Design and implementation of a kilowatt-scale power interface based on power hardware-in-the-loop simulation

Power hardware-in-the-loop (PHIL) has been widely adopted as an important method of virtual prototyping of electrical systems. In PHIL simulation the error (i.e., time delay and distortion) introduced by the power interface may cause severe instability issues or unacceptably inaccurate results. In the paper, modeling scheme of the PHIL simulation system, And a compound repetitive controller (RC) in power interface has been described, which has a highly static and dynamic performance. An 100kW PHIL test platform has been designed, to ensure that the overall system remains stable in operation and yields accurate results for both the software simulated system and the interfaced hardware under test. Based on this, a basic insurance and good platform is provided for the study and development of PHIL.
