Reconstruction method and system of thermodynamic system

Abstract

The invention discloses a reconstruction method and system for a thermodynamic system, and the method and system are based on a function and structure mapping fusion criterion. The reconstruction method of the thermodynamic system comprises the steps that S1, a thermodynamic system scheme meeting user function requirements is obtained through a function structure mapping method, and the thermodynamic system scheme comprises sub-system, equipment and environment interface elements; and S2, according to a thermodynamic system scheme, the subsystems are described according to equipment composition, media, pressure, temperature and materials, and the equipment is described according to structural forms, media, pressure, temperature and materials. And S3, screening alternative subsystem combinations which can be fused and reconstructed according to a medium consistency and structural similarity fusion criterion. And S4, evaluating the feasibility of the fusion reconstruction design for the alternative subsystem combination, and proposing a fusion reconstruction design scheme. According to the reconstruction method of the thermodynamic system, dependence on experience of designers is greatly reduced, better operability is achieved, and the design period can be greatly shortened.

Description

technical field [0001] The invention relates to the technical field of thermal system design, in particular to a thermal system reconfiguration method and system. Background technique [0002] The thermal system converts heat energy generated by boilers, nuclear reactors, solar energy, etc. into mechanical energy and then into electrical energy. In order to ensure the long-term operation of the thermal system, in addition to designing the corresponding equipment to realize the thermal cycle, it is also necessary to design auxiliary support subsystems or equipment to realize the functions of working medium replenishment, working medium and equipment cooling. Taking the steam thermal system as an example, the main equipment is the boiler, steam turbine, condenser and feed water pump. In order to make the condenser operate in the design range, it is necessary to design the cooling water system for heat exchange, and design the air extraction system to maintain the pressure of t...
