Abstract

This paper proposes the combination of a static synchronous compensator (D-Statcom) based on a voltage source converter (VSC) and a harmonic filter for voltage quality improvement of power distribution network connected to nonlinear loading. The PID controller is applied to the proposed D-Statcom for stabilizing voltage amplitude at power load buses in the studied power system under changing power load. The harmonic filter is added to remove the harmonics and reduce a total hormonic distortion (THD) caused by nonlinear rectify load. Simulation results in a time domain and frequency domain are presented to show effectiveness of the proposed D-Statcom and the harmonic filter for improving voltage quality. THD coefficients satisfy the requirements when compared with IEEE Standard 519-2014 and Vietnam National Standards (TCVN) in Circular No. 39/2015/TT-BCT.
