摘要
针对架线式矿用电机车负载变化频繁、供电波动较大、工作环境恶劣等具体工程实际问题,提出了具有最大转矩输出能力的改进型转差频率控制方法及重载转矩补偿和母线电压补偿措施,研制了DC550V/300KW实验样机。仿真和实验表明,驱动系统在启动和拖动过程均具有较大的转矩输出能力和良好的动态响应特性,提高了牵引性能和系统的可靠性。
The load and volatile electricity of mining locomotives is frequently changes with poor working conditions.A maximum-torque slip frequency control method with maximum torque output and overload torque compensation and bus voltage compensation measures is proposed.A DC550V/300KW experimental prototype is developed.The simulation and experiment tets show that the drive system in the process of start-up and speeding with heavy loads has stable torque control effect and good dynamic response.The traction performance and reliability of the system is improved.
