摘　　要：采用异步电机发电,是解决偏远地区用电及车载独立电源系统问题的有效辅助手段。大功率内燃机车带动牵引电机运行时所需负荷电流变化大,另一方面原动机转速范围大也会影响发电机的输出电压,发电系统输出恒定的电压直接决定行车安全与否。本文采用转子磁场定向的异步电机发电系统的矢量控制对其输出电压稳定性进行调节控制,针对动态电压响应过慢问题,采用负载预估前馈控制来进行电流补偿,以加快系统响应速度,经过仿真实验最终将该控制算法用于某一牵引电机的调速控制仿真,结果表明,所构建的异步发电系统能发出恒定的电压,对于转速及负载变化有较强的抗干扰能力。The use of asynchronous motor to generate electricity is an effective auxiliary means to solve the problems of power consumption and independent power supply systems in remote areas.The high-power diesel locomotive requires a large change in the load current when driving the traction motor.On the other hand,the range of the prime mover’s speed is large,which also affects the output voltage of the generator.The constant voltage output of the power generation system directly determines whether the vehicle is safe or not.In this paper,the vector control of the rotor-field-oriented asynchronous motor power generation system is used to adjust and control the output voltage stability.For the dynamic voltage response is too slow,load estimation feedforward control is used to accelerate the system response speed.Finally,the simulation experiment is carried out.Finally,the control algorithm is applied to the speed control simulation of a traction motor.The results show that the constructed asynchronous power generation system can emit a constant voltage and has strong anti-interference ability for speed and load changes.
