摘　　要：介绍了二滩水电站调速器的总体结构,微机调节器的工作原理和应用效果。微机调节器由两套相互独立相互通讯的Quantum系列PLC控制,具有独立的供电电源系统、独立的信号采样(机组频率、导叶开度、有功功率等)通道和独立的输入输出通道。调速器实现双微机调节器及其输入输出通道的交叉冗余,并进行适应式变参数的转速调节和功率调节。着重描述了交叉冗余双微机调节器的容错控制和功率控制方法。This paper introduces the general structure,the operation principle and the use result of the dual microcomputer governor for Ertan Hydropower Station.The microcomputer regulator is controlled by two sets of independent Quantum series PLC.They can communicate each other and each has respective power supply,independent signal sampling paths and independent I/O channels.The I/O channels are of cross- ing redundancy,the controllers are of frequency adjustment and the power control is with adaptive variable parameter rule.The paper emphatically describes the methods of the fault-tolerant control and the power adjustment.

关 键 词：交叉冗余 PLC 适应式变参数 功率控制 容错控制
