Abstract: Reflecting on overseas governors in the Three Gorges Project left-bank power station, it is suggested that domestic governor can be used in the Three Gorges right-bank power station. In order to improve the reliability and to realize digitalization of the governor, some research topics on optimizing the design and selecting important parts of the Three Gorges power station governor are proposed, such as the selection and proof of the governing system structure, the design and research of the software modularization, etc.. On the basis of these researches, concrete technical proposals for the governor of Three Gorges Project are as follows: adopting full-digital AC servo-motor and driver as a transforming part between the digital signs and mechanical displacement, employing a structure of micro-computer adjustor and digital electrical-hydraulic sequent moving system, and a large-size programmable controller on PC platform.
