The corresponding cabling is fixed. In this way the loads can be connected to the generator directly over the power feeders. The current level enters the loss calculation quadratically and is the basis for the determination of the cable sizes. Unbalanced currents can cause increased losses and oversizing of the cables.<\/p>\n<p>An intelligent method is developed, which switches loads between the power feeders and thus is able to charge the cables equally. In this way the onboard grid can adapt itself automatically to changing load configurations. As a consequence the cross-sections of the cables and the weight can be reduced.<\/p>\n<p><strong>Advantages:<\/strong><\/p>\n<ul>\n<li>self-configurating system in case of load changes<\/li>\n<li>weight savings by means of smaller cable cross-sections<\/li>\n<li>low voltage drop at the cables<\/li>\n<\/ul>\n<p><img loading=\"lazy\" decoding=\"async\" class=\"size-full wp-image-2859\" src=\"https:\/\/www.hsu-hh.de\/ees\/wp-content\/uploads\/sites\/680\/2020\/04\/31en_Feeder-Balancing_EV.jpg\" alt=\"31en_Feeder Balancing_EV\" width=\"613\" height=\"300\" data-credit=\"HSU \/ EES\" srcset=\"https:\/\/www.hsu-hh.de\/ees\/wp-content\/uploads\/sites\/680\/2020\/04\/31en_Feeder-Balancing_EV.jpg 613w, https:\/\/www.hsu-hh.de\/ees\/wp-content\/uploads\/sites\/680\/2020\/04\/31en_Feeder-Balancing_EV-300x147.jpg 300w\" sizes=\"auto, (max-width: 613px) 100vw, 613px\" \/><\/p>\n<h2>Contact person:<\/h2>\n<p>Prof. <abbr title=\"Doktor der Ingenieurwissenschaften\">Dr.-Ing.<\/abbr> <abbr title=\"habilitatus\">habil.<\/abbr> Detlef Schulz (<u>project manager<\/u>)<br \/>\nDepartment of Electrical Engineering<br \/>\nElectrical Power Systems<\/p>\n<p>Cooperation partner: EADS \/ Airbus Operations <abbr title=\"Gesellschaft mit beschr\u00e4nkter Haftung\">GmbH<\/abbr><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Modern aircraft use an AC and a DC grid for energy transmission.
