A cyber-physical power system testbed for PMU based grid monitoring application

Wide area power system monitoring is a developing technology that uses advanced communication networks, and data analytics to improve grid monitoring and increase overall reliability and efficiency. This paper presents a cost-effective grid monitoring testbed (GMT), a hardware testbed for wide-area power system monitoring applications. The phasor data for testing is generated using the emulated phasor measurement units (ePMU) inside the DSA Tools software. IEEE 9 bus system has been used as the test system to demonstrate the effectiveness of the suggested strategy. The data from the phasor measurement unit (PMU) is sent to the SEL-3350 real time automation controller (RTAC) using the IEEE-C37.118 protocol. The algorithm under test is implemented within the RTAC controller. The controller output is then streamed to the SEL-synchrowave real-time power system monitoring software. On the hardware configuration, the algorithm for the center of inertia (COI) frequency reference, inertia distribution index (IDI), and angle difference with the COI angle as the reference is implemented.
