Reliability Assessment of Electrical Energy Distribution System – A Case Study of Port Harcourt Distribution Network
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 6
Abstract
This Paper Presents the Reliability Assessment of Electrical Energy Distribution System in Port Harcourt using the Analytical Technique and ETAP software as the simulation tool to run the reliability assessment of the System. The analysis was carried out using 2014 and 2015 historical data of Secretariat, Silver Bird, Water Works, UST and School of Nursing Injection Substations obtained from the Port Harcourt Electricity Distribution Company[PHEDC]. The results of the analysis revealed that Secretariat Injection Substation is the most reliable in the network when compared to the other four substations as it recorded system indices of ASAI: 99.90, SAIFI: 0.877, SAIDI: 8.11, CAIDI: 9.25 in 2014 and ASAI: 99.91, SAIFI: 0.873, SAIDI: 8.13, CAIDI: 9.14 in 2015. However, the overall reliability indices of the five substations under review as obtained from the analysis, revealed that the reliability of the distribution system is far below the set benchmark. System re-configuration and introduction of Photovoltaic Systems to re- supply interrupted loads at a shorter time are therefore recommended.
