Abstract:
There is a growing emphasis on enabling modernization of traditional power systems by integrating new features and smart technologies to facilitate optimization of grid operations. Phasor Measurement Unit (PMU) is the future of electrical grids employing the use of synchronized phasors to provide system engineers with dynamic supervisory control and post fault analytics. Its exceedingly superior reporting rate compared to contemporary monitoring technologies enables better decision making and rapid actuation of protective equipment. This paper discusses the design of a real-time monitoring system that employs the use of a non-DFT based three phase PMU in accordance with the measurement requirements set in IEEE Standard C37.118.1. The reference for time stamping is Global Positioning System's 1 pulse per second signal. The processors used are Raspberry Pi 3 for the development of PMU and Windows Core 2 Duo computer for the development of PDC. Numerical computing platform, MATLAB is used for plotting of real time data. The paper also discusses previous models of PMU made by the undergraduate students of Electrical Engineering.
