Abstract

MISTURA DE ESTEIRA DE TURBINA EÓLICA MELHORADA. A presente invenção refere-se a método de controle de uma turbina eólica compreendendo um rotor que compreende pelo menos uma primeira pá, o método compreendendo a etapa de variar um fator de indução da primeira pá ao longo do tempo ao alterar dinamicamente um ângulo de passo da primeira pá ao longo do tempo entre um primeiro ângulo de passo e um segundo ângulo de passo enquanto a primeira pá está girando, onde o primeiro ângulo de passo é diferente do segundo ângulo de passo e onde a mudança dinâmica do ângulo de passo ao longo do tempo é controlada de modo que a respectiva posição de rotação da primeira pá na qual a primeira pá está no primeiro ângulo de passo e as respectivas posições de rotação da primeira pá, nas quais, a primeira pá está no segundo ângulo de passo são deslocadas no tempo e o fator de indução variável da pá ocorre em diferentes posições angulares no plano do rotor ao longo tempo, de modo que uma localização e/ou direção de uma esteira formada a jusante da turbina no vento está mudando dinamicamente em relação ao rotor da turbina eólica.
