Embodiment 1

[0062] A dynamic topology modeling method for high-pressure air resources in wind tunnel clusters, such as image 3 shown, including:

[0063] S10. Obtain the on-site operating status of the power system

[0064] The power system includes the test dynamics of each wind tunnel in the wind tunnel group, the tank group dynamics, the compressor group dynamics and the valve status;

[0065] S20. Obtain the adjacency matrix A of the high-pressure air distribution network n×n

[0066] Taking the gas distribution network of high-pressure air resources as a directed graph, the compressor unit, pipeline airflow confluence point, tank group and wind tunnel in the gas distribution network as nodes, and the valves in the gas distribution network as edges, the adjacency matrix is ​​obtained:

Abstract

The invention is suitable for the field of wind tunnel group test operation scheduling, and particularly relates to a wind tunnel group high-pressure air resource dynamic topological structure modeling method and system and air consumption calculation. And constructing a dynamic topological structure of the high-pressure air resource distribution network of the wind tunnel group based on the graphic database and the adjacent matrix, and calculating the high-pressure air resource consumption of a specific wind tunnel based on the structure.

Description

technical field [0001] The invention relates to the field of wind tunnel group test operation scheduling, in particular to a dynamic topology structure modeling method, system and air consumption calculation of high-pressure air resources of a wind tunnel group. Background technique [0002] Large-scale wind tunnel equipment and facilities are major national strategic resources. The wind tunnel group usually includes a dozen or even dozens of production wind tunnels. Each wind tunnel test requires pure water, electricity, high-pressure air, medium-pressure air, vacuum, nitrogen, Hydrogen, oxygen and other power resources. In order to meet the test requirements of the wind tunnel group, the configuration of the power system is often very complicated. [0003] Taking the high-pressure air system as an example, the high-pressure air system is divided into 32MPa and 22MPa high-pressure air systems. The main equipment includes a reciprocating compressor, a dryer, a 32MPa high-pr...
