摘要:
当原有机车牵引用的感应电机利用永磁同步电机代替时,由于永磁同步电机在经过分相绝缘子时永磁体的存在会产生高的反电动势使断电后重投瞬间出现不可控冲击电流。针对该问题在永磁同步电机三相瞬态数学模型的基础上,对其瞬态冲击电流产生原因进行了分析研究,该分析过程主要是建立在带谐波的P W M调制波的基础之上。根据分析结果,对重投时的控制条件和控制方法进行了探讨性研究,如对给定转速进行了一定的限制,对逆变器重投瞬间的电压幅值和相位进行了一定的控制,利用滑模控制的强鲁棒性和抗干扰性代替了PD控制。最后,设计了一种使重投瞬间冲击最小的滑模控制系统。经实验和仿真对比分析,验证了瞬态冲击产生机理分析的有效性及设计的控制系统在抑制断电-重投瞬间电流冲击强度的积极作用。
Abstract:
 if the original asynchronous motor of engines is replaced by permanent magnet synchronous mo­tors, the unpredictable surge current will emerge when power down-rejoining on. The causation iback EMF of permanent magnet arising from PMSM when engine is pasing the switching phase insulator. Aiming at above-mentioned problems, the reasons was analyzed of causing transient surge current based on three-phase PMSM transient mathematical model in the process of power down-rejoining on. The analyzing process is based on the PWM voltage which takes voltage harmonics into account. According to the analyzing results, the control strategies and conditions during the power down- rejoining process were dis­cussed. The control conditions include the given speed, the voltage amplitude and phase of inverter and so on. A control system was designed that makes the transient surge current minimum in the process of power down-rejoining on. By the comparative analysis of simulations and experiments, the validity of analysis for transient surge current mechanism is verified, and the positive function of optimizing control system is il­lustrated when reducing the transient surge current in power down-rejoining on.
