Title
(EN) SYSTEM FOR CONVERTING AND TRANSPORTING ELECTRICAL ENERGY FOR THE INTERNAL HYBRIDISATION OF AN AIRCRAFT WITH TURBOJET ENGINES
(FR) SYSTEME DE CONVERSION ET DE TRANSPORT D'ENERGIE ELECTRIQUE POUR L'HYBRIDATION INTERNE D'UN AERONEF A TURBOREACTEURS
Abstract
(EN)
In an aircraft propelled by at least one turbojet engine from which power can be drawn or into which power can be injected via a high-pressure (100, 120) and/or low-pressure (102, 122) turbine shaft and comprising at least one gas turbine for ensuring power transients, a system for converting and transporting electrical energy is provided in which each of the high- and/or low-pressure turbine shafts is connected to a first dual-feed asynchronous machine (48, 50, 52, 54) delivering a first three-phase AC voltage to an AC distribution network (46) and a second polyphase AC voltage for a first bidirectional AC/DC converter (56, 58, 60, 62) supplying DC voltage to a DC distribution network (64), at least one second bidirectional DC/AC converter (66, 68) connected to the DC distribution network transforming this DC voltage into a third polyphase AC voltage supplying at least one second dual-feed asynchronous machine (70, 72) engaged with a rotation shaft (140, 160) of the gas turbine, the second dual-feed asynchronous machine further delivering a fourth polyphase alternating voltage to the AC distribution network.
(FR)
Dans un aéronef propulsé par au moins un turboréacteur sur laquelle on peut prélever ou injecter de la puissance via un arbre de turbine haute pression (100, 120) et/ou basse pression (102, 122) et comportant au moins une turbine à gaz pour assurer des transitoires de puissance, il est prévu un système de conversion et de transport d'énergie électrique dans lequel chacun des arbres de turbine haute et/ou basse pression est relié à une première machine asynchrone à double alimentation (48, 50, 52, 54) délivrant d'une part une première tension alternative triphasée sur un réseau de distribution AC (46) et d'autre part une deuxième tension alternative polyphasée pour un premier convertisseur bidirectionnel AC/DC (56, 58, 60, 62) fournissant une tension continue sur un réseau de distribution DC (64), au moins un second convertisseur bidirectionnel DC/AC (66, 68) relié au réseau de distribution DC transformant cette tension continue en une troisième tension alternative polyphasée alimentant au moins une seconde machine asynchrone à double alimentation (70, 72) en prise avec un arbre de rotation (140, 160) de la turbine à gaz, la seconde machine asynchrone à double alimentation délivrant en outre une quatrième tension alternative polyphasée sur le réseau de distribution AC.
