In order to meet the needs of the real-time simulation,Guizhou University has successfully developed a universal real time simulator with full autonomous property rights.The functions of the simulator are introduced,and the experimental platform of the power rapid control prototype（PRCP）is developed based on this simulator.The system composition,working principle and key test problems of the experimental platform are introduced in detail,and the emphasis is placed on introducing the modeling principle of the vector control system in the control model and the real-time switching between the pre-start circuit and the vector control system.Finally,the real-time vector control of the induction motor is realized on the laboratory prototype.The experimental results show that the experimental platform can realize the experimental function of the load simulation and closed-loop speed regulation.
