POWER SYSTEM TRANSIENT USING WAVELET TRANSFORM: A CASE STUDY

Abstract

There are numerous causes of power system transients, such as short-circuits, capacitor bank switching, switching of large inductive loads (e.g., motors and transformers), and lightning. Power system transients can pose a serious threat to the reliability of power system apparatus (e.g., switchgear, transformers, feeder cables, etc.) and sensitive loads (e.g., computers and other sophisticated electronic equipment). The main objective of this paper is to detect system transients and to analyze the power system transient waves, for predicting the hazards and making the precaution scheme for against those traveling and transient waves using wavelet transform depend on a case study.
