Abstract：AC motors are widely used in modern industry, and performance tests for motor drivers have received much attention. This paper presents a design scheme of a virtual motor system that uses a back-to-back converter instead of actual motor and its load. Since the operating conditions of AC motors are complicate, it is necessary to consider the transient processes and fault conditions. Therefore, the mathematical modeling and real-time simulation are difficult. This paper presented an asynchronous motor model considering stator winding fault, and selected quasi proportional resonant (QPR) controller for dynamic current tracking by the comparison of numerical calculation methods. Under the premise of digital control delay estimation, parameter optimization design was achieved with the goal of improving bandwidth and dynamic response capability. Simulation and experiments show that the virtual motor system can simulate port characteristics of asynchronous motor under normal conditions and the condition of stator winding turn-to-turn short-circuit fault. It can be used as an AC electronic load for the development and testing of motor drivers.
