Abstract
Reliability and quality are two most important facets of power delivery system. Wide use of nonlinear and electronically switched devices in distribution systems hinders the quality of supply. The problems of power quality include voltage fluctuations, flicker, harmonics, and asymmetries of voltages. Specific analysis of power quality issues and their solutions have generated tremendous amount of interest amongst power system engineers. Some of the tuned passive filters were developed to bypass specific harmonic frequencies. Since the passive filters were found to operate only over a fixed range, the attention is to be given towards compensating devices like active filtering that can effectively eliminate the harmonic currents. In this paper, analysis is carried out on an industry based induction furnace using power quality analyzer. The total harmonic distortion was found to be beyond the permissible limits as per IEEE 519 standard. MATLAB/SIMULINK model of the induction furnace is developed to analyze the reduction of harmonics using active filters. Effective reduction in source current harmonics is observed and compared based on Fourier analysis for both Hysteresis current control (HCM) and Sliding mode current (SMC) control methods.
