Description
Technical Field
The invention relates to the field of model analysis, in particular to an ecological scheduling simulation analysis method of a river channel model.
Background
With the development of the hydropower construction industry in China, a plurality of gate dams are built on the domestic main rivers. The hydraulic association of the gate dams is tight, so that a step joint scheduling research needs to be developed, the scheduling mode of each power station on the river is optimized, and the power generation, shipping and ecological benefits of each step are brought into play to the maximum extent.
Simulation analysis is one of the important means of the cascade joint scheduling research. Through simulation analysis, simulation analysis can be carried out on various cascade scheduling schemes, the implementation effect of the schemes is evaluated, and the method has important significance on comparison and selection and optimization of the cascade scheduling schemes.
However, the step joint scheduling research has a difficulty that the scheduling procedure of each step is changed along with time in the joint ecological scheduling process. Generally, when the ecological dispatching is started, each step starts to increase the drainage flow rate to form an artificial flood peak. Even part of the steps can fully empty the reservoir, and the open state is achieved. And in the later stage of ecological scheduling, each step is gradually closed to store water, and the power generation state is recovered.
At present, the existing river simulation analysis software in the industry, such as SWMM, MIKE, HEC-RAS and the like, cannot perform simulation analysis on the model with the complex scheduling scheme changing along with time. This severely restricts the development of fine analysis and optimization design work of the scheduling scheme. Therefore, it is urgently needed to develop a simulation analysis method, so that designers can simulate hydrodynamic work such as water level, flow velocity and the like in a river channel when each step scheduling scheme changes in the ecological scheduling process, and provide data support for fine analysis and optimization design of the scheduling scheme.

s3, initializing and setting the section bottom elevation of each gate dam in the river channel model and the capacity curve of the pump according to each cascade scheduling regulation;
s4, calculating the flow, water level and flow velocity of each section in the river channel model at the current time step;

When the upstream water level is higher than 62.73m, the water can overflow to the downstream river channel. The boom setting steps are similar to those of a family camp and are not repeated. The main difference is that the elevation of the section bottom is different from the capacity curve (pum curve).

Specifically, considering that the rising dead water level is 34.70m, 420m need to be discharged at least for ensuring navigation3S, therefore, the reservoir area downstream bleed down flow rate 420m is set when the water level is 34.70m3And s. When the normal water storage level is reached, the generator is in a power generation state, and the maximum power generation flow of the generator set is 2800m3And s. When the warehousing flow is more than 2800m3When the water level is changed to be 36.20-37.70 m, the water level interval is set, and the downward discharge flow is 2800m3The number of/s increases to 10000m3/s。
| Water level (m) | Flow rate (m)3/s) |
| 34.70 | 420 |
| 36.20 | 2800 |
| 37.70 | 10000 |
