Résumé

The air transport is undergoing a period of transition, responding to recommendations aimed at drastically reducing its polluting emissions. As a result, the electrical energy vector is taking an increasingly important part on board of aircraft, requiring significant changes to the electrical network. The trend is to develop High Voltage Direct Current (HVDC) networks 540VDC / 800VDC to replace the traditional 115VAC / 230VAC electrical system (ATA24) and support the synergy between non-propulsive and propulsive functions. These new aeronautical HVDC architectures may be subject to network quality issues due to the interconnection of many devices driven by power electronics. In particular, instabilities can occur under certain operating conditions, which needs to be anticipated and avoided. This is the purpose of the network specification step, carried out by the aircraft manufacturer. This paper explores the use of Small Gain Theorem to tackle stability issue and to specify the different stakeholders in such a way as to achieve an optimum sizing of the system's components. The proposed methodology tries to provide a relevant response to this subject by linking potential network uncertainties (variable parameters, etc…) to the formulation of the requirement.
