Abstract

Power quality problems refer to a wide variety of disturbances that characterize the voltage and current at a given time and at a given location on any power system. The increasing importance of power quality in deregulated era has em phasized importance of characterizing different phenomena that occur in voltage and current. This paper focuses on capacitor switching events, which cause a temporary variation in the fundamental frequency voltage magnitude in a medium voltage industrial distribution system. The aim of the paper is to investigate the potential use of both wavelet and fast Fourier transform to identify distinctive characteristics of capacitor switching operation. These characteristics will be further utilized to determine the responsible party when transient phenomena related to capacitor switching occurs in the distribution systems. The effects of both voltage level and capacitor location in characterizing switching capacitor phenomena will be examined. Based on these studi es a general conclusions regarding switching operation will be given.
