A Multi Level Approach for Aircraft Electrical Systems Design

Abstract

This paper describes the needs, ideas, implementation and application of a multi-level concept used for aircraft electrical systems design. The goal is to easily switch between three model levels in a complex system model, in order to arrive at dedicated models for the needed simulation tasks: a simple and super fast model for energy consumption design, a detailed model for fast network stability analysis and a very detailed model for network quality assessment. Special care was spent on the modeling assumptions and a suitable library concept fitting to the needs. For simplified unitary testing and configuration management of a multi-level models a concept was developed. The approach is demonstrated with an aviation equipment use case. The usage of the models for stability and quality studies is sketched.
