Application of PI controller based DSTATCOM for improving the power quality in a power system network with induction furnace load

Abstract

This paper presents the application of DSTATCOM in a distribution network with induction furnace load. Inductionfurnace is one of the common types of load used in industries like the steel industry. The problem with the induction furnaceload is the generation of appreciable amount of harmonic distortion. This distortion results due to the design and operation ofthe induction furnace. This harmonic distortion can even affect the performance of other loads connected in the system.DSTATCOM is a shunt connected custom power device to improve the power quality. It does so by injecting a compensatingcurrent into the power system network. In this paper, the SIMULINK model representing the application of DSTATCOM withPI controller for reducing the harmonic distortion of the distribution network with induction furnace load is presented
