摘　　要：为减小单绕组磁悬浮开关磁阻电发电机(SWBSRG)保持悬浮时绕组的铜耗,以及解决励磁不平衡时续流发电区间悬浮不可控问题,提出了一种新的悬浮发电控制策略。该控制策略可降低悬浮过程中绕组的铜耗。并通过对悬浮、励磁、发电区间的划分和区间时长的推导来解决续流发电区间悬浮不可控问题。通过Simplorer和Maxwell的联合仿真验证了此种低铜耗悬浮发电原理的正确性以及转子径向位移具有较好的悬浮收敛性,并通过反馈控制励磁电流来实现对输出电压的良好控制。In order to reduce the single winding bearingless switched reluctance generators（SWBSRG）to keep the suspension winding copper loss,to solve the unbalanced power excitation interval to be not controllable suspension after flow problem,this paper proposes a new control strategy for suspension and electricity generation.This control strategy proposed can reduce the copper loss of the suspension.Through the division of the suspension,excitation,generation interval and interval length,we can solve the problem that suspension is uncontrollable in electricity generation interval.Through the co-simulation of Simplorer and Maxwell proved that the suspension and electricity generation with less copper losses principle is correct and the rotor radial displacement has better suspension convergence,by the excitation current feedback control it achieves good control of the output voltage.
