Study on Pumping Equipment Performance Optimization for Cascade Pumping Station

北京密云调蓄工程是匹配南水北调来水和地区用水不均衡而设置的大型调蓄工程,从团城湖经九级泵站加压调水至密云水库。工程沿线水工建筑物众多,实际调水过程复杂。面临不同要求的调水任务,梯级泵站组要在不同的工况下都能高效运转,所以对泵站系统的运行优化分析显得尤为重要。文章通过建立水力学仿真模型,对泵站进行优化分析,提出高效运行方案,研究成果对梯级泵站优化提供一定的指导作用和技术支撑。

Beijing Miyun Reservoir is a large-scale reservoir used to match the disproportion between the southern water transferred from the north and regional water use,starting from the Tuancheng Lake,passing by the pumping station in grade nine,to fill the pressure,then to transfer water to the Miyun Reservoir. There are many hydraulic structures along the project,and the process of water conveyance is complex on the project site. Being faced with the water transferring tasks with different demands,requiring the cascade pumping station group to operate efficiently under different project situations,therefore,it is important especially to conduct the optimal analysis for operation of the pumping station system. Through establishing the hydraulics simulation model,this study analyzed the pumping station optimization,putting forward the high-efficiency operation scheme,and the researched results will supply guiding and technical supporting for the optimization of cascade pumping stations.
