| Abstract |
The paper presents fault isolation approach of a
wind power station based on model-based diagnosis. The main
attention is focused on a wind turbine for which the state
equation is formulated. Certain faults occurring in described
turbine blades are represented by change of equation parameters.
The knowledge about the disturbances are obtained from
measured and estimated instantaneous angular velocity of the
shaft. The desired sensitivity assures applied robust observers,
which decouple changes of selected wind engine parameters from
computed outputs. Generated residuals allow to isolate a blade
elasticity and its oscillation damping and damping of the rotation
a drive train. |
