Hardware-in-loop simulation and application for high-power AC-DC-AC rolling mill driving system

Hardware-in-loop (HIL) Simulation is an excellent verification tool for controllers operated under high voltage & power conditions. In this paper, aim to high-power AC-DC-AC rolling mill driving converter system, a HIL simulation platform based on dSPACE simulator was built. With the real-time simulator, a virtual field operation environment was constructed for converter controller debugging and test, which could completely satisfy the requirements of AC-DC-AC rolling mill driving system products functions and performances verifying, reducing the products development depending on test resource greatly. The simulation platform has applied in rolling mill converter development, shortening the products development cycle and decreasing the cost largely.
