大亚湾核电站核燃料运输吊车桥架驱动双控制器闭环控制

Bridge Balance Control of Fuel Handling Machine for Daya Bay Nuclear Power Plant

为了提高大亚湾核电站换料大修的工作效率,对核燃料运输桥式吊车桥架两侧的电机驱动方式进行了技术改进。本文分析了原有核燃料运输桥式吊车所存在的问题,重点介绍了改造方案的特点和实施情况。改造后的桥式吊车驱动采用双控制器同步控制2台电机运行,采用可编程控制器(PLC)协调2台控制器工作,很好地解决了桥式吊车在高速和远程下的同步问题。

In order to improve the outage efficiency of Daya Bay Nuclear Power Station, it is necessary to modify the motor-driven types of the fuel handling machine bridge, This paper focuses on the problems for the existing bridge crane for nuclear fule transportation and the characteristics and implementation of the new solution. After modification, the bridge crane was driven by two motors controlled by two separately motor drives, and a PLC was used to balance the operation of the two motors. This solution solved the synchronization problem under the high speed and long traveling distance for the bridge crane.
