    Comparative analysis of the reliability assessment of commercial and residential feeders in the power distribution utility of Nigeria
    (e-Prime - Advances in Electrical Engineering, Electronics and Energy, 2024) Adesina, Lambe Mutalub; Ogunbiyi, Olalekan; Jimada-Ojuolape, Bilkisu
    Reliability studies serve as valuable tools for assessing and optimizing system performance. Utilities with higher reliability indices are more likely to achieve break-even points due to significantly reduced downtime. This paper explores a comparative assessment of two 11 kV feeders supplying electricity to residential and commercial customers, addressing concerns about distribution system reliability in Nigeria and its impact on the country’s GDP. The study involves a comprehensive reliability analysis, utilizing a flowchart to outline procedural steps and employing the ETAP Software program for data analysis collected over a one-month period from a power utility company. The data encompass operational parameters such as day-hourly consumption, outage records, and network equipment data. Results indicate higher reliability indices in the commercial feeder compared to the residential feeder, with the Customer Average Interruption Duration Index (CAIDI) being lower in the com- mercial feeder. The research underscores the significance of reliability assessment in improving operational efficiency, facilitating maintenance planning, and enhancing customer satisfaction.

    Effect of Capacitor Bank Installation in a Medium Voltage (MV) Substation
    (International Institute for Science, Technology and Education (IISTE), 2017-01-01) Adesina, Lambe Mutalub; Ebere Iheanyichukwu
    Several medium voltage substations, often called 33/11kV injection substations in Nigeria, are being run in electric utility companies without installing capacitor banks. Research has shown that the inclusion of capacitor bank improves system power factor and efficient running of the power system. This paper presents a brief description of the theory of power factor and its importance in achieving power system control and stability. Possible implications of substations without capacitor bank installations were also itemised. A schematic diagram of Ajangbadi 2X15MVA 33/11kV injection substation in Eko Electricity Distribution Company, Nigeria, is presented as a case study. A flowchart of the algorithm used to determine substation and network load parameters was developed and implemented. All results obtained and the necessary conclusions are presented.
