Adaptability of Distribution Automation System to Electric Power Quality Monitoring In Nigeria Power Distribution Network

Abstract

The trend in Nigeria is shifting from providing electricity to consumers only but with improved quality as a result of deregulation. This paper demonstrates the adaptability of distribution automation system to electric power quality on-line monitoring using Nigeria distribution system as a case study. This paper reviews power quality problems, electric power distribution topology and monitoring quantities. The paper explains the development of program for the analysis of power quality. Sensors were incorporated at the substations for the measurement of substation voltages and line currents. The embedded system coordinates the activities of these sensors and initiates communication at regular intervals with the central server for analysis. The data backup was implemented on external card which are available for down load on monthly basis. The results reveal neglect to the issues of quality, failure to comply with regulations in some of the substations investigated. The study is expected to benefit the operator in the area of planning and improved power delivery.
