Research on the Mathematical Model of 15° Shifted Dual Twelve-Phase Non-Salient Pole Synchronous Rectifier Generator

分别在abc坐标系和dq0坐标系下建立了移15°双十二相隐极同步整流发电机的基本数学方程,推导了电机电压、磁链、输出功率、电磁转矩和转子运动方程。在MATLAB/Simulink中建立了移15°双十二相隐极同步整流发电机的仿真模型。对两路输出进行了不平衡负载仿真和试验。仿真与试验结果相比基本一致,验证了移15°双十二相隐极同步整流发电机数学模型的正确性。这为双十二相同步整流发电机运行性能和励磁控制系统的研究奠定了基础。

The basic mathematical equations of the 15° shifted dual twelve-phase non-salient pole synchronous rectifier generator were established in the abc and dq 0 coordinate systems respectively,and the motor voltage,flux linkage,output power, electromagnetic torque and rotor motion equation were derived. The simulation model of 15° shifted dual twelve-phase non-salient pole synchronous rectifier generator was set up in MATLAB/Simulink.The unbalanced load simulation and test were carried out on the two outputs,and the correctness of the mathematical model of the double twelve-phase non-salient synchronous rectifier generator was verified by the basically consistent results of simulation and test.A foundation for the research on the operation performance and excitation control system of the dual twelve-phase non-salient pole synchronous rectifier generator was laid.
