Abstract

MÉTODO PARA MONITORAR O ESTADO DE INTEGRIDADE DO FIXADOR DA RAIZ DA PÁ, SISTEMA PARA MONITORAR O ESTADO DE INTEGRIDADE DO FIXADOR DA RAIZ DA PÁ E TURBINA EÓLICA. A invenção provê um método para monitorar o estado de integridade do fixador da raiz da pá, compreendendo as seguintes etapas: obtenção de uma sequência de sinais de aceleração representando a vibração lateral da nacele e de uma sequência de sinais de velocidade de rotação representando a velocidade de rotação do rotor; análise da sequência de sinais de aceleração e da sequência de sinais de velocidade de rotação, para determinar a amplitude da nacele no dobro da frequência da velocidade de rotação do rotor; e determinação do estado de integridade do fixador da raiz da pá com base na amplitude. A invenção também provê um sistema para monitorar o estado de integridade do fixador da raiz da pá. Através da presente invenção, o estado de integridade do fixador da raiz da pá pode ser determinado com baixo custo e alta precisão, melhorando assim a eficiência da operação e a segurança de operação da turbina eólica.
