Research on the Application of Hilbert-Huang Transform Theory to Power System

On the basis of the research results of Hilbert-Huang Transform and the application of it to the field of power system signal analysis in recent years,this paper summaries the study of power quality analysis,the harmonic identification,power system low frequency oscillations,parameter identification of synchronous machine,the partial discharge(PD) signal monitoring.The more study content is indicated in power system that is on-line analysis of low frequency oscillations,precision enhancement of parameter identification of synchronous machine,on-line monitoring of the partial discharge signal under narrow band noise,stochastic pulse.
