| 摘 要： | 隔河岩水电站大坝廊道排水控制系统存在设备备品、备件不足,技术落后,系统软件工作不稳定等问题,不能按库坝管理要求对排水量进行监控,严重影响廊道排水系统的可靠性。为此,对该系统进行了综合自动化改造,采用TCP6IP通讯,PLC直接上网,异种CPU热备冗余等技术,提高了整个系统的运行可靠性,满足了“无人值班”的要求。

| Abstract: | The drainage control system in the dam of the Geheyan hydroelectric power plant is facing the following problems: inadequate spare parts, out of date technologies, unreliable operation of software, resulting in failure of supervision of drainage discharge as required by the operation of dam and reservoir, which badly hampered the function of the drainage system in tunnels. So such technologies as TCP/IP communication ,PLC net link, different cpu standby, intelligent database(IDB) , were adopted to solve the problems. |
