Abstract
This paper presents a platform for testing wide area
monitoring system (WAMS) applications in real time with a
Hardware-in-the-Loop (HIL) approach. The power grid dynamics
are emulated by performing real-time phasor simulations. Voltage
and current phasors can be streamed to external systems based on
the standard IEEE C37.118-2011, recreating synthetic
synchrophasors. Moreover, phasors can be transformed into timedomain
quasi-sinusoidal signals and transferred via a low-latency
fiber optic connection to a 200 kW high-bandwidth grid emulator.
The grid emulator can amplify the voltage and current signals,
allowing Power Hardware-in-the-Loop (P-HIL) testing of physical
hardware components. A graphical user interface has been
developed to facilitate the interactions with the real time
simulation and for better visualizing the power system dynamics.
Two WAMS applications for assessing voltage stability margins
and for detection of power oscillation are implemented and tested
as examples. These examples demonstrate that the framework is a
suitable platform to test WAMS applications in power systems
