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2套相互独立、相互通信的Quantum系列可编程逻辑控制器(PLC)控制,每一套PLC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, operation principle and application effect of the dual microcomputer regulator of the governor of Ertan Hydropower Station. The microcomputer regulator is controlled by two sets of independent Quantum series PLC, which communicate with each other. The microcomputer regulator runs with an independent power supply system, independent signal sampling path (such as frequency measurement, wicket gate position sensor, active power sensor, etc. ) and independent I/O channels. The microcomputer regulator carries on the dual crossing redundance of the controllers and the I/O channels. At the same time, it carries on the frequency adjustment and power control with the adaptive variable parameters. The paper describes emphatically the methods of fault-tolerant control and power control.
