Abstract
The invention regards an apparatus for estimating a resonant frequency of a wind turbine tower, comprising a measuring module adapted for measuring acceleration values of the wind turbine tower wherein the acceleration values represent acceleration of the wind turbine tower, a filter module adapted for receiving the measured acceleration values, the filter module comprises a variable filter wherein the variable filter is adapted to attenuate frequencies in a band hereby attenuating frequencies for an output of the filter module, an adaptive algorithm module comprising an adaptive algorithm wherein the adaptive algorithm module is adapted for communicating with the filter module and wherein the adaptive algorithm is adapted to minimize the energy of the output of the filter module by adjusting the band of attenuated frequencies, a resonant frequency estimating module adapted for estimating the resonant frequency of a wind turbine tower based on the attenuated frequencies.
