Research & Design Of Generalized Multireservoir Optimal Operation System

The current reservoir operation systems are usually designed for particular river basins. When developing for other rivers, we must design the system again and again. There are lots of common elements in reservoir operation systems developed for different watershed, such as basin physical elements, model designing and algorithm designing. In order to improving effectiveness and efficiency of reservoir operation systems, this paper abstracts the commonness things from different reservoir operation systems, and build a hydropower modeling tool and some general purpose models. Using this computer aided modeling tool, we can implement this system for particular rivers quickly.Based on the theoretical research on software reuse and domain engineering, this paper first analysis the commonness and variability of reservoir operation decision support system,then point out the main tasks of general purpose system. These are the foundations of the solution for the new system in the following parts of this paper. This paper analysis the new kind system from five aspects, such as watershed multireservoir modeling tool, general purpose math models, general purpose algorithm, topology description for dynamic systems and system framework, then it discusses the relations among the five aspects and gives a suit of solutions for the new system.Graphic multireservoir modeling tools are built in the new system, and it applies a topology algorithm module to cope with calculation order. Cooperating with the module of topology algorithm, the new system applies generalized dynamic programming algorithm for single reservoir optimal operation and generalized dpsa algorithm for multireservoir.At the end, an example is provided for the Yangtse River watershed in Sichuan Province. The implementation of new system has brought marked engineering benefit in the Sichuan province.
