[Abstract]:Our country is rich in hydropower resources, hydropower plays a very important role in the pattern of energy resources. With the increasing shortage of energy in the world today, the development of hydropower construction has become the inevitable choice of our country's energy strategy adjustment. Making full use of hydropower resources can improve the ecological environment and social and economic benefits. After years of development, small hydropower has become an important foundation for the development of rural economy and society in China. It can improve the utilization efficiency of hydropower resources and increase the power generation of cascade hydropower stations. Firstly, this paper summarizes the present situation and future trend of hydropower development in China, and analyzes the problems existing in the research of hydropower stations' optimal dispatching. In this paper, the basic theory and mathematical model of cascade hydropower station with leading reservoir are summarized. On the basis of this, the secondary water distribution model of cascade hydropower station is put forward, and the concrete steps of solving the model by dynamic programming are introduced in detail. At the same time, the system development of secondary water distribution of cascade hydropower stations under the monitoring platform is discussed, and an example is selected for analysis and verification. The main content of this paper is: the research object of this paper is the small cascade hydropower station of the leading reservoir. On the basis of expounding its basic theory and characteristics, this paper systematically summarizes the long and short term optimal operation of the faucet reservoir. The mathematical model of combined optimal operation and economic operation of cascade hydropower stations of the leading reservoir. (2) on the premise of generating water consumption of cascade small hydropower stations within a given dispatching period, The conventional water use plan is to distribute the water consumption of power generation in the average dispatching period or to distribute the water for power generation according to the experience, which often results in the unreasonable distribution of water quantity during the dispatching period. On the basis of the economic operation in the plant, this paper puts forward the redistribution of generation water consumption during the dispatching period of cascade small hydropower, and establishes the secondary water distribution model of cascade small hydropower. The concrete steps of solving the model by dynamic programming are described in detail. Through the secondary distribution of water quantity, the error between the actual inflow flow of reservoir and the theoretical inflow flow of runoff prediction in each period of operation period can be eliminated. It improves the power generation efficiency of cascade small hydropower optimal dispatching, and better guides the practical operation of cascade small hydropower. According to the basic principle of system development and technical support, the module design of cascade small hydropower optimal dispatching system is carried out. This paper explores the development and implementation of secondary water allocation system of cascade small hydropower based on monitoring platform. The system can automatically realize the secondary water allocation and optimal dispatching of cascade small hydropower. The automatic management level of cascade hydropower stations is improved. (4) taking Luoning cascade small hydropower stations as the research object, the secondary water distribution model of cascade hydropower stations is established, and the dynamic programming method is used to solve the problems. Under the premise of generating water consumption in a given dispatching period, the model redistributes the generation water consumption in each period of the dispatching period, and corrects the error between the actual reservoir flow and the runoff forecasting theory in each period. The practical operation of cascade small hydropower is guided.
