Matrix approach based on Quadripole for quality analysis in Aircraft Electrical Power Distribution System

Résumé

HVDC bus based electrical network architectures have shown to be relevant for More-Electric Aircraft. Today, adequate standards of power quality and stability must be set and even optimized: subsequent design constraints have to allow the system integrator to guarantee the safe operation of the network, without excessive impact on the design of the equipment provided by the suppliers, especially regarding weight penalty. In this context, this paper proposes a specific methodology to analyze the power quality constraints in an HVDC network. A matrix approach, based on Quadripole analysis of the power distribution is considered. It aims at achieving a direct sensitivity analysis of any quantity (regarding its harmonic content) of any electrical network with respect to selected inputs and based on the network topology and parameters. One major advantage of this methodology is that the modeling approach is analytically developed, based on symbolic calculation. All the devices (sources, cables, filters, loads, etc) of the system are represented as four-terminal (quadripole) devices, connected together according to the network topology. The calculations are performed at very high speed in the frequency domain. An application of this approach on a relevant aircraft electrical power distribution is shown to highlight its benefit on the path of optimizing new HVDC quality standards.
