A Method for Determining the Feasible Solution of Steam System Optimal Scheduling in Iron and Steel Enterprises

Abstract

The invention is applicable to the field of energy scheduling technologies in iron and steel enterprises, and provides a method for determining a steam system optimization scheduling feasible solution of iron and steel enterprises. The method takes initialization of a free variable of schedulable equipment on a topological structure of a steam medium network as the main line, takes all constraint conditions such as physical constraints of steam media and process constraints of multi-unit equipment into account comprehensively, gradually advances according to a steam production and consumption processes, and obtains the feasible solution which naturally meets all of the constraint conditions under the premise that the complex iterative search computation is not required through carrying out processing procedures such as random allocation, constraint inspection, relevance detection and adjustment correction on all variables in the steam system; and if low-quality steam cannot meet steam requirements for production, inlet steam flow rates of some temperature reducing and pressure reducing devices are initialized in priority during the variable allocation process of high-quality steam associated with the low-quality steam in a predictable manner, the possibility that the generated steam system optimization scheduling scheme is an infeasible solution is reduced, and the software and hardware resource consumption of repeated iterative computations is reduced.

Description

technical field [0001] The invention belongs to the technical field of energy dispatching in iron and steel enterprises, and in particular relates to a method for determining a feasible solution for optimal dispatching of a steam system in an iron and steel enterprise. Background technique [0002] The iron and steel industry is the basic pillar industry of the national economy, and it is also a resource- and energy-intensive industry. Energy consumption is an important factor that determines the production cost and profit of the iron and steel industry, and it is also the main reason that affects the environmental load. On the one hand, iron and steel enterprises have a long production process with various procedures and equipment, and each process is connected with each other, and each process and equipment is associated with multiple energy media; on the other hand, iron and steel enterprises need to use more than 20 types of energy. These energy media not only have vari...
