Abstract
Fault detection and accommodation of faults in wind turbines are important steps in the process of improving the reliability of wind turbines. Previously a number of observer based methods to detect and isolate faults in generator and rotor speed sensors in a wind turbine has been presented. The next step is to use the information of isolated faults to reconfigure the rotor/generator speed measurements feed to the control system as well. In this paper a scheme for accommodating the detected faults is proposed. The scheme is observer based and computes the best generator/rotor speed depending on the available fault free measurements. The scheme is designed for and tested on a bench mark model for fault detection and accommodation of wind turbines. It accommodates the generator and rotor speed faults in the bench mark model well, such that the power production of the wind turbine can continue during the fault.
