The Research on the Inspect Arithmetic Based on MATLAB Instantaneous Reactive Theory

介绍了基于瞬时无功理论的谐波电流的检测方法,运用MATLAB对ip-iq运算方式的仿真模型进行了分析,结果表明该算法能很好地检测出谐波电流,达到抑制谐波的目的,最后通过仿真得出低通滤波器的截止频率选80Hz为合适。

This article introduces the inspect arithmetic of harmony wave current based on instantaneous reactive theory, analyses the emulation model of ip - iq arithmetic method with MATLAB, the result shows that this arithmetic method can inspect the harmony wave current well and restrain it, finally it gives the best cut-off frequency of low pass filter is 80 Hz by emulation.
