Improvement in Distribution System Performance by D-STATCOM

Abstract

Increasing use of power electronics devices in modern power system has many power quality problems arise in distribution system like voltage sag, voltage swell, harmonics, flickering, etc. This problem largely affects the performance of distribution system. Distribution static synchronous compensator (D-STATCOM) is a device which is used for the solution of power quality problems. In this paper, voltage sag and voltage swell were generated and mitigation of the same is achieved using D-STATCOM at point of common coupling (PCC). There is 415 V distribution test system taken for the study. Simulation is carried out and results are analyzed using MATLAB Simulink software.
