千米立井主排水泵电机控制系统的选择

Selection for Control System of Motor of Main Water Pump in a Kilometer Shaft

针对千米立井主排水泵的大功率电机启动和停止问题,选择具有软启动和软停止功能的固态软启动器,并比较了几种调节方法,从中选择转矩闭环控制实现电机的平稳启动和停止,最终消除水锤现象。

According to start-up and stop of big power motor of main water pump in kilometer shaft, the paper selects solid state soft starter with function of start-up and soft stopping. By comparing several regulating means, the paper selects torque closed loop control to realize smooth start-up and stopping of motor and finally eliminate water hammer.
