Installation of PMU on 330KV Buses to Displace SCADA System as a Permanent Solution to Power Grid Failure in Nigeria

Abstract

Nigeria is facing formidable challenges from an ever-increasing power demand and an ever-more complicated electricity grid, which makes modern monitoring and control systems essential. The installation of Phasor Measurement Units (PMUs) on 330kV buses is examined in this research as a potential strategic replacement for the current Supervisory Control and Data Acquisition (SCADA) systems. The goal is to improve the power grid's real-time monitoring and control capabilities while providing a long-lasting and reliable remedy to lessen the recurring problem of power grid breakdowns, with its supervisory control and data gathering capabilities, traditional SCADA systems have been essential to the administration of the power grid. But as the complexity of the power grid rises, its shortcomings in terms of speed, accuracy, and real-time data synchronization become more noticeable. Because PMUs can monitor voltage and current phasors accurately and quickly, they provide a more sophisticated and dependable option, this study explores the technical aspects of PMU integration on 330kV busses and emphasizes the real-time synchronized data collecting capabilities of these devices. In the case of grid disruptions, the deployment of PMUs enables better situational awareness, quicker fault detection, and more effective decision-making. The research also looks at the feasibility and long-term advantages of using PMUs instead of conventional SCADA systems, highlighting the possibility of improved grid dependability and decreased downtime, Given the distinct obstacles that Nigeria's power industry faces, such as frequent disruptions and outages, this study promotes the proactive deployment of PMUs as an ongoing fix for power grid failures.
