Abstract

Abstract: Since difficulty and complexity of spaceflight missions are increasing, current electric systems in the spacecraft become growingly complicated challenging the spacecraft electrical power system (EPS) architecture development. By using traditional approaches, system architectures are managed by document collections including various reports, documents and data chats. Due to lack of a unified visualization of system architectures, consistency and traceability among data, documents and information are difficult to manage, particular in supporting architecture design and system verification and validation. This paper presents a model‐based systems engineering (MBSE) tool with emphasis on domain specific modeling (DSM), architecture visualization, model transformation and automated verification and validation by using Modelica. The MBSE tool aims to develop the architecture models of EPS, to support MBSE‐driven visualizations of architectural hierarchies inspired by related techniques of Google Earth and to realize architecture‐driven verification & validation by using Modelica language. Finally, through a case study of EPS, we evaluate the feasibility of our tool.
