Proposta de Controle de Yaw em Aerogeradores Baseado em Dados de Campo

The present work proposes three variations of yaw control systems and makes a comparative analysis of net generated energy gain and actuation number. The three yaw control system proposals are compared with two ideal controls. One in which the actuator is assumed to operate following the wind direction instantaneously without any limitation and the other with speed limitation. Controls were modeled and compared using one second field measurement data. The results indicate that, among the proposed variations, the one that presented the highest net energy gain is also the one with the highest number of actuations, concluding that there is a relationship between energy gain and number of actuations.
