太浦河水闸与泵站联合调度运行研究OA

To establish and implement a joint operation mechanism for a near-field coupled system with cross-affiliation relationships,and to address the challenge that the control and operation in the joint dispatching of the Taipu River Sluice and pumping station cannot adapt to dynamic variations in hydrological conditions,this paper took the Taipu River Sluice and the Taipu River Pumping Station in the Taihu Lake basin as research objects.Using the comparative analysis method and techno-economic index evaluation method,and based on the actual operation data of the two projects from 2019 to 2025 as well as real-time basin hydrological conditions,the study focused on analyzing and investigating the boundary conditions for temporary pump shutdown with sluice opening and temporary sluice closure with pump startup during joint operation and dispatching.The results show that when the Taipu River Pumping Station operates in the water supply mode,the pump should be shut down and the sluice opened promptly if the water level difference between the upstream and downstream of the Taipu River Sluice is≥2 cm,the water level difference between the downstream of the Taipu River Sluice and Pingwang Hydrological Station is>0 cm,and such real-time monitoring data persist for no less than 30 min.When the Taipu River Sluice operates in the water supply mode,the sluice should be closed and the pump started promptly if the real-time flow rate is 0 m3/s,and the above real-time monitoring data last for at least 30 min.Verified by the techno-economic index evaluation method,the proposed boundary conditions can effectively improve pumping station efficiency,reduce unit energy consumption and water supply cost,and achieve comprehensive technical and economic optimality of the projects.The research findings can provide practical references for the implementation of regulation orders and control operation of hydraulic projects in the Taihu Lake basin,offer technical support for improving the regulation accuracy of key hydraulic projects,and lay a solid guarantee for water supply security in the eco-green integrated development demonstration zone in the Yangtze River Delta.
