Abstract

sistema e método para inspeção baseada em solo de pás de turbina eólica. um sistema e método de inspeção de pás de turbina eólica baseada em solo consistem em uma câmera de imageamento térmico configurada para detectar defeitos de propagação ao obter dados de imageamento térmico de uma pá de turbina eólica quando ela está substancialmente em equilíbrio térmico com relação ao ar circundante e analisar os dados de imageamento térmico com um processador para identificar efeitos térmicos associados com defeitos latentes causados por atrito interno por causa de tensões gravitacionais cíclicas e cargas de vento durante operação normal de turbina. o sistema permite que defeitos latentes sejam identificados usando uma inspeção no local baseada no solo antes de ficarem aparentes visualmente, o que permite que reparos sejam feitos de forma econômica enquanto a pá está no lugar.
