缺相容错运行是多相电机重要优势之一.针对舰船十五相新型感应推进电机不对称缺相故障,在容错电流有效值不超过额定值的前提下,以输出转矩最大为目标,计算了容错电流并提出相应的容错控制策略.所提缺相容错控制采用与电机正常运行时相同的数学模型及解耦变换矩阵,无需重新计算电机参数,可以尽量少的改动容错控制策略.通过对一台45kW十五相感应电机不同缺相故障进行容错控制试验,验证了容错电流计算及控制方法的有效性.“,”The superior fault-tolerant capability is one of the most significant advantages of the multi-phase induction machines. The post-fault currents with the maximum torque were optimized of a fifteen-phase induction machine under asymmetrical fault condition. The corresponding fault-tolerant control strategy was proposed. The fault-tolerant control was based on the normal decoupling transformation and machine mathematical model, thus the machine parameters need not be recalculated and the reconfiguration of the controller was minimized. Different open-circuited faults of a 45kW prototype 15-phase induction machine were analyzed and tested. The good agreement between calculated and experimental results verifies the accuracy of the proposed fault-tolerant control.
