Abstract

"INSTALAçãO DE ENERGIA EóLICA". A invenção se refere a uma instalação de energia eólica, de grande porte. Enquanto as lâminas de rotor que são otimizadas para prover para saída máxima pode ser facilmente produzida para instalações menores e podem ser transportadas sem problemas, lâminas de rotor para instalações maiores têm duas desvantagens. A superfície muito grande do rotor produz cargas muito altas na base da lâmina do rotor em altas velocidades do vento de modo que a instalação de energia tenha que ser desligada. Essas cargas muito altas requerem um projeto específico (dimensionamento) da instalação de energia eólica inteira. A segunda desvantagem consiste na produção de uma lâmina de rotor com profundidade de lâmina muito grande. O objetivo da invenção é de eliminar os problemas acima mencionados e simplificar a produção de uma instalação de energia eólica bem como sua operação. Para esta finalidade, a instalação de energia eólica é provida com pelo menos dois rotores dispostos um após o outro, dos quais o primeiro rotor, o qual está disposto à frente do segundo rotor, apresenta um diâmetro menor do que o do segundo rotor.
