Since many power electronics equipments and nonlinear loads were accessed, more and more harmonics and inter-harmonics occurred in power system. But when the analyzed signal contains components with frequency close to each other, precise analysis can not be made by traditional harmonics analysis methods such as interpolating windowed FFT method. In this(More)
The voltage flicker which might bring out lighting equipments glitter and images distortion, make people's visual fatigue and adversely affect people's daily lives is caused by the great increase of shocking and nonlinear loads in the power system. In this paper, the causes, detection and measurement of the voltage fluctuation and flicker are analyzed,(More)
