Abstract
Offshore wind power is one of !he fastest growing in !he field of renewable energies. To date, most offshore wind farms have installed fixed wind turbines. Fixed bottom wind turbines are suitable in shallow waters where the curren! technology is quite contrasted. However, in many coastal areas of the world the waters are too deep for this technology. The installation of wind farms in deep water requires the development of innovative solutions that use floating platforms for wind turbines. The present project will contribute in different aspects of the control and monitoring of this type of wind turbines.
The reliability requirements of wind turbine components have increased significantly in recen! years in the search for a lower impact on the casi of energy. However, this process is no! lacking in complexity, as these new designs afien carry the inherent assumption of sorne uncertainty in the loads that is complex to evaluate a priori. In addition, the trend towards larger wind turbines installed in offshore locations has significantly increased !he cost of repair / replacement of !he component. In !he wind industry, therefore, corrective maintenance as well as predictive maintenance (planned befare failure) is crucial far maximum availability. This project intends to continue the research line from previous projects in monitoring systems based on vibration analysis but with new techniques and new sensors that allow the development of accurate and reliable methods of prediction, detection and fault / damage localization.
Although there has been extensive research into the use of conventional control systems (!arque, pitch, etc.) far load reduction in offshore wind turbines, structural damping control devices are a relatively new approach. Over the past 30 years, numerous structural control strategies and devices have been developed to mitigate wind and earthquake loads in civil engineering structures. One of !he main objectives of this project will focus on the development and validation of load reduction and dynamic vibration strategies in floating wind turbines using advanced structural control techniques with specific devices.
In summary, the ultimate goal of the project is !he development and validation of intelligent monitoring systems for the prediction, detection and location of failures / damages in floating offshore wind turbines, as well as the design of pitch control systems, and active and semiactive control systems with specific structural damping devices suitable far floating offshore wind turbines. The project integrates fundamental research with the development of algorithms that take into account practical aspects of its real applicability.
Finally, note that the challenge that the project aims to address is that of Energía segura, eficiente y limpia. In particular, it is in !he wind energy field that this project will contribute (i) solutions far !he adaptation of wind turbines to !he extreme conditions of the offshore environment, (ii) prediction, detection and localization of failures / damages in floating wind turbines, (iii) new control techniques far floating offshore wind turbines.
