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.

该项目提出了一种更高效、更强大的电源，用于电动飞机 (MEA) 的紧急情况。首先，研究考虑使用由与电池组并联的空气驱动发电机 (ADG) 组成的混合电源。后来，ADG被燃料电池-超级电容器系统取代。该项目的主要目标是开发混合电源模型，并使用仿真和实验结果验证该模型。实现预期目标的方法。如下： 第一步将对连接到 ADG 的基本负载进行建模，庞巴迪将提供与 CRJ 900 相关的基本负载、飞行阶段和负载排序、标称和峰值功率要求的信息。 SimPowerSystems (SPS) 的下一部分将涵盖 ADG 电池混合系统和 ÉTS（École de technologie superrieure）开发的 ADG 模型的设计、建模和仿真。该项目的下一部分将是设计、建模、模拟和测试混合动力系统，该系统由与电池和/或超级电容器并联的燃料电池堆组成。 ÉTS 开发的电池将是一个完美的起点，该系统的简化原型将在 ÉTS 电力电子实验室实施，以便准确确定模型参数并验证模型性能。该项目将重点关注负载建模例如 MEA 中的变压器整流器单元 (TRU) 和电动静压执行器 (EHA)。该项目展示了燃料电池在航空领域的新应用，以及燃料电池组件（电极、膜和催化剂）的最新技术进步。 ）和加压氢气罐，燃料电池可以被视为飞机电气系统的潜在来源，该项目不仅在燃料消耗和维护方面对飞机公司有利，而且由于燃料电池产生的电力毒性低，因此对环境也有利。排放。
