光纤通道代替水电站与升压站间长距离信号传输电缆的实践

Practice of Fiber Channel Replacing Long-distance Signal Transmission Cable Between Hydropower Stations and Their Booster Stations

随着以三峡电站为代表的特大型水电站的陆续开工建设,电站与升压站的联系越来越重要,提供两者之间可靠、有效的跳闸信号传输通道,是保证电站安全运行的重要条件。文中对用长距离传输跳闸信号电缆容易引入干扰源的原因进行了分析,结合葛洲坝水电站工程改造的实践,提出用光纤通道代替长距离电缆传输跳闸信号。

Along with the construction of the Three Gorges Hydropower Plant as the representative of the super-sized hydropower stations, the relationship between hydropower stations and their booster stations become more and more important. Providing reliable, effective tripping signal transmission channel is an important condition to guarantee the safe operation of hydropower stations. The paper analyzes the reason that interference source is easy introduced by long-distance signal transmission cable, and combining with the engineering practice of the Gezhouba Hydropower Plant, the project of using fiber channel replacing long-distance signal transmission cable is proposed and realized.
