Power Generation Loss Analysis And Caculation About Longyang Xia Hydroelectric Power Station In The Yellow River

The Longyang Xia hydroelectric power station is the first large-scale and carryover storage reservoir in the Yellow River, and holds the post of the main modulation power plant in northwest electrical network. Recently under the water used supply and demand contradictory prominent influence, the emergent water dispatch has become an important. And add to oneself exist the dispatch question, Longyang Xia power generation loss to be serious, at the same time the yellow river water resource management and northwest electrical network safe operation has had the serious influence.The implementation that paid for the water resources used is the inevitable trend, profits the basic principle according to who which who pays expenses, the upriver benefit sacrifice supports to the downriver economical development, obviously has disobeys the just principle, according to loses the mechanism establishment which carries on compensates is the water resource management inevitable trend.This article from analyzed the runoff datum to go into the Longyang Xia reservoir, studies the situation about runoff abundant and dry change, and based on the water situation proposed using NN (Neural Networks) to forecast, and implemented the reservoir optimization operation on forecast basis. Through adopted the different dispatch way the computation contrast discovery, relatively the implementation to optimize the dispatcher to be allowed to enhance the power rate.Simultaneously the power generation loss computation model has been established, separately on normally situation and unusually inflow situation the power generation loss to becomputed. Normally inflow situation the power generation loss is refers to the less between the different dispatch way .The unusual situation includes the water reduction and the emergent water dispatch two kind of situations, and the form of power generation loses was elaborated, as well as the power generation loses was computed under comes the water different combination and using different dispatch method.Through the power generation loss analysis and computation of Longyang Xia, the method that reduced the electric power generation lost was proposed: The reasonable dispatch, the establishment emergent water dispatch compensation mechanism and so on.
