The micro-computer regulator is controlled by two sets of independent Quantum series PLC which communicates with each other. The micro-computer regulator runs with independent power supply system, independent signal sampling path (such as frequency measurement, wicket gate position sensor, active power sensor, etc.) and independent IO channels. The micro-computer regulator carries on the dual crossing redundant of controllers and the IO channels. At the same time, it carries on the frequency adjustment and power control with the adaptive variable parameters rule. The paper describes emphatically the methods of fault-tolerantly control and power adjustment.概述二滩水电站位于雅砻江下游四川省攀枝花市境内，装有 6 台单机容量 550MW 的水轮发电机组，总装机容量 3300MW，多年平均发电量 170 亿度，是我国 20 世纪末建成投产的最...
