A Comparative Study of Single-Tuned Filter and Detuned Reactor for Improve Power Quality in Microgrid

Abstract

Propose of this study is to analyze the performance of the single-tuned filter and detuned reactor to improve power quality (voltage profile, power factor, and harmonic distortion) in a microgrid. Nowadays power quality becomes the focus of the electrical company as well as commercial customer and industry. The load consists of two types, linear load, and nonlinear load. Both of them cause a reduction of power quality as voltage drop, low power factor, and harmonic distortion. Those problems can make losses of electrical usage, broken on electrical devices and can stop the production process in the industry. Single-tuned filter and the detuned reactor is the type of harmonic filter that commonly used to mitigate harmonic distortion. The harmonic filter also has benefit to improve power factor and voltage profile on the system. All filters will be simulated on ETAP to get the performance of each filter on different condition. The most dominant load in this study is a 6-pulse battery charger.
