The propagation delay decides the closed-loop stability and the simulation accuracy in Power Hardware-in-Loop (PHIL) simulation. This paper calculates the closed-loop propagation delay between the real-time simulator and physical devices while performing the PHIL simulation. The test system is simulated in a Real-Time Digital Simulator (RTDS). A regenerative grid simulator acts as a power amplifier to amplify the RTDS signals. Hall effect sensors are used to feedback the physical device signals to the RTDS. The delay introduced by each component in PHIL simulation is computed and verified through experimental setup.
