Title (EN) POWER CONVERTER FOR FULL CONVERSION WIND TURBINE SYSTEMS
(FR) CONVERTISSEUR D'ÉNERGIE DESTINÉ À DES SYSTÈMES DE TURBINE ÉOLIENNE À CONVERSION TOTALE
Abstract:
(EN) Power converters for use in wind turbine systems are included. For instance, a wind turbine system can include a full power generator having a stator and a rotor. The generator is configured to provide a low voltage alternating current power on a stator bus of the wind turbine system. The wind turbine system includes a power converter configured to convert the low voltage alternating current power provided on the stator bus to a medium voltage multiphase alternating current output power suitable for provision to the electrical grid. The power converter includes a plurality of conversion modules, each conversion module comprising a plurality of bridge circuits. Each bridge circuit includes a plurality of silicon carbide switching devices coupled in series. Each conversion module is configured to provide a single phase of the medium voltage multiphase alternating current output power on a line bus of the wind turbine system.
(FR) L'invention concerne des convertisseurs d'énergie destinés à être utilisés dans des systèmes de turbine éolienne. Par exemple, un système de turbine éolienne peut comprendre un générateur d'énergie totale pourvu d'un stator et d'un rotor. Le générateur est configuré de façon à fournir une énergie en courant alternatif basse tension sur un bus de stator du système de turbine éolienne. Le système de turbine éolienne comprend un convertisseur d'énergie configuré de façon à convertir l'énergie en courant alternatif basse tension fournie sur le bus de stator en une énergie de sortie en courant alternatif polyphasé moyenne tension appropriée pour la fourniture au réseau électrique. Le convertisseur d'énergie comprend une pluralité de modules de conversion, chaque module de conversion comprenant une pluralité de circuits en pont. Chaque circuit en pont comprend une pluralité de dispositifs de commutation en carbure de silicium couplés en série. Chaque module de conversion est configuré de façon à fournir une seule phase de l'énergie de sortie en courant alternatif polyphasé moyenne tension sur un bus de ligne du système de turbine éolienne.
