An optimal dispatching method for joint flood control of mixed cascade reservoirs considering the use of flood diversion and storage embankments

Abstract

The invention discloses a combined cascaded reservoir combined flood control optimal dispatching method considering the use of flood diversion and storage embankments, comprising the following steps: S1, obtaining samples of flood diversion flow, flood diversion time, and submerged area / flood diversion volume when the embankment may be used for flood diversion; S2, training the artificial neural network model based on the sample, constructing the flood diversion flow-submerged area / flood diversion volume spatio-temporal prediction knowledge base; S3, establishing a flood control optimization dispatching model considering the use of flood diversion and storage embankments; S4, based on the spatio-temporal prediction The knowledge base calculates and analyzes the optimal dispatching model for combined flood control of mixed reservoirs considering the use of flood diversion and storage mixed reservoirs combined with civil embankments, and obtains the optimal dispatching scheme. The present invention constructs flood diversion flow-submerged area / flood diversion amount spatio-temporal prediction knowledge base by training artificial neural network, and uses it as a boundary condition of combined cascade reservoir joint flood control optimal scheduling model, so that flood diversion information can be extracted in real time and real-time scheduling can be realized .

Description

technical field [0001] The invention belongs to the fields of reservoir flood control dispatching and flood storage and detention area flood dispatching in hydrology, and more specifically relates to a combined flood control optimization dispatching method of mixed cascade reservoirs considering the use of flood diversion and storage embankments. Background technique [0002] Flood disaster is one of the serious natural disasters. Flood control optimization scheduling is a very important task. Good flood control optimization scheduling can keep the watershed reservoirs and flood storage embankment in the best use state, thereby maximizing the flood control benefits of the watershed. Fully guarantee the flood control safety of the reservoir itself, minimize the flood diversion loss of flood storage and embankment, and ensure the joint flood control safety of the river basin. Therefore, it is of great significance to study the optimal dispatch method of flood control. [0003]...
