Hybrid System Modeling for Middle-Pressure Air Resource Dispatching of Wind Tunnel Group

The demand for medium-pressure aerodynamic resources in large wind tunnel groups fluctuates greatly with the development of test tasks and different guarantee period. However, the instantaneous starting current of medium-pressure pumps is large, so frequent start-up consumes much energy and damages the pumps easily. Therefore, as a typical hybrid system, the reasonable dispatching of medium pressure pump unit is related to energy saving and emission reduction, the completion of wind tunnel test task and the stability of power supply. This paper proposes a hybrid system modeling method based on timed automata, and applied to the wind tunnel group of medium pressure air resource scheduling system. Avoid frequent startup of medium pressure pump unit while ensuring efficient wind tunnel test, aimed at solving the extensively existing in the operation model, large medium pressure pump starting material consumptions of energy consumption is high in the existing technology. It lays a foundation for establishing wind tunnel test scheduling system and realizing multi-resource coordinated scheduling.
