Abstract This paper presents a modelling method for elctric energy production of hydroelectric plants and hydro-mechanical-electric coupling of large-scale reservoir. According to the law of conservation of energy, a hydro-mechanical-electric coupling model was constructed to formulate the electric energy converted from kinectic energy, potential energy, pressure energy and the reservoir energy. Reservoir energy is analyzed by such way, in which water body of reservoir is divided into multiple levels due to the shape of the bottom of the reservoir. By using the priciple of force analysis and energy conversion. The dynamic characteristics of instant power rate of hydropower-diven generator is studied for different factors, such as penstock angle, reservoir adjustment ability, reservoir water body, and maximal usage hours and so on. Some examples are employed to illustrate the feasiblility of the proposed method, and the simulation results shows that it could provide theory basis for the hydropower plant construction, economic operation and high effective utilization and transformation of hydro-energy.

Key words： Hydropower plant divided water bodies of reservoir reservoir energy hydro-mechanical-electric coupling model
