Title
(EN) DRIVE CHAIN COMPRISING A DOUBLY-FED ELECTRIC MACHINE AND A BAND-STOP FILTER CONNECTED BETWEEN AN INVERTER AND THE ROTOR OF THE MACHINE
(FR) CHAINE D'ENTRAINEMENT COMPRENANT UNE MACHINE ELECTRIQUE DOUBLEMENT ALIMENTEE ET UN FILTRE COUPE-BANDE CONNECTE ENTRE UN CONVERTISSEUR CONTINU-ALTERNATIF ET LE ROTOR DE LA MACHINE
Abstract
(EN)
The invention relates to a drive chain (16) comprising an electric machine (18) including a rotor (22) and a stator (20), the stator (20) being electrically connected to an alternating grid (12) and having a stator frequency, and a bidirectional system (24) for converting an alternating current into another alternating current. The conversion system (24) is connected between the grid (12) and the rotor (22), and comprises an ac/dc converter (34) connected to the network (12), and an inverter (36) connected between the ac/dc converter (34) and the rotor (22), the inverter (36) and the rotor (22) being interconnected at an intermediate point (28) for each phase of the alternating voltage. The drive chain (16) comprises a band-stop filter (26) for a target interval of between 0.6 times the stator frequency (fstator) and 1.4 times the stator frequency, said band-stop filter (26) being connected between the intermediate points (28) and attenuating the voltage at the intermediate point (28) for the frequencies of the target interval.

Cette chaîne d'entraînement (16) comprend une machine électrique (18) comportant un stator (20) et un rotor (22), le stator (20) étant relié électriquement à un réseau alternatif (12) et présentant une fréquence statorique, et un système bidirectionnel (24) de conversion d'un courant alternatif en un autre courant alternatif. Le système de conversion (24) est connecté entre le réseau (12) et le rotor (22), et comporte un convertisseur alternatif-continu (34) connecté au réseau (12), un convertisseur continu-alternatif (36) connecté entre le convertisseur alternatif-continu (34) et le rotor (22), le convertisseur continu-alternatif (36) et le rotor (22) étant, pour chaque phase de la tension alternative, reliés entre eux en un point intermédiaire (28). La chaîne d'entraînement (16) comprend un filtre coupe-bande (26) pour un intervalle cible compris entre 0,6 fois la fréquence statorique (fstator) et 1,4 fois la fréquence statorique, le filtre coupe-bande (26) étant connecté entre les points intermédiaires (28), et propre à atténuer la tension au point intermédiaire (28) pour les fréquences de l'intervalle cible.
