METHOD AND SYSTEM OF WIND TURBINE CONDITION MONITORING

The invention relates to a method of condition monitoring of a wind turbine. Measurement data and operating condition parameters are captured. A subset of the operating condition parameters is selected. A set of n characterizing moments is calculated based on the subset of operating condition parameters. A finite n-dimensional space each representing possible values for one of the characterising moments is provided. The n-dimensional space is sub-divided into a number of bins each representing a n-dimensional interval defined by n one-dimensional intervals. Each one- dimensional intervals represents an interval in one of the n dimensions. Each bin defines an acceptable range for the set of n characterizing moments. The set of the characterising moments is determined if it belongs to one of the bins. The set of the characterising moments and measurement data are accepted if the set of the characterising moments belongs to one of the bins.
