Design and Simulation Validation of Steam Power Systems Based on MBSE

Abstract

Steam power systems, as one of the critical power systemsin industrial applications, require rigorous design andverification processes. Model-Based Systems Engineering(MBSE) provides a structured approach to decomposing systemarchitecture from top to bottom and enablingmulti-disciplinary collaborative design, ensuring preciserequirement management and efficient design processes. Toaccelerate the iterative design and verification of steampower systems, this paper employs the SysML language toconduct requirement, functional, structural, and parametricanalyses, thereby completing the system architecturedesign. The seamless transformation from system designarchitecture to system simulation architecture is achievedbased on the SysML-to-Modelica tool. Additionally, Modelicasimulation technology is utilized to construct simulationmodels and perform dynamic scenario analyses of the system.Innovatively, this paper proposes a closed-loop technicalapproach for steam power system design, simulation, andverification, which effectively optimizes system design andimproves the efficiency of both design and verificationprocesses.
