The Comparision between Two Methods of Random Harmonic Detection in Single-phase Circuit
Because of random,stability and distribution and so on various factors,it is difficult to detect power system harmonic in real-time.The hardware requirements of amplitude separation are complex,and real-timeliness are poor.This paper introduces rotating coordinate transform,and deduces the process of the two real-time random harmonic detection,and gives the simulation based on the theory for 5th harmonic,realizes the real-time detection of 5th harmonic,and proves that both of the two methods can complete detecting random harmonic in real time by change the parameter of the hardware.But the real-time and hardware requirements of Amplitude separation are worse than rotating coordinate transform.
