摘要
主要根据本课题组近几年Hilbert-Huang变换(HHT)理论及其在电力系统信号分析领域应用的研究成果,综述了HHT理论在电能质量检测、电力系统谐波分析、电力系统低频振荡、同步电机参数辨识、局部放电信号检测等问题的应用,并探讨了HHT理论应用的进一步研究的方向:低频振荡在线分析,同步电机参数辨识精度的提高,窄带噪声、随机脉冲等干扰下的局部放电信号在线检测等问题。
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.
