| 摘 要： | 为解决传统单相系统瞬时谐波电流检测中难以滤除100Hz谐波的问题,提出一种基于移相对消的改进 型谐波电流检测方法,从原理上消除了基波提取中的2次谐波,在很大程度上降低了低通滤波器(LPF)的设计难度.这里首先介绍了基于锁相原理的传统谐波电流检测方法,在此基础上提出了基于移相对消的改进方法,并通过数字仿真和实验对二者特性...

| Abstract: | In order to solve the problem that the 100 Hz component is difficult to be filtered out with traditional in-stantaneous harmonics detecting method in single phase system,an improved harmonic current detecting method based on phase-shifted cancellat.This method can eliminate the second wave of fundamental wave extraction theoretically,so it makes the design of the low-pass filter easier.The traditional method of harmonic current detecting is firstly intro-duced and then an improved method based on phase-shif... |
