Abstract:
Since 2005 ECN is developing a system for low cost load monitoring of wind turbines. The system is based on optical fibres and provides a solution to wind farm operators determine the accumulated loads and consumed lifetime of their turbines. The system that is being developed by ECN is called Fibre Optic Blade Monitoring (FOBM) and consists among others of a newly and patented sensor with fibre Bragg gratings, an interrogator with a measurement computer, and software for data processing to provide key figures, statistics, and graphs to operators of wind farms for O&M optimisation. As part of the D OWES project (Dutch Offshore Wind Energy Services) ECN has been working on the development of the individual components and the system integration. This report describes the specifications of the entire system and its sub systems and the results of activities carried out in the D OWES project. The developments have shown that the FOBM prototype meets most of its specifications.
