A cascade hydropower stations cooperation model based on minimum water consumption was presented. Combined with the forms of reservoir water body energy,and in view of the natural shape and storage characteris?tics of large reservoir,the authors analyze the distributions of water body and the mechanical actions at the inlet of pressure diversion pipe,study the transmission of water flow in pressure pipe and the mathematical expression of turbine generator output,set up a reservoir energy model based on the classification of water body,and on the transformation of kinetic energy,potential energy and pressure energy of water infinitesimal. Emphasis was put on the optimization of water consumption under a certain load. Simulation calculation was conducted for the cascade hy?dropower stations on Hongshui River. The results of calculation demonstrate this model can provide correct and effec?tive guidance for power stations to make full use of water resources,increase the benefits from joint power generation.
