Lateral tower vibrations of offshore wind turbines are normally lightly damped, and large amplitude vibrations induced by wind and wave loads in this direction may significantly shorten the fatigue life of the tower. This paper
Emerging trends in the vibration control of both onshore and offshore wind turbines are presented. Passive, active and semi-active structural vibration control algorithms have been reviewed. Of the existing controllers, two control
(v) Wind rotor and tower coupling vibration: The main vibration of large wind turbine is the coupling vibration of wind rotor and tower. The inherent frequency of tower is mainly related
Vortex-induced vibration (VIV) of wind turbine tower is a common occurrence in practical engineering, significantly impacting the safety and reliability of structure. An effective method is developed to investigate the VIV characteristics of a wind turbine tower with an elastic foundation and a lumped mass.
Passive vibration control strategies Passive control techniques are widely adopted to suppress the vibration of the wind turbine tower since no external power is needed and generally speaking their configurations are much simpler compared to the other control methods.
Emerging trends in the vibration control of both onshore and offshore wind turbines are presented. Passive, active and semi-active structural vibration control algorithms have been reviewed. Of the existing controllers, two control schemes, active pitch control and active tendon control, have been discussed in detail.
The tower vibration model developed was further used for spotting out blades angle irregularity, which is a common error that needed to be fixed in other to hence the performance of the wind turbine and help to eliminate or reduce fatigue damages.
The vibration frequency is the natural frequency of the wind turbine tower when the wind speed is 8 m/s, which is located in the frequency lock-in range. Fig. 4. The comparisons of displacement–time histories of the top of the wind turbine tower calculated by theoretical and numerical methods.
Vibration analysis and control of the tower is one of the tasks that must be carried out in the design process of wind turbines [ 11 ].
