Trailing Edge Flap

The variation of aeroelastic system dynamics is treated as the change of time-varying aerodynamic loads over rotating wind turbine blade. An Adaptive Control scheme is introduced to suppress blade fluttering, caused by unsteady aerodynamic loads, with trailing-edge flap. The robustness and effectiveness of designed Adaptive Controller are shown by good simulation results. For stability analysis, the proposed Adaptive Stability Theorem is proved theoretically by Kalman-Yacubovic Lemma and also illustrated numerically by certain case.

Vibration of wind turbine blade is one of the major important obstacle to increase the capacity of electricity generation. Particle damping technique is introduced in wind turbine blade to check the vibration suppression. Damper is mounted on blade externally. RPM of blade, position of dampers, are the variable parameters used in this parametric study keeping particle size as 9 mm and percentage fill in damper is 90 %. Experimental test is conducted in all the research work. Without damping results are compared with with-damping results and find out the vibration suppression regions.

Particle damping technique is first time use for study of vibration suppression in 1 kW wind turbine blade for using change of percentage fill of particles parameter. External container is attached on blade and fills the container using three different percentage changes as 10, 50 and 90 using 3mm spherical ball size. Blade is mounted at root location on electromagnetic shaker and accelerometer is located randomly on blade at 600 mm position from tip of blade. With damping results are compared with without damping and finding out the cases where vibration suppression takes place.

Response Curves

Passive control of flapwise vibrations of a wind turbine blade is investigated when a single tuned mass damper (TMD) is attached to the blade. The blade is subjected to a wind pressure which changes linearly with height from the ground level due to the wind shear. The vibrations of the wind turbine blade are theoretically and numerically analyzed to determine the natural frequency diagrams, frequency responses, stationary time histories and their FFT results. It is found that several peaks appear near the specific rotational speeds in the response curves for the blade because of both the wind pressure and the parametric excitation terms. It is also demonstrated that the optimal single TMD can suppress the resonance peaks if the fixed point theorem is used to determine the optimal values of the parameters of the TMD. The influences of the mass and install position of the TMD on its performance are also examined.
