Ways of Dealing with Power Regeneration onto an Aircraft Electrical Power System Bus 飞机电力系统总线电源再生的处理方法
发布日期: 2014-01-14
本SAE航空航天信息报告(AIR)考虑了飞机EPS的功率再生问题。我们考虑了一系列处理这种再生电力的方案,并将其分类排列。包括现有解决方案在内的每种解决方案的优缺点。本文给出了代表性电力系统的验证仿真结果,以演示某些解决方案在实践中如何运行,以及如何在再生过程中保持电能质量。本文还强调了对发电系统变更的影响,因为这些变更可能会对部署的解决方案产生影响,并对发动机和辅助设备的设计产生更广泛的影响。本节将回顾概念,不包括电力系统设计的详细讨论。这些概念与更电动的飞机有关,涵盖交流和直流系统,可应用于正常运行条件或故障缓解。
This SAE Aerospace Information Report (AIR) considers the issue of power regeneration into the EPS of an aircraft. A series of options for dealing with this regenerative power are considered and arranged in categories. Advantages and disadvantages of each solution, including the existing solution, are included. Validated simulation results from representative Electrical Power systems are presented in order to demonstrate how some of the solutions may operate in practice and how power quality can be maintained during regeneration. The impact on changes to the electrical generation system are also highlighted in this AIR, as these changes may have an impact on the solution deployed and the wider impact on the design of engines and auxiliaries. This AIR reviews concepts and excludes detailed discussions on power system design. These concepts relate to the More Electric Aircraft, cover both AC and DC systems and can be applied to both normal operating conditions or as fault mitigation.
