Abstract

"SISTEMA ELéTRICO PARA UMA TURBINA/ALTERNADOR". Apresente invenção se refere a um sistema elétrico para umaturbina/alternador compreendendo uma turbina acionada a gás eum alternador de magneto permanente girando sobre um eixocomum compreende um circuito inversor conectável ou a umcircuito de saída de CA ou ao enrolamento de estator doalternador. Um circuito de controle durante um modo de partida ligao circuito inversor ao enrolamento de estator do alternador edurante um modo de parada liga o circuito inversor ao circuito desaída de CA. Desta forma, durante o modo de partida, o alternadorfunciona como um motor para aumentar a velocidade da turbinaaté uma velocidade de ignição segura e no modo de parada osistema elétrico descarrega para o circuito de saída de CA umaenergia elétrica de CA tendo uma freq³ência não relacionada coma velocidade de rotação do alternador.
