希尔伯特-黄变换在电力系统中的应用

摘要

详细分析了Hilbert-Huang变换在电力系统谐波检测、电力系统低频振荡以及在电力系统局部电晕放电数据处理中的应用现状.最后指出,Hilbert-Huang变换克服了其他方法在信号处理中的弱点,它是一种处理非线性、非平稳信号的有效方法,有利于电力系统的信号处理.%This paper presents a detailed analysis of the applications of the Hilbert-Huang transform in the harmonics detection,low frequency oscillations as well as the local corona discharge data processing of the power system.The paper concludes that the Hilbert-huang transform overcomes the weaknesses of the other methods in the signal processing and it is an effective method to deal with nonlinear,nonstationary signals.
