Power Quality and Reliability improvement with Voltage Control for Radial Distribution Networks in Ghana

摘要

This work addresses the 1ssue of power quality and reliability problems caused by voltage sag and swell with precise voltage control test system for medium-voltage radial distribution networks.The installation of distribution static synchronous compensator is analyzed and the steady state performance of both capacitor bank and DSTATCOM 1S determined and compared for various values of voltage sag and swell,loading level and system fault level.All simulations are performed and analyzed using PSCAD/EMTDC simulation software.Simulation results are presented to show theaccuracy and optimum performance of each device as a potential power quality and reliability improvement.
