摘要
宜都换流站内水冷主循环泵通过变频器进行控制,而龙泉、江陵换流站则通过软启动单元进行控制。由于变频器故障,宜都换流站已经出现过数次直流停运事故。通过对3个换流站主循环泵控制回路进行比较和分析,查找出宜都换流站内水冷主循环泵变频器的隐患,并对取消变频器的可行性进行了分析。
Yidu converter water cooled main circulating pump through the inverter control,while Longquan and Jiangling converter station through the soft start control unit.Because the inverter fault,Yidu converter station has appeared several times DC outage.through to the three station main circulating pump control circuit for comparison and analysis,find out the Yidu converter water cooled main circulating pump inverter problems,and the feasibility of canceling inverter is analyzed.
