摘要
介绍了水布垭电站三微机调速器的总体结构、冗余策略、切换原理和应用效果。调速器由3套相互独立相互通讯的Quantum系列PLC控制,实现了3微机调节器及其输入输出通道的交叉冗余,具有良好的容错控制性能。
A triple micro-computer governor with crossing redundancy is adopted in Shuibuya Hydropower Station.The general structure, redundancy strategy, switch principle and application effects of this governor are introduced.The gov-ernor is controlled by three sets of independent Quantum series PLC which can communicate with each other.Thus, the micro-computer regulators and their I/O channels are of crossing redundancy, which provides a good fault-tolerant con-trol performance.
