Abstract

MéTODO E DISPOSITIVO PARA MONITORAR O ESTADO DE LáMINAS DE ROTOR EM INSTALAçõES DE ENERGIA EóLICA. A presente invenção refere-se a um método e um dispositivo para monitorar o estado das lâminas de rotor em instalações de energia eólica. De acordo com a invenção, o ruído produzido pelas estruturas é medido por meio de pelo menos um sensor de deslocamento disposto na lâmina de rotor, os sinais de saída dos ditos sensores determinam um espectro de freqüência em uma unidade de avaliação por meio de métodos adequados, o espectro de freqüência é comparado aos espectros de referência correspondentes aos estados definidos de danos e outros estados específicos e armazenados na unidade de avaliação, e o estado da lâmina de rotor é determinado a partir dos mesmos. O objetivo da invenção é proporcionar um método e um dispositivo que possibilitem danos locais internos e externos existentes, e outros estados causadores de danos específicos das lâminas de rotor, a serem rapidamente identificados e avaliados, a fim de contar para o efeito do mesmo na operação da instalação de uma maneira automatizada. Para finalizar, o ruído conduzido por estruturas é medido a partir de uma seqüência de medições individuais realizadas, diretamente, uma após a outra, sendo o início de cada uma das ditas medições individuais disparadas de acordo com um ângulo rotacional uniforme da lâmina de rotor em relação ao eixo geométrico rotacional do rotor, e todos os espectros de freqüência determinados de cada medição individual são acumulados antes de serem comparados com os espectros de referência.
