Full Scale Test of trailing edge flaps on a vestas v27 wind turbine active load reduction and system identification
Wind Energy, 2014Co-Authors: Damien Castaignet, Thomas Buhl, Jens Jakob Wedelheinen, Niels Kjolstad Poulsen, Thanasis K Barlas, Niels Anker Olesen, Christian Bak, Taeseong KimAbstract:A Full-Scale Test was performed on a Vestas V27 wind turbine equipped with one active 70 cm long trailing edge flap on one of its 13 m long blades. Active load reduction could be observed in spite of the limited spanwise coverage of the single active trailing edge flap. A frequency-weighted model predictive control was Tested successFully on this demonstrator turbine. An average flapwise blade root load reduction of 14% was achieved during a 38 minute Test, and a reduction of 20% of the amplitude of the 1P loads was measured. A system identification Test was also performed, and an identified linear model, from trailing edge flap angle to flapwise blade root moment, was derived and compared with the linear analytical model used in the model predictive control design model. Flex5 simulations run with the same model predictive control showed a good correlation between the simulations and the measurements in terms of flapwise blade root moment spectral densities, in spite of significant differences between the identified linear model and the model predictive control design model.

frequency weighted model predictive control of trailing edge flaps on a wind turbine blade
IEEE Transactions on Control Systems and Technology, 2013Co-Authors: Damien Castaignet, Thomas Buhl, Ian Couchman, Niels Kjolstad Poulsen, Jens Jakob WedelheinenAbstract:This paper presents the load reduction achieved with trailing edge flaps during a Full-Scale Test on a Vestas V27 wind turbine. The trailing edge flap controller is a frequency-weighted linear model predictive control (MPC) where the quadratic cost consists of costs on the zero-phase filtered flapwise blade root moment and trailing edge flap deflection. Frequency-weighted MPC is chosen for its ability to handle constraints on the trailing edge flaps deflection, and to target at loads with given frequencies only. The controller is first Tested in servo-aeroelastic simulations, before being implemented on a Vestas V27 wind turbine. Consistent load reduction is achieved during the Full-Scale Test. An average of 13.8% flapwise blade root fatigue load reduction is measured.
