公伯峡水电站调速器的交叉冗余实现方案

Crossing Redundancy of the Digital Governor of Gongboxia Hydropower Station

介绍了公伯峡水电站(5×300 MW)微机调速器的交叉冗余实现方案、双机切换原则和切换 方法，同时指出了双可编程逻辑控制器(PLC)微机调速器在国内大型、巨型水轮发电机组上运行的 可行性。

The crossing redundancy scheme of the digital governor and dual PLC switch principle and switch method of the Gongboxia Hydropower Station （5×300 MW） are introduced. The feasibility of dual PLC digital governor running on the domestic large or huge water-turbine generator set is pointed out.
