Abstract:
Improving the regulation and storage capacity of pipe networks is an important research topic in relieving urban waterlogging disasters. Studies have been conducted to design scheduling strategies with the single objective of reducing system overflow, lacking consideration of the loss and risk caused by frequent gate openings and closings.To address this issue, this paper proposes an optimal rolling control model for an urban sluice pump group drainage system with the optimization goal of reducing system overflow and gate opening and closing times, using the neighbourhood of The Hague in Norfolk as an exemplary study. The overflow volume of the optimal rolling control model is 31.2%lower than the value of static scheduling.The gate opening and closing times of this model are 59.8% lower than the dispatching scheme with the single goal of reducing the overflow, while the overflow of the drainage system has been reduced.The proposed method is helpful for the formulation of a dispatching scheme of urban drainage system in case of waterlogging.
