Study and Assessment by Simulation of Aircraft Full DC Electrical Power System and Energy Management: Special Session on EMR and Other Graphic Description

In aeronautics, the optimization of the global energetic efficiency, the reduction of the embedded weight and the need to meet the growing energetic requirements lead to develop new and original solutions to generate the electrical energy, to distribute it, to convert it and to store it aboard the aircraft. In this context, the CETIP project consists in studying and in assessing new electrical architectures and new technologies of components for more electrical aircrafts. To complete this study successfully, a modeling of the electrical power system is necessary with a view to assess its operation by simulation. This study is carried out with the Energetic Macroscopic Representation. In a first part, the architecture and the modeling of the electrical power system are defined. Then, a control structure is suggested with a strategy for energy management, which is adapted to the application constraints. Finally, the power system operation is assessed on a mission. The simulation results are presented and commented in this paper.
