Abstract
Aiming at problem of noise disturbance seriously affecting voltage sag detection analysis precision,an improved al-gorithm for detecting voltage sag based on singular value decomposition and Teager energy operator was proposed which was to use Hankel matrix to realize singular value decomposition for voltage sag signal and obtain approximate signal about volt-age sag at the point of power supply after denoising.By using Teager energy operator,it was able to trace instantaneous am-plitude of this approximate signal.By simulation verification,feasibility and effectiveness of this method was proved.关键词
