PMU Implementation Using IEC61850 Sampled Values Implemented in a CPC Platform

This paper presents the implementation of Phasor Measurement Units (PMUs) using IEC61850 Sampled Values (SV) in a Centralized Protection and Control (CPC) platform called EPICS platform. The SV-PMU microservice is developed and implemented via software on an EDGE Server, and its performance is evaluated in laboratory in both steady and transient states according to IEEE/IEC 60255-118-1:2018 standard. The evaluation tests were executed using a Real-Time Digital Simulator (RTDS). Two methods for the evaluation of the behaviour of the PMUs were implemented. The first is an evaluation in real-time using a Real-Time Automation Controller (RTAC) and the second one is an evaluation in offline mode using a Python Script. Two instances of the SV-PMU microservice were evaluated, the first one uses as signal inputs the SV generated in RTDS and the second one uses the signals generated by a Stand-Alone Mergin Unit. The tests results demonstrate the microservice's compliance with the standards, highlighting its potential to enhance the EPICS platform's capabilities as a CPC system in Digital Substations and to contributes to the deployment of Wide Area Monitoring, Protection, and Control (WAMPAC) systems in the power grid. Future work includes comparing the behaviour of SV-PMU microservice with commercial PMUs to validate its real-world applicability.
