Simulation Model of Traction Systems for CRH2 EMU Based on PSCAD/EMTDC
The high-speed railway based on electromechanical integration develops rapidly in China in recent years. In order to improve research for electrified railway, a model of AC-DC-AC electric locomotive is established using electro-magnetic transient software PSCAD/EMTDC. In this paper, a single-phase tri-level rectifier of unit power factor and its control strategy of direct transient current control method are introduced at first. And then the working principles of the voltage space vector control strategy of inverter and the vector control strategy of cage motors are analyzed. The inverter and the motors must be as a whole because of the realization of motor vector control based on SVPWM inverter. At last, a model is established and the correctness and effectiveness of the model can be verified by the corresponding theory results. The simulation model is useful for the analysis of low frequency resonance in locomotives. The results will be applied in the research of mechanics and electric coupling in high speed electrified railway.
