Offshore Wind Turbine Tower Fore-Aft Fatigue Load Reduction by Coupling Control and Vibrational Analysis
نویسندگان
چکیده
The present study proposes a novel tower-control technique that couples linear control feedback theory with an online time-frequency analysis of the tower vibrations, with the aim to widen the research area of situational control of wind turbines. Numerical simulations were conducted for two 5MW-class offshore wind turbines, and the performance of the proposed control method has been tested in terms of fatigue load reduction and actuator activity, and it has been cross-checked against similar results obtained via state-of-the-art tower control. The results indicated that the proposed approach could achieve a more sustainable compromise between the need to alleviate fatigue loads while preserving actuator serviceability.

Fatigue load estimation and reduction for wind turbine
Introduction Fatigue is the structural damage that leads the components of a wind turbine to sudden brittle failure when it suffers cyclic loading [15]. As the size of wind turbines is growing, fatigue loads become more and more significant for the design of major structural components. Concerning fatigue in a wind turbine tower, the fore-aft tower foot bending moment is considered as the most ...

Individual blade pitch state space (IBP SS) control and disturbance accommodating control (DAC) that reject wind speed perturbations are applied on a 5 MW wind turbine mounted on the barge and tension leg floating platforms for performance comparison in above rated wind speed region. The DAC used in this study is simply an IBP SS controller with a wind speed disturbance rejection component. For...

A disturbance accommodating controller (DAC) to reject wind speed perturbations is applied on a 5MW wind turbine mounted on a tension leg platform (TLP). Multi-blade coordinate (MBC) transformation is used to address the periodicity of the floating wind turbine system. A method to apply DAC after applying MBC transformation is developed and several implementation options are presented. Simulati...
متن کاملComputationally Inexpensive Approach for Pitch Control of Offshore Wind Turbine on Barge Floating Platform
Offshore floating wind turbine (OFWT) has gained increasing attention during the past decade because of the offshore high-quality wind power and complex load environment. The control system is a tradeoff between power tracking and fatigue load reduction in the above-rated wind speed area. In allusion to the external disturbances and uncertain system parameters of OFWT due to the proximity to lo...
متن کاملDynamics and Control of Lateral Tower Vibrations in Offshore Wind Turbines by Means of Active Generator Torque
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 proposes the modeling and control of lateral tower vibrations in offshore wind turbines using active generator torque. To implement the active control algorithm, both th...
