Research On Shiquan Reservoir Optimal Dispatching After Unit Enlargement

The operation chart of individual and associated operation of new and old units are plotted by using series of multiyears flows. At the same time, based on flood dispatching auto-monitoring system of ShiQuan reservoir, which is a hydrological data telemetering system and real-time flood forecasting system, this paper studies and develops the flood-dispatching system and perfects the flood-dispatching auto-monitoring system. The main results of this paper are as follows:(1) The operation chart for individual and associated operation of new and old units, is plotted by using series of multiyears flows and the associated charts is advised to direct the reservoir operation.(2)On the basis of analysis on the characteristics of hydro-information observation system and flood forecasting system, some key problems in flood operation such as dispatching period of time, decision-making method and so on are studied.(3) The study and development of flood-dispatching simulation model. The theory and practice of the flood dispatching on reservoirs are analyzed. In terms of the characteristics of the practical flood dispatching, the simulation model of flood dispatching are advanced for the first time, and its theory and resolvent are studied, at the same time the software for the model is developed.(4) Study on flood dispatching rules model and the optimal dispatching model. The flood operation rules are worked out in terms of programming and with the aim of guiding the operation of the reservoir. According to the flood dispatching rules of ShiQuan reservoir, coordinated with the open-close program of the gates, the flood operation rules model is designed and developed, thus guiding the operation of the reservoir.(5) The study and development of real-time flood dispatching. On the basis of analyzing the advantages and disadvantages of optimal operation modelsi some appropriate models are chosen to compose real-time flooddispatching model base, and real-time system is developed by means of advanced computer software, which has the function of establishing operation scheme at certain time step.(6) The study and development of flood dispatching decision support system (DSS). The simulation model, designing rules model and optimal dispatching model are integrated in order to be selected by decision maker. At the same time, many sorts of auxiliary function are provided, such as print preview, inquirement, report form and so on.
