| Abstract: | It introduces the ip-iq harmonic detecting method based on the instantaneous reactive power theory, and further discusses the positive sequence, negative sequence and reactive detecting of random number harmonic in the single- phase, three-phase and three- wires, three- phase and four- wires. Then this paper discusses the implementation of low pass filter and phase lock loop in detail. In the end, some simulation and experimental results are gived to prove the validity. |

| Keywords: | instantaneous reactive power theory harmonic detecting method low pass filter phase lock loop digital implementation |
