Embodiment Construction

[0046] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0047] Please refer to figure 2 , the present invention provides an urban reservoir flood control compensation optimization scheduling method, comprising the following steps:

[0048]Step S1: Set the flood control section as M, and divide the flood catchment range N corresponding to the interval between the reservoir dam site and the section M according to the regional topography and topological structure of the pipe network;

[0049] Step S2: Calculate the area of ​​different land use types in the corresponding interval catchment area N between the reservoir dam site and the section, and calculate the net rain process according to formula (1):

[0050]

[0051] In the formula, p(t) is the net rainfall in the period t, P(t) is the rainfall in the period t obtained from the weather forecast, Ψ i is the runoff coefficient of the i-th land use type i...

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 ...
