Research On Simulation And Optimality For Large-Scale Multi-Stage Water Transfer Project

With the highly-speed development of China's economy, energy source is increasingly playing an important role. As a base of heavy industry, Shanxi has abundant coal resources. However, Shanxi is one of the provinces facing serious water restriction. The situation has been becoming a great obstacle on social development. For the sake of unbalanced water distribution, transfers water is emerging to be a feasible technique of solving water shortage. The Wanjiazhai Yellow River Diversion Project (WYRDP) has stood for that reason.WYRDP is a large-scale and multi-stage delivery water project. The altitude between the water inlet and outlet node is nearly 640m, so-that multi-stage pumping stations need to be used. Nevertheless, multi-stage pumping stations need a lot of energy, so we focus on how to minimize the power consumption. Simulative technology and tool provide a visible modular development environment for delivery water project's designing, running and management. The optimization will give a specified sequence of required flow rates over time.This paper will be based on the background of WYRDP, research on simulation and optimality for large-scale multi-stage water transfer project, using advanced hydraulics simulative calculation analysis software of water ,"MOUSE", with system analysis, establish the hydraulics module of WYRDP. The optimal operation plan of WYRDP pumping stations is solved by means of a treble layer decomposition-coordination model. With the model, different optimal solutions can be found for different layers. The optimal operation algorithm of sub-system is dynamic programming (DP). The calculated result shows that the model and the principle of optimization presented can ensure rational and economical operation of the pumping station with the original facilities. Under the environment of Windows XP OS, according to the model of the DP algorithm, the optimization has been programmed and implemented with MS C#. Simulation model makes observe pump stations running state easily.
