A novel technique for shaping source current waveform using electronic circuit

Abstract

All over the world, utilities of electricity and end users of electricity are becoming increasingly concerned about the quality of power. Power quality has become one of the most prolific buzzwords in the electric power industry since the late 1980s because widespread studies on harmonics and its impact. Most of the electrical devices are will fail or will be malfunctioned when exposed to one or more power quality issues. In this paper various reasons for power quality issues are discussed also specially focusing on a new method to minimize distortion with the help of a non critical load. During the entire cycle of operation, the critical load and non critical load are triggered alternatively to compensate the imbalance in the current waveform. Simulation is done using PowerSIM simulation environment. In this paper various reasons for power quality issues are discussed with particular focus on a new method to minimize one of the major causes of distortion. Traditional methods to reduce the causes for power quality issues are mentioned. A new control technique is used to control critical loads. Simulation is done using PowerSIM simulation environment.
