Urban reservoir flood control compensation optimization scheduling method

Abstract

The invention relates to an urban reservoir flood control compensation optimization scheduling method, which comprises the following steps of S1, dividing a water collection range of a corresponding interval flood between a reservoir dam site and a cross section according to a regional topography and a pipe network topological structure; S2, calculating the rain purification process of the incoming water in the interval; S3, simulating and calculating a flow time sequence of the control section based on a historical rainfall process of an interval incoming water collection region; S4, calculating a flow unit line of the incoming water in the interval; S5, in real-time scheduling, calculating an interval incoming water flow process according to the rainfall forecasting process and the flowunit line; S6, constructing a reservoir flood control dispatching objective function; S7, calculating the initial value of the drainage flow at the reservoir moment; and S8, according to the flood control dispatching objective function of the reservoir and the initial value of the drainage flow, calculating the control drainage flow of the reservoir based on the control constraint condition. The method can be used for accurately and effectively carrying out flood regulation calculation of reservoir flood control compensation scheduling.

Description

technical field [0001] The invention relates to the field of urban waterlogging prevention and control, in particular to an optimal scheduling method for urban reservoir flood control compensation. Background technique [0002] In recent years, urban waterlogging is one of the most serious disasters affecting the normal production and life of cities. In order to effectively prevent and control urban waterlogging disasters, most cities have gradually established a set of effective urban flood prevention and control engineering systems, including fast drainage facilities and storage facilities. Reservoirs, park green spaces, etc. Reservoirs are an important part of urban flood control facilities and an important guarantee for urban water safety. At present, the research on optimal flood control dispatching methods for large reservoirs in river basins has developed relatively maturely, while the research on optimal flood control dispatching methods for small urban reservoirs ...

AI Technical Summary

Problems solved by technology

Due to the small catchment area of ​​the urban area from the urban reservoir to the control section, the high impermeability of the underlying surface, and the fast production and confluence speed, the response time of reservoir dispatching is extremely limited, and the calculation of urban hydraulic models is obviously difficult to meet the response time of real-time dispatching of urban flood control and drainage. needs

In addition, there are certain differences between the principles of flood control and dispatch of urban reservoirs and those of basin-type reservoirs, and the factors to be considered are more complicated
