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

This paper presents the application of DSTATCOM in a distribution network with induction furnace load. Induction furnace is one of the common types of load used in industries like the steel industry. The problem with the induction furnace load is the generation of appreciable amount of harmonic distortion. This distortion results due to the design and operation of the 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 compensating current into the power system network. In this paper, the SIMULINK model representing the application of DSTATCOM with PI controller for reducing the harmonic distortion of the distribution network with induction furnace load is presented.
