Description
Technical Field
The invention relates to the field of wind tunnel group test operation scheduling, in particular to a wind tunnel group medium-pressure scheduling method.
Background
Large wind tunnel equipment and facilities are major strategic resources in China, and wind tunnel tests need multiple power resources such as pure water, electric power, high-pressure air, medium-pressure air, vacuum, nitrogen, hydrogen, oxygen and the like. Particularly, along with the centralized construction and the centralized management of the wind tunnels, the high-frequency and various pneumatic tests developed by the wind tunnel group provide great challenges for timely guarantee and reasonable allocation of power resources.
The requirement of medium-pressure air resources greatly fluctuates along with the development of test tasks and the guarantee period, and the reasonable scheduling of large-scale medium-pressure compressor units has the relation to energy conservation and emission reduction, the completion of wind tunnel test tasks and the stability of power supply. The current scheduling method is that once a wind tunnel has a test power resource demand, a power guarantee department starts a medium-pressure compressor unit to pump air, so that frequent impact on a power grid and excessive guarantee of power resources are easily formed on one hand, and on the other hand, the medium-pressure compressor system has the maximum limitation of the number of start-stop times per day, and the frequent start causes the performance degradation and equipment loss of the medium-pressure compressor unit, a dryer and other systems, thereby seriously affecting the economic benefit of an enterprise.
The medium-pressure compressor has large current at the moment of starting, and the compressor is quite energy-consuming and easy to damage due to frequent switching. Therefore, under the condition of meeting the power requirement of the wind tunnel test, in the face of uncertainty of medium-pressure resource requirement, how to formulate a reasonable operation scheduling strategy of the medium-pressure compressor unit is the primary consideration of medium-pressure aerodynamic scheduling of the wind tunnel test, frequent starting of the medium-pressure compressor unit is avoided while the wind tunnel test is guaranteed, and supply pressure conflict and the like are avoided.
An integrated test scheduling system ISS appears in 2019, the system reduces the influence on the aspects of work delay and the like caused by insufficient test resources and test schedule conflict, and ensures that various equipment facilities and related personnel can meet the requirement of a high-priority test task to the greatest extent. The ISS system takes project management software P6 as a core, realizes the compilation and real-time update of a test plan, and the balance and distribution of resources and cost, and focuses on short-term (week unit), medium-term and long-term test task planning and personnel allocation.
However, the technology is mainly used for medium and long-term test planning and wind tunnel staggered starting, and a method for intelligently scheduling the medium-pressure compressor unit according to different test task requirements is not developed for wind power groups.
