Abstract
The test platform of actual electrical machines and their associated mechanical loads can be replaced by the motor emulator system based on inverters. The system is convenient for the tests of frequency conversion driving and provides guidance for control optimization. Fitting mechanical load model is a key technology of the system ,in order to simulate asynchronous motors and their loads,a current closed-loop vector control strategy based on virtual rotor flux orientation was proposed. The control strategy adapts to arbitrary input voltage and guarantees the speed and accuracy of port current tracking. Moreover,it meets the requirements of the relationship between voltage and current of the motor emulator in both steady and transient state. No-load starting,sudden loading and three phase unbalance of induction motor had been simulated,and the results of simulation verifiy the validity and feasibility of the scheme.关键词
