Abstract

Under certain conditions Electro-Mechanical Actuators are able to regenerate, rather than consume electrical power. Within the More Electric Aircraft this possibility must be carefully considered in order to ensure safe and stable operation of the electrical systems. This paper assesses various strategies for the management of regenerated power in the More Electric Aircraft. A range of options are considered and the advantages/disadvantages of each are discussed. This includes considerations of safety and stability but also weight, component minimization, cost and potential utilization of the regenerated energy. Key aspects which are investigated in this paper are the effect of increased DC bus voltage on the management of regenerated energy and an assessment of the feasibility of returning energy to the engine inertia. It is shown that increased DC link voltage has distinct advantages when employed in combination with current architectures. However if a fundamental change to system architecture is utilized then this brings very significant benefits.

多电动飞机机电致动器再生电源管理

在一定条件下，机电致动器能够再生，而不是消耗电力。在更多的电动飞机中，必须仔细考虑这种可能性，以确保电气系统的安全和稳定运行。本文评估了多电动飞机再生动力管理的各种策略。考虑了一系列选择，并讨论了每种选择的优点/缺点。这包括对安全性和稳定性的考虑，也包括重量、部件最小化、成本和再生能源的潜在利用。本文研究的关键方面是直流母线电压升高对再生能量管理的影响，以及评估将能量回馈给发动机惯性的可行性。结果表明，提高直流链路电压与现有结构结合使用具有明显的优势。但是，如果对系统架构进行根本性的更改，则会带来非常显著的好处。
