计及相位影响的间谐波与电压闪变的定量关系研究
Research on quantitative relationship between inter-harmonics and voltage flicker considering the phase influence
摘要
Abstract
There is a close relation between flicker and inter-harmonics in power system.This paper further reveals the quantitative relationship between them from the perspective of signal modulation theory.On the one hand, considering the phase parameter influence, it analyzes the amplitude modulation and phase modulation effect when the inter-harmonic is superposed on the power frequency signal, and concludes that only when the amplitude modulation occurs, the inter-harmonic will cause the signal envelope fluctuation.On the other hand, the quantitative calculation formula of the inter-harmonic parameters caused by amplitude modulation wave is deduced from the flicker signal mathematical model.Simulations based on the MATLAB software verify the correctness of the conclusions.关键词
