Tests performed on the 2 MW Tvind WECS
Abstract
Results from a 16-channel monitoring program on the Tvind 2 MW wind turbine are presented. The WECS has a rotor diameter of 54 m, three blades, operates downwind, has a cone angle of 9 deg, a tilt angle of 4 deg and each blade is constructed of glass-fiber reinforced epoxy. The blades were monitored for strain angular velocity, and position, the shaft for torque, and additional data were gathered on the linear acceleration of the nacelle, the wind speed at hub height, and the wind direction relative to the rotor. A difference in the center of mass of one of the three blades was detected during the torque measurements. The blade was also observed to experience tensile and compressive stresses, with variations due to gravitational forces. Measurements of the tower wake effect on the torque and blade strains were not possible.
