Modelica for large scale aircraft electrical network V&V

More electrically powered aircraft reveals some sig- nificant advantages such as weight decrease, reduced maintenance requirements and increased reliability and passenger comfort. However, the development of the future more-electric aircraft (MEA) systems is a very challenging task. Its complexity may be han- dled by a model supported design approach for the to- tal aircraft design process. A key factor of applying model based design is dedicated modeling and sim- ulation techniques for all design phases. The high- est complexity can be seen in the systems validation and verification phase where the aircraft system is in- tegrated from the supplier’s models. While the capability to conveniently model complex physical systems with Modelica is generally accepted, the capability to perform large scale model integra- tion and analysis as part of a validation and verifica- tion process remained unproven. In this paper we give evidence of Modelica/Dymola to be suitable for the virtual testing of complex energy systems in the future MEA design process. We demonstrate the modeling and the simulation results of component stand-alone tests as well as the tests of an integrated aircraft power network
