Design of 2000kW switched reluctance machine system

The switched reluctance machine system with high reliability and fault tolerance capability has good perspective for large power applications. The machine, the topology of the power converter main circuit and the control strategy should be taken into account as a whole for the design of the switched reluctance machine system. Four-phase 8/6 pole switched reluctance machine and four-phase asymmetric bridge power converter should be adopted in large power system with consideration of the fault tolerance capability and low voltage & current rating of power switches in power converter. The primary election of the structure parameters for 2000kW switched reluctance machine can be calculated based on the output equation and the equation of the turn numbers of phase winding. The nonlinear simulation of the system was made by taking as a whole the magnetization curves of the machine obtained by using two dimensional finite element electromagnetic field calculation, the topology of the power converter main circuit and the control strategy. The electromagnetic parameters and the structural parameters of the machine, the control parameters of the system were modified continuously until the output power and efficiency were satisfied. The magnetic flux paths of the prototype were given. The hardware-in-the-loop simulation on the controller and the system was finished based on RT-LAB simulator.
