This project proposes a more efficient and robust power supply for emergency situations in a more electric aircraft (MEA). At first, a hybrid power supply consisting of an air driven genertor (ADG) connected in parallel with a battery pack is considered for the study. Later on, the ADG is replaced by the fuel cells-ultra capacitor system. The main goals of this project are to develop a model of the hybrid power supply and to validate this model using simulation and experimental results.The methodology to achieve the desired goals is the following: The first step will be to model essential loads connected to the ADG. Bombardier will provide information regarding essential loads, flight phases and load sequencing, nominal and peak power requirement associated with the CRJ 900. Based on that information, simplified and generic load models will be developed in SimPowerSystems (SPS). The next section of the project will cover the design, modeling and simulation of the ADG-battery hybrid system. Generic battery and ADG models developed by ÉTS (École de technologie supérieure) will be used for the simulation. The next part of this project will be to design, model, simulate and test the hybrid system, which consists of a fuel cell stack in parallel with a battery and/or super capacitors. Generic models of the fuel cell and battery also developed by ÉTS will be a perfect starting point for the purpose. A reduced prototype of the system will be implemented at the ÉTS power electronics laboratory in order to determine accurately the model parameters and to validate the model performance. The final part of the project will focus on the modeling of loads such as the transformer rectifier unit (TRU) and the electro-hydrostatic actuator (EHA) which are present in MEA.This project presents a new application of fuel cells in aeronautics. With recent technological advances on fuel cell components (electrodes, membrane and catalysts) and pressurized hydrogen tanks, fuel cells can be considered as potential source in aircraft electrical systems. This project will be beneficial to aircraft companies not only in term of fuel consumption and maintenance, but also environmentally as fuel cells produce power with low toxic emissions.

该项目建议在更高效，更强大的电力供应中，以防止电动飞机（MEA）中的紧急情况。起初，考虑了由与电池组并行连接的空气驱动发电机（ADG）组成的混合动力供应。后来，ADG被燃料电池 - 耗时电容器系统取代。该项目的主要目标是开发混合动力供应的模型，并使用仿真和实验结果验证该模型。实现所需目标的方法是：第一步将是建模与ADG连接的必需负载。 Bombardier将提供有关与CRJ 900相关的基本负载，飞行阶段和负载测序，标称和峰值功率要求的信息。根据该信息，将在SimpowerSystems（SPS）中开发简化和通用的负载模型。该项目的下一部分将涵盖ADG-Battery混合动力系统的设计，建模和模拟。 Éts开发的通用电池和ADG型号将用于模拟。该项目的下一部分将是设计，型号，模拟和测试混合系统，该系统由与电池和/或超级电容器并联的燃料电池堆栈组成。 éts开发的燃料电池和电池的通用型号将是目的的理想起点。系统的原型还原将在ÉtsPower Electronics实验室实施，以确定模型参数并验证模型性能。该项目的最后一部分将集中于诸如变压器整流器单元（TRU）和MEA中存在的电静态执行器（EHA）等负载的建模。该项目在航空通用药物中提出了新的燃料电池应用。随着燃料电池组件（电极，膜和催化剂）和加压氢气罐的最新技术进步，燃料电池可以被视为飞机电气系统中的潜在来源。该项目不仅在燃料消耗和维护方面都对飞机公司有益，而且由于燃料电池产生低毒性排放的电力，因此也将是有益的。
