Sponge city flood optimal scheduling method suitable for complex hydraulic connection

Abstract

The invention discloses a sponge city flood optimal scheduling method suitable for complex hydraulic connection. The method comprises the steps of building an urban hydraulic connection topological relation graph; determining main nodes of flood scheduling, and optimizing and calculating a time interval; determining a target function of flood scheduling according to the main control target of flood scheduling; determining a constraint condition of flood scheduling; establishing a flood scheduling model according to the target function and the constraint condition of flood scheduling; accordingto the priority of the target function of flood scheduling, a hierarchical optimization method is adopted, the optimal calculation time interval of flood scheduling is combined, a flood scheduling model is optimized and solved, a flood scheduling system is integrated, and urban flood scheduling is guided according to the optimal scheduling result of the flood scheduling model. Aiming at the sponge city flood scheduling problem with complex mesh hydraulic connection, blindness of an existing experience scheduling mode can be avoided, scientific and refined scheduling of the city flood problemis achieved, and city flood disaster loss is eliminated or reduced to the maximum extent.

Description

technical field [0001] The invention relates to the technical field of urban flood control and disaster reduction, and more specifically relates to a sponge city flood optimization dispatching method applicable to complex network hydraulic connections. Background technique [0002] Urban flood control and disaster reduction is one of the main purposes of sponge city construction. Sponge city construction aims to maintain or restore the city's "sponge" function through various technologies such as infiltration, stagnation, storage, purification, use, and drainage, and realize a benign urban hydrological cycle. . From the perspective of non-engineering measures, in order to systematically and efficiently exert the functions of the project on flood reduction, transfer, regulation and storage, and achieve the purpose of effectively eliminating or mitigating urban rain and flood disasters, carry out urban flood optimization dispatching work, and form a scientific dispatching Dec...

Problems solved by technology

The empirical scheduling method and the traditional water resource scheduling method cannot consider complex network hydraulic connections. There are many time-space combinations of lake storage and discharge, control gate operation, and pump discharge flow decision-making. The coupling relationship of each constraint is complicated. The empirical scheduling method cannot be global, The unified scheduling of all time and space cannot give full play to the best effect of the sponge city project, so it cannot be applied to the complex flood scheduling problem of the sponge city
