Analysis of Power Quality Disturbances in Industrial Distribution System

Abstract

Due to the increased globalization, industrial revolution is happening at a rapid pace,the modern day insustial loads comprises of different power converters,electromechanical devices, furnaces, electronic equipment and computing devices to perform various process according to the needs of industrial applications, stochastic and non linear loads used to perform the desired operation introduces variety of power quality disturbances to the grid and inturn distracts the operation and performance of the associated loads within the industry,the power quality issues like harmonics,interharmonics, voltage sag and voltage flicker are commonly observed phenomenon, in this paper an attemped is made to model and simulate the industrial loads and analyse the impact of the power quality disturbances in an interconnected industrial distribution system.
