Abstract

"TURBINA EàLICA COM TRANSMISSçO HIDROSTÁTICA". A presente invenção refere-se a uma turbina eólica dotada de um rotor; uma bomba hidráulica acoplada o rotor, dois ou mais motores hidráulicos de deslocamento variável, que são acionados pelo fluxo de fluido a partir da bomba hidráulica, pelo menos, um gerador acoplado aos motores hidráulicos de deslocamento variável e um óleo de circuito de óleo hidráulico de ciclo fechado para o transporte de óleo pressurizado a partir da bomba hidráulica para os motores e para o retorno do óleo para a bomba a partir dos motores. Um controlador no circuito de óleo hidráulico de ciclo fechado controla o fluxo de óleo no circuito de circuito de ciclo fechado e deslocamento em cada um dos motores hidráulicos de deslocamento varável. O controle de fluxo dentro e fora do motor para cada rotação daquele motor controla o fluxo para a bomba hidráulica, que tem um deslocamento fixo, controlando assim a sua rpm, controlando desse modo a rpm do rotor. Um acumulador hidráulico pode ser fornecido no ciclo fechado.
