Abstract: Induction furnaces are widely applied for heating and melting purpose in Iron and steel industries. Induction furnace injects significant amount of harmonics when operated under varying load conditions. This leads to power loss and affects the performance of adjacent loads. The aim of the paper is to analyze the harmonic profile of induction furnace in steel industry and suggest solution to mitigate the harmonics using a Unified Power Quality Conditioner (UPQC). The experimental voltage and current harmonics of the induction furnace are analyzed using power quality logger for a steel industry. From the experimental analysis, simulation is performed in MATLAB/SIMULINK and solutions are presented to mitigate the harmonics using UPQC.
Keywords: Induction Furnace, UPQC, Harmonics, THD.
Scope of the Article: Operational Research
