Abstract

o objeto da presente invenção é um método para determinar e controlar o ângulo de ataque da pá de turbina eólica de velocidade fixa com o objetivo de descobrir um ângulo de ataque apropriado para a extração ótima da energia eólica a baixa e média velocidade do vento, que compreende três etapas: 1 parâmetros básicos da turbina, incluindo o comprimento e a largura da pá, a velocidade de rotação fixa, a velocidade calculada do vento, a velocidade de arranque e a velocidade mais baixa à qual a turbina é forçada a parar e a relação com a potência desperdiçada; 2 - definir a velocidade do vento com base na qual um conjunto de ângulos de ataque pode ser calculado para formar um ângulo de ataque óptimo global da pá de turbina eólica; e 3 - calcular os parâmetros físicos necessários para obter o método mais eficaz de controlar a pá da turbina; esta invenção é aplicável a fabricação de turbinas eólicas de velocidade fixa que podem ser diretamente ligadas à rede, tornando os custos de energia eólica tão baixos como os de outras fontes de energia convencionais.
