Abstract

The ideal supply voltage is pure sinusoidal voltage with nominal frequency and nominal amplitude.Any variation from this is considered as a power quality event or a disturbance. One importantaspect in the field of power quality is monitoring and control of the qualitative parameters of theelectrical energy according to today’s standards. In that way, a big attention is paid to define thedisturbances and determination of procedures for their measurement. A large number of powerquality disturbances have been reported in the literature. Commercial power literally enablestoday’s modern world to function at its busy pace. Sophisticated technology has reached deeply intoour homes and careers, and with the advent of e-commerce is continually changing the way weinteract with the rest of the world. Many power problems originate in the commercial power grid,which, with its thousands of miles of transmission lines, is subject to weather conditions such ashurricanes, lightning storms, snow, ice, and flooding along with equipment failure, traffic accidentsand major switching operations. Also, power problems affecting today’s technological equipmentare often generated locally within a facility from any number of situations, such as localconstruction, heavy startup loads, faulty distribution components, and even typical backgroundelectrical noise. In this paper we analyze the and measure electric power quality to study variouseffects. The measurement results are obtained Pspice simulation. In the recent years adoption ofpersonal computers (PCs) in the field of the measurement technique offers great progress andflexibility.
