| The more-electric aircraft concept is part of everyday's life in the aeronautical industry. The design of more efficient aircraft forces manufacturers to eliminate the combination of hydraulic, pneumatic, mechanical and electrical power and to use mostly electrical systems.;Aircraft design and safety aspects have to be taken into account with increasing electrical load and electrical performance demand. New tools have to be developed to help designers to study new aircraft architectures and to validate performance with an increasing number of details and complexity in electrical systems.;Aircraft electrical system simulation tools and models must be developed to study network stability problems, electromagnetic transients, short-circuit currents and harmonic content. It is also imperative to study control systems and automatic operations to validate safety and performance issues. Numerical methods are important and efficient for studying aircraft power systems to create more efficient electrical system designs and to conduct research on new architectures.;This report presents an initial attempt for modeling the electrical power system of Bombardier's Global Express aircraft in the simulation environment of EMTP-RV. EMTP-RV is capable of simulating electrical systems for steady-state conditions and both, fast and slow transients. Main power system component models are developed with the available data and then connected together to show the capability to perform global simulations. A study case presents the model performance using a predetermined scenario. It is shown that such a model can be used to search for abnormal performance conditions. Needs and improvements are listed and left for future research projects.;This report delivers a complete first benchmark that can serve as basis for future work in the modeling and simulation of electrical systems. It innovates by delivering an increased level of details and simulating the complete electrical system for the Global Express aircraft. Further expansion can be easily achieved if physical component details become available. |
