Wavelet, power system, wide area, signal, analysis


Wavelet transform has been successfully adopted in many power system fields such as power system protection, power quality and transients analysis. Typical applications include power system protection, analysis of power system transients, power quality detection and classification, etc. Development of modern computer, communication and information technologies enables design of a new class of wide area monitoring, protection and control systems. Important function of these systems is identification of the initiating disturbance event. This paper is aimed at presenting the wavelet transform usage in identification, estimation and localisation active power imbalance.
