GAS TURBINE GENERATION SYSTEM

A gas turbine generation system has a three-phase generator whose rotor is mechanically coupled to a gas turbine. The system comprises a three-phase voltage balancing circuit having elements independently operable for each phase to disperse or cancel unbalanced components of three-phase current, dur...

Zusammenfassung:	A gas turbine generation system has a three-phase generator whose rotor is mechanically coupled to a gas turbine. The system comprises a three-phase voltage balancing circuit having elements independently operable for each phase to disperse or cancel unbalanced components of three-phase current, during unbalanced fault in a power grid connected to the generator, result in balancing of the three-phase voltage; and the voltage balancing constitutes a mechanism of avoiding the occurrence of the rotor vibration from mechanical resonance points on turbine blades. L'invention concerne un système de génération à turbine à gaz qui a un générateur triphasé dont le rotor est mécaniquement accouplé à une turbine à gaz. Le système comprend un circuit d'équilibrage de tension triphasée ayant des éléments actionnables indépendamment pour chaque phase pour disperser ou annuler les composantes déséquilibrées de courant triphasé, pendant un défaut déséquilibré dans un réseau électrique connecté au générateur, entraînant l'équilibrage de la tension triphasée ; et l'équilibrage de tension constitue un mécanisme servant à éviter l'apparition de vibrations du rotor à partir de points de résonance mécanique sur les pales de la turbine.
