Abstract :
This paper presents the application of Dynamic Voltage Restorer in a distribution network with steel industry load. In industries like the steel industry induction furnace is one of the common types of load. Induction furnace is one of the sensitive device which is vulnerable with power quality problem, it make the major loss for industry. This paper discusses designing of induction furnace in Matlab/Simulink. Voltage sag and swell are the major power quality problem, which are eliminated by using one of custom power devices, is Dynamic voltage restorer. This paperouwsc presents protection of induction furnace from power quality problems by Dynamic voltage restorer & THD. In this paper a novel hysteresis voltage control for a DVR is proposed to improve the Power Quality (PQ). The proposed scheme has been verified through various simulations in MATLAB/SIMULINK environment. Finally, results showing that DVR protect the steel industry load from voltage sag and swell.
