隆安县金鸡滩电厂一次主接线改造设计

Main electrical connection upgrade design of Jinjitan HPP

广西隆安县金鸡滩水电厂为了避免因系统故障或本电厂110kV母线及其所连接的设备检修或故障时,而引起3台机组全部停电,导致电厂的电能无法送出,拟将110kV单母线改为单母线断路器分段运行方式,改造后电厂的运行方式将更加可靠、灵活,更能充分发挥电厂的经济效益。

Jinjitan Hydropower Plant is located in Longan county of Guangxi. In order to prevent the electricity output of all 3 sets of units unable to be transmitted outward due to fault of system or maintenance or failure of the 110kV busbar and the equipment connected with it, the original single 110kV bus is upgraded into bus sectionalized with circuit breaker, rendering more reliable and flexible operation and more economic benefits.
