Prospects for Situational Awareness of Power Systems Using Phasor Measurement Units (PMUs) in Nigeria

Abstract

Maintaining the stability and reliability of power grids is critical, and situational awareness (SA) is a key element in achieving such in power systems. Adopting Phasor Measurement Units (PMUs) in providing real-time monitoring and control of power systems is fundamental, sustainable, efficient, and commendable. This paper presents a comprehensive overview of PMU technology, its role in enhancing SA, and its impact on improving power system stability and efficiency. PMUs are sophisticated monitoring devices that offer high-speed and synchronized voltage and current phasors measurements: This enables power systems to be monitored and controlled in real-time. Our discussion covers the fundamental principles of PMU technology, its various applications, its implementation in power
systems, and the challenges and limitations of its use. In addition, the paper explores current and future research on PMUs and highlights the benefits of their implementation, including enhanced reliability, improved security, better power quality, and increased efficiency. Through a detailed presentation of the capabilities and advantages of PMUs in power systems, we offer valuable insights for researchers, practitioners, and decision-makers in the power industry.
