Abstract

''INSTALAçãO DE ENERGIA EóLICA''. Instalações de energia eólica geralmente têm um acionamento ativo para o rastreamento de direção do vento. O acionamento ativo gira o alojamento de máquina da instalação de energia eólica, de uma tal maneira, que as laminas de rotor do rotor são orientadas na direção do vento. Este acionamento, o qual é requerido para finalidades de rastreamento da direção do vento, é geralmente um acionamento azimutal, o qual é usualmente disposto, com os suportes azimutais associados, entre o topo da torre e o alojamento de máquina. Um acionamento de deslocamento é suficiente, quando estão envolvidas pequenas instalações de energia eólica, enquanto maiores instalações de energia eólica são geralmente equipadas com uma pluralidade de acionamento azimutais. O objetivo da invenção é o de aperfeiçoar o acionamento azimutal para instalações de energia eólica, de modo que os problemas, acima mencionados, são eliminados, provendo uma acionamento azimutal estruturalmente simples, assegurando distribuição de carga uniforme para cada acionamento azimutal, e prevenindo flutuações de torque indesejadas nos acionamentos individuais. Uma instalação de energia eólica compreendendo um alojamento de máquina, o qual acomoda um rotor com ao menos uma lâmina de rotor e um dispositivo de deslocamento para o deslocamento do alojamento de máquina para a orientação desejada do rotor na direção do vento, sendo que o dispositivo de deslocamento tem, como seu acionamento (1), um motor assíncrono de três fases, o qual, para o deslocamento do alojamento de máquina, é atuado por uma corrente de três fases e é, temporalmente ou completamente, atuado com corrente direta durante o tempo de paralisação do alojamento de máquina.
