Abstract
Phasor measurement units (PMUs) are increasingly being deployed in electric power systems in an attempt to improve grid reliability and make the grid smarter through real-time wide area situational awareness, monitoring, protection and control applications. PMU-based applications require communication networks in the transmission of synchrophasor measurements from the substations to the control centres. However, the quality-of-service of these synchrophasor measurements are not guaranteed when transmitted over a global wide area network especially in the presence of non-deterministic communication network conditions. This study presents the design, development, and integration of an IEEE Std. C37.118-based co-simulation platform comprising of power system hardware-in-the-loop simulations using the real-time digital simulator interfaced to a communication network. The impact of adverse communication network conditions such as latency, packet losses, and corruption on the exchange of data using the co-simulation platform and their impact on a centralised wide area monitoring, protection, and control (WAMPAC) system was investigated with software-in-the-loop simulations. Moreover, the maximum allowable adverse communication conditions are quantified with respect to the WAMPAC applications during emergency conditions.
