摘要:
针对地铁列车牵引系统中的交流牵引电机最小能耗问题,提出了一种最大转矩电流比控制目标下的励磁电流给定策略,该策略可使电机高效平稳运行于恒转矩区、恒功率区和恒电压区。根据牵引电机在不同转速下的牵引特性曲线,充分考虑电机本体的最大电压、最大电流的限制和磁场电流对互感的影响,设计出优化的励磁电流给定,使得输出最小的电机电流获得同样的转矩性能。仿真和试验结果证明电机在全速范围内可稳定运行,并且电机在各速度点给定转矩的情况下,输出电流比设计值小。
Abstract:
Aim at the problem of traction motor minimum energy consumption for metro vehicle, a field current given strategy based on maximum torque per ampere control target was proposed, which could make the motor operate at constant torque range, constant power range and constant voltage range smoothly and effectively. According to the traction characteristics curve under different speed of the motor, and considering the max voltage and current limitation and the field current influencing on mutual inductance, the optimized given field current control was designed, which could obtained the same torque performance with the minimum motor current and improve motor efficiency. Simulation and experiment showed that the motor could operate at the whole speed range stably, practical current of which was lower than the designed.
