摘要
拟定一种新型的飞轮储能系统方案,即电机采用开关磁阻电机,并将电机转子与飞轮电池转子一体化.针对开关磁阻电机定子极绕组和支撑系统中的绕组都会产生磁场并相互影响形成耦合磁场的问题,利用电磁场分析软件分别对开关磁阻电机所产生的磁场、轴向磁力轴承所产生的磁场和径向磁力轴承所产生的磁场进行仿真对比分析.结果表明:开关磁阻电机内部磁场分布在各个情况下都符合"磁阻最小原理",能够正常工作,开关磁阻电机转矩在耦合场的影响下有所变小并使飞轮转子的速度有所提升.
A new type of flywheel energy storage system which uses switched reluctance motor and integrates the motor rotor with the flywheel battery rotor is proposed.Aiming at the problem that the stator pole windings and the supporting windings of the switched reluctance motor will produce magnetic field and influence each other to form coupling magnetic field,the magnetic field produced by the switched reluctance motor,the magnetic field produced by the axial magnetic bearing and the magnetic field produced by the radial magnetic bearing are simulated and compared by using the electromagnetic field analysis software.The results show that the magnetic field distribution in SRM conforms to the principle of minimum reluctance in all cases,and can work normally.The torque of SRM decreases under the influence of coupling field and the speed of flywheel rotor increases.
