The Research On Technology And Selection For Hydroturbine Governor

Hydroturbine governor is one of the important controlling devices in the hydro power plant, and its performance exerts important influence on the quality of electric energy and the operational reliablity of the hydro power plant.lt is an active subject to research some technology and selection for hydroturbine governor.In the first of the paper, the principals and characteristics of the hydroturbine governor are discussed and then an overview about the history, current status and trends of hydroturbine governor are introduced. Then analyzes and discuss some technology of hydroturbine governor, including with the regulating modes, regulating laws, control strategy and the disposition of hydroturbine governor. And mainly introduced the neural-network theory. The neural-network basded intelligent control for hydroturbine governor is studied. The judgement system of hydroturbine governor is given based on the specification, and mainly judge the technics of some hydroturbine governor that made in China. Evaluates the benefit of the new hydroturbine governor. The principle of selection is established for hydroturbine govemor.The selection and design for hydroturbine governor of the Three Gorges Project Units are presented. At last, the authour gives a summary of the whlole thesis and some suggestion about hydroturbine governor.
