Study and analysis of power quality for an electric power distribution system ??? Case study: Moscow region

摘要

In this paper, a case-study analysis of radial distribution system of Moscow region is presented. This is a part of a research project on Moscow region in Russia. The purpose of this project is to improve the power quality of an important radial distribution system of Moscow region by measuring and analysis the data of the system; and then solving the problems of power quality in this system. This paper shows the practical measurement and analysis of the radial distribution system, which has important loads with high power quality disturbances. In this study, a study and analysis of voltage profile disturbances considering over and under voltage has been provided as power quality disturbance. In addition, the voltage drops and power losses are calculated during simulation. Also, suggestions of a suitable solution to mitigate these problems have been discussed. The power distribution system has been modeled in order to simulation modeling and analysis using Matlab/Simulink.
