摘要
谐波电流检测的准确性是有源滤波器可靠运行的首要环节.在传统谐波检测算法的基础上采用一种基于三相瞬时无功功率理论的改进的ip-iq算法,并在MATLAB/Simulink下进行建模仿真.结果表明,该谐波电流检测算法能够及时、精确的检测到负载产生的谐波电流,从而使控制装置产生的补偿电流能够精确得跟踪指令电流,最终达到精确补偿负载谐波的目的.
The accuracy of harmonic current detection is the most important part of an active power filter to work reliably.On the traditional harmonic detection algorithm,a improved ip-iq algorithm was improved based on three-phase instantaneous reactive power theory and conduct simulation under MATLAB/Simulink.Simulation results show that the algorithm can detect the harmonic currents timely and accurately,so the compensation current generated by the control unit can track the command current accurately.Finally,load harmonics was compensated accurately.
