Abstract

Recently, the aviation industry has witnessed a technological shift towards the More-Electric Aircraft (MEA) concept, driven by reduced fuel-burn and efficiency benefits. This trend of incremental electrification has brought along benefits such as reductions in weight and volume, performance optimization and reduced life-cycle costs for the aircraft operator. It has however also increased the necessary engine power off take and has made the electrical networks of modern MEA larger and more complex. In pursuit of new, more efficient electrical architectures, paralleled or interconnected generation is thought to be one platform towards improved performance and fuel savings. This paper discusses the historical background and associated challenges of paralleled generation and evaluates through modelling and simulation, the compliance of potential solutions to the airworthiness and power quality standards. It concludes by examining the impact of network protection system and extent of standards compliance on the competitiveness of these potential solutions.

民用飞机并联发电符合标准的研究

最近，航空业见证了向更电动飞机(MEA)概念的技术转变，以减少燃油消耗和提高效率。电动化的发展趋势为飞机运营商带来了诸多好处，如重量和体积的减少、性能的优化以及生命周期成本的降低。然而，它也增加了必要的发动机断电，并使现代MEA的电气网络更大、更复杂。为了追求新的、更高效的电气架构，并联或互联发电被认为是提高性能和节省燃料的一个平台。本文讨论了并联发电的历史背景和相关挑战，并通过建模和仿真评估了潜在解决方案对适航性和电能质量标准的遵从性。最后，研究了网络保护系统的影响和标准遵守程度对这些潜在解决方案的竞争力。
