【摘要】 交-直-交电力机车相对于直流机车有着更优越的运行性能,但其开发却是一个慢长的过程,原因是异步电机的控制系统比较复杂,开发难度大,并且电机的控制方法会直接影响到整个机车的运行性能。结合电力牵引调速系统的特点,介绍了牵引电机在低速、高速以及弱磁条件下的控制方法,结合定子磁链定向理论提出了电机在低速下的转差计算模型,并进行了仿真研究,仿真结果表明所用方法的有效性。更多还原

【Abstract】 The performance of ACDCAC electric locomotive is better than DC electric locomotive, but the research work is a long process, since a complex control system is required. The traction motor control method in low speed, high speed and weak field range combined with the runing condition of electric locomotive is introduced in this paper. The speed different calculation model is made combining with the stator flux oriented control. The effectiveness of the proposed control method is demonstrated by simulation.更多还原
