Research on Optimal Dispatching of Water Supply System of Cascade Pumping Station in Zhangfeng Reservoir

In order to analyze optimal dispatching of complex water supply system of cascade pumping station, taking Zhangfeng reservoir as an example, the theory of pump similar is used to implement the theoretical calculation of matching conditions for various commitment unit under variable speed adjustment in cascade pumping stations. Taking the maximal efficiency of water supply system in cascade pumping stations as the goal, the flow balance is matched. Through the analysis and calculation of the flow matching of the cascade pump station in zhangfeng reservoir, it is shown that the flow matching among the stations can be effectively solved by adopting variable speed regulation. For the complex water supply system of Zhangfeng reservoir, flow matching between first and secondary stations is achieved by the method of variable speed regulation. By means of numerical simulation of flow matching, it can provide technical support for optimal operation of cascade pumping stations in Zhangfeng reservoir. The research results provide a reference for optimal operation of other similar pumping stations.
