【摘要】：同轴双十五相电机推进系统具有高可靠性、能容错运行、能驱动较重负载等优势,因此其在船舶电力推进中的应用具有重要意义。本文首先分析建立了十五相电机的数学模型,在此基础上建立了十五相感应电机和螺旋桨负载的仿真模型。通过广义派克变换矩阵的建立,设计了十五相电机转子磁场定向矢量控制策略,并结合同轴电机的转矩随动控制,得到了转矩随动矢量控制策略。分析了断相故障下十五相电机气隙磁场的变化,研究了切除对称分布定子相绕组的容错控制策略。通过Matlab/Simulink中的仿真模型,说明了同轴双十五相电机推进系统控制策略的有效性和容错控制策略的可行性。
[Abstract]:Coaxial double-fifteen phase motor propulsion system has the advantages of high reliability, fault-tolerant operation and heavy load driving, so its application in marine electric propulsion is of great significance. In this paper, the mathematical model of 15 phase motor is established, and the simulation model of 15 phase induction motor and propeller load is established. Based on the establishment of the generalized Parker transform matrix, the flux oriented vector control strategy of the 15 phase motor rotor is designed, and the torque following control strategy of the coaxial motor is obtained. The change of air-gap magnetic field of 15-phase motor under breaking phase fault is analyzed, and the fault-tolerant control strategy for removing symmetrical distributed stator phase winding is studied. Through the simulation model in Matlab/Simulink, the effectiveness of control strategy and the feasibility of fault-tolerant control strategy for coaxial double-15 phase motor propulsion system are demonstrated.
