Abstract

The invention discloses a steam system energy expansion transformation optimization method, electronic equipment and a storage medium. The method comprises the steps of obtaining design variables of an existing steam system; based on the design variables, building mass balance formulas and energy balance formulas of all turbines, all stages of steam main pipes and temperature and pressure reducersof an existing steam system and a to-be-transformed steam system; establishing a capability constraint condition; establishing a dosage constraint condition; establishing a target function; and solving the objective function to obtain design variables of the newly added boiler, the newly increased and decreased temperature decompressor, the newly added turbine and the newly added steam header pipe of the steam system to be reconstructed. On the premise of meeting the steam requirements of all production devices of enterprises under different production loads, the capacity of existing equipment is fully utilized to reduce investment of newly-added equipment, and on the premise of ensuring safety and stability of the steam system in the actual operation process, the transformation scheme with the lowest comprehensive cost of the existing steam system is automatically obtained through system optimization, and the economic competitiveness of enterprises can be improved.

Description

technical field [0001] The invention relates to the related technical field of chemical process transformation and optimization methods, in particular to an optimization method for expansion and transformation of a steam system, electronic equipment and a storage medium. Background technique [0002] As one of the main energy sources required by petrochemical enterprises for production, the steam system provides the power for the production equipment to drive the equipment and the heat for heating the materials. On the one hand, with the changes in market demand and the development and production of new processes of enterprises, it is often necessary to expand the production capacity of some of these devices, or to build some new devices under the existing steam system. These factors cause the structure and operating parameters of the steam system to be different from the original design. If it is not possible to judge in advance whether the existing steam system can adapt ...
