Modeling and simulation of large scale power systems in more electric aircraft

More electrically powered aircraft reveals some significant 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. Model based approach provides significant improvement for total aircraft design process. A key factor of applying model based design approach is dedicated modeling and simulation techniques. Among various available modeling languages and tools in this regard, Modelica - an object-oriented, equation based modeling language is gaining more attention and acceptance in the aircraft society thanks to its strong capability to conveniently model complex physical systems. With the simulation results of component stand-alone tests as well as the tests of an integrated aircraft power network, Modelica has been proved to be suitable for the virtual testing of complex energy systems in the future MEA design process.
