设计有源电力滤波器对三相电力系统进行无功谐波综合补偿,并基于Matlab/Simulink仿真平台对系统进行建模仿真,仿真结果表明,所设计的并联型有源电力滤波器对系统的谐波无功综合补偿效果显著,验证了理论的正确性与可行性。The thesis mainly discusses the application of various harmonic and reactive detection methods based on the instantaneous power theory, and devises shunt active filter. Then, in order to validate the correction of various harmonic and reactive detection methods, the thesis simulates and analyzes them in Matlab/Simulink.
