Reliability Indices Evaluation of Distribution Networks for Automation

ABSTRACT

The world electric power systems are fast becoming smart, with the grid possessing capabilities that enable it self-heal in the case of device failures. If the Nigerian distribution networks are automated, it would go a long way in sustaining the ailing power grid. For automation to be carried out in the network, certain features would be enhanced through integration of high-speed, reliable and secure data communication networks to manage the complex power systems effectively and intelligently. This work presents the reliability evaluation of power distribution networks in Rivers State, Nigeria. Certain reliability indices were calculated using data obtained from Port Harcourt Electricity Distribution Company (PHEDC), Ahoada Business unit and Agogo Services, Egi Power Distribution network. The Performance, reliability and quality of service of the networks were investigated. The investigation revealed the system had an average availability of 64.44% for Ahoada and 74.10% for Egi as against the ASAI goal of 99.99%, this values were obtained for Egi Network despite the fact it was supplied by a private turbine signaling that to enhance distribution network reliability, increased investment in power production was required and as such an indigenous automated distribution system that can remedy the unreliable local distribution system was suggested.
