Abstract:
Power quality is a critical concern for both electric utilities and end-users, with the term "power quality" encompassing various disturbances within power systems. This paper addresses the growing importance of addressing harmonic distortions introduced by Variable Frequency Drives (VFDs) - devices widely employed for their efficiency and control benefits. The aim is to investigate and compare multiple harmonic reduction techniques to mitigate the adverse effects of VFD-generated harmonics. Through simulations using MATLAB/Simulink and ETAP software, the paper evaluates the effectiveness and economic viability of passive filters, reactors, multi-pulse converters, and phase-shifted drives. Results reveal distinct performance characteristics and trade-offs among the techniques, shedding light on their applicability in maintaining power quality and compliance with standards.
