Optimisation des Canalisations Electriques et des Armoires de Distribution

Abstract : Power busbars, busways, trunkings and more generally all kinds of interconnections are the bare bones of all electrical networks. These devices should be fully ‘transparent' but their design shows a lack of optimization regarding to energy efficiency. Optimal behavior is obtained when the voltage does not drop, i.e. neither Joule losses nor frequency induced reactive power occur therein.
In order to adapt the design to such phenomena (through a dedicated CAD tool), a natural modeling method is introduced. Whereas finite element methods comply with electromechanical actuators, the so-called PEEC (Partial Element Equivalent Circuit) modeling method is more efficient for interconnections.
Through couplings with optimizers, this method is able to optimize the design of multi-conductor systems, both by adapting their layout to avoid proximity effects, or –as shown here- by defining a cross-section shape compliant with skin effects. Reachable savings are huge as optimization margins are often up to here unexplored. As busbars are also often enclosed in a steel shielding, an extension of the PEEC method –named ‘µPEEC'– is developed to consider magnetization in ferromagnetic part.
The definition of optimization objectives is oriented regarding to life cycle analysis and to considering minimum environmental impact. Optimization earnings are extrapolated regarding to those criteria.
