Joint optimization scheduling method for cascade navigation hub based on waterway hydrodynamic calculation

Abstract

The invention discloses a step navigation hub joint optimization scheduling method based on channel magneto-rheological fluid, which comprises the following steps: dividing the section of the whole channel, and setting a virtual section at each hub; respectively adopting a water balance calculation method solving a Saint-Venant equation and considering the hub scheduling for the natural section of the channel and the virtual section of the hub to determine the water level and flow value at the time period tail of the whole channel; and in a process of optimizing the model, automatically eliminating the unsatisfactory scheduling scheme. The method disclosed by the invention can realize synchronous calculation of the hydraulic elements of the section of the whole channel to meet the requirements of the step navigation hub joint scheduling for high calculation precision of the water level of the channel and the flow velocity at the entrance area; the channel is canalized through a process of optimizing the step hub scheduling, the water flow conditions at the entrance area and the approach channel are improved; and meanwhile, the power generation strategy is optimized to maximize the comprehensive utilization benefits of step navigation and power generation.

Description

technical field [0001] The invention relates to the field of shipping scheduling, in particular to a method for joint optimization scheduling of cascaded navigation hubs. Background technique [0002] With the successive completion and operation of a large number of cascade navigation and power hubs such as the Three Gorges Cascade, the Upper Yellow River Cascade, and the Jinsha River Cascade in China, formulating a joint dispatching plan for the cascade hubs and carrying out dispatching according to the plan has become an The key to comprehensive utilization of benefits. [0003] At present, the goals of joint dispatching of hub groups that are concerned at home and abroad are mainly power generation efficiency and flood control safety. With the increasing concept of sustainable development of water resources, the multi-objective scheduling problem of comprehensive consideration of water resources, ecology and environment has become a hot spot in domestic and foreign resea...

AI Technical Summary

Problems solved by technology

However, the construction of the cascade navigation hub blocks the continuity of water flow conditions in the channel and destroys the natural hydraulic characteristics of the section, so it is impossible to directly solve the hydraulic model of the entire channel section.
