Abstract

resumo patente de invenção: "método de operar uma turbina eólica". a presente invenção refere-se a um método de operar uma turbina eólica compreendendo detectar quando uma primeira pá substancialmente se aproxima da sombra da torre, e ajustar o passo de pelo menos uma outra pá, a qual está em uma posição acima da torre ou se aproximando dela, para aumentar o ângulo de ataque e carga de vento na dita pelo menos uma outra pá de uma tal maneira que um aumento do ângulo de inclinação do rotor é causado. o método compreende adicionalmente detectar quando a primeira pá está substancialmente perto de deixar a sombra da torre, e ajustar o passo da pelo menos uma outra pá para diminuir o ângulo de ataque e carga de vento na dita pelo menos uma outra pá de uma tal maneira que o aumento causado anteriormente do ângulo de inclinação do rotor é cancelado.
