摘要

本研究旨在详细设计飞机半跨和全跨的电力系统架构，以及飞机EPS中的能量管理系统，以在适当的时间运行燃料电池、电池组和超级电容器。在飞机上，与超级电容器配合使用一个适当额定功率的燃料电池作为交流总线的APU。电池组通过双向DC - DC转换器连接到直流母线，该转换器作为APU，用于动态响应更快的低功率高优先级直流负载，并满足紧急情况下这些负载的电力需求。在正常工作条件下，电池可以不断地从燃料电池中充电。分析了系统在正常和紧急情况下随载荷随机变化的飞行周期内的响应。这项研究旨在利用燃料电池、电池组和超级电容器的最佳质量来发挥飞机上APU的作用。在适当的额定功率下实现了这三种方法，并开发了一种能量管理系统，用于大负载时使用燃料电池，用于突然负载变化时使用超级电容器，用于小负载变化时使用电池组。

Energy Management System for a Multi-Source Electric Power System Architecture in More Electric Aircraft

This research paper intends to present a detailed design of electric power system architecture of half- and full-span of an aircraft and the energy management system in aircraft EPS to operate fuel cells, battery stacks, and supercapacitors at appropriate times. A fuel cell of appropriate power rating is used as APU for the AC bus in the aircraft in conjunction with a supercapacitor. A battery stack is connected to the DC bus through a bidirectional DC to DC converter which acts as APU for the low-power high-priority DC loads with faster dynamic response and caters to the power needs of these loads under emergency conditions. The battery keeps getting charged from fuel cell under normal operating conditions. The system response is analyzed over a flight cycle with randomly changing load under normal and emergency conditions. The research is intended to use the best qualities of fuel cells, battery stack, and supercapacitors for the role of the APU in an aircraft. All three of them at proper power ratings are implemented and an energy management system is developed to use fuel cell for major loads, supercapacitor for sudden load changes, and battery stacks for minor load changes.

期刊介绍： This journal is only available online from 2011 onwards. Fuel Cells — From Fundamentals to Systems publishes on all aspects of fuel cells, ranging from their molecular basis to their applications in systems such as power plants, road vehicles and power sources in portables. Fuel Cells is a platform for scientific exchange in a diverse interdisciplinary field. All related work in -chemistry- materials science- physics- chemical engineering- electrical engineering- mechanical engineering- is included. Fuel Cells—From Fundamentals to Systems has an International Editorial Board and Editorial Advisory Board, with each Editor being a renowned expert representing a key discipline in the field from either a distinguished academic institution or one of the globally leading companies. Fuel Cells—From Fundamentals to Systems is designed to meet the needs of scientists and engineers who are actively working in the field. Until now, information on materials, stack technology and system approaches has been dispersed over a number of traditional scientific journals dedicated to classical disciplines such as electrochemistry, materials science or power technology. Fuel Cells—From Fundamentals to Systems concentrates on the publication of peer-reviewed original research papers and reviews.
