Abstract (EN): This paper describes the main results obtained with different strategies of instrumentation of a 2.0 MW wind turbine, within the scope of establishing an optimized dynamic monitoring system. The data processing strategy is based on the continuous tracking of the main vibration modes of the instrumented wind turbine using Operational Modal Analysis (OMA) techniques combined with algorithms that deal with the particularities of wind turbines and that permit an online automated identification. Aiming to reduce the investment in monitoring equipment and simultaneously keep and adequate accuracy in structural condition assessment, in this paper, a one year database of continuously collected acceleration time series is used to evaluate 4 alternative layouts for the distribution of the accelerometers along the tower height, using a varying number of installed sensors.
