Cyber-physical Framework for System Frequency Response using Real-time simulation Phasor Measurement Unit based on ANSI C37.118

ANSI C37.118 protocol is broadly known for synchrophasor data broadcasting, employed by Phasor Measurement Units (PMUs). Due to the synchronous nature of this protocol, the most accurate way to use it is on physical devices and real-time testing; however, that is not always possible due to economics, resources or even uncertainties about the safety of the test. This way, hardware-in-the-loop (HIL) simulations are presumed as an adequate tool to test real devices in a flexible, cheap and safe way. Nevertheless, the implementation and configuration of this HIL environment can be troubling sometimes. This paper explains the process of building a HIL framework integrating a PMU and a real-time simulator working synchronously for fast frequency response testing on a virtual model.
