Abstract

The present application relates to a control method and a control device for an urban drainage system. The urban drainage system control method includes: acquiring a complete simulation model of the urban drainage system, simplifying the simulation model to obtain a simplified simulation model; Rainfall and future forecast rainfall, determine the future flow value of the inflow point according to the historical flow value, current rainfall and future forecast rainfall; use the simplified simulation model to simulate the inflow point and inject the future flow value under different control strategies. The overflow volume of the urban drainage system is determined, the control strategy is determined, and the control method of the water volume facilities is adjusted so that the overflow volume of the urban drainage system is below the target overflow volume. The method of the present application aims to provide a method that can quickly and accurately obtain a control strategy to keep the overflow in the urban drainage system below the standard value, and can quickly find a suitable control strategy and improve the flooding in the urban drainage system. Case.

Description

technical field [0001] The present application relates to the technical field of urban drainage, in particular to a control method and control device for an urban drainage system. Background technique [0002] As the sanitary equipment of modern houses becomes more and more perfect, the number of high-rise buildings increases, the population becomes denser, and the amount of sewage generated by domestic water increases. At the same time, with the development of industry, the amount of industrial wastewater is also increasing. Coupled with rainfall, the city's drainage system has been greatly challenged, so it is necessary to simulate the city's drainage system to find the optimal control strategy for drainage facilities. [0003] In the traditional technology, when calculating the optimal control strategy of drainage facilities, a linear processing method is used, and the model parameters are modified to conform to the linearized relationship, and then the control strategy ...
