Investigations on wavelet based power signal disturbance identification and classification

Abstract

The nature of the loads connected to the power system has newlineundergone gradual changes from the conventional applications of lighting newlineheating and motor load to highly sophisticated and sensitive electronic loads newlineAs a result the quality of power supply has deteriorated The reliability of the newlinepower supply also has become poor Hence the area of power quality has newlineemerged in to an important field The accurate and fast determination of newlinesignal parameters plays a vital role in designing the power quality algorithms newline newline
