Data analysis method for wind turbine dynamic response testing

The authors describe the Wind Data Analysis Tool Set (WINDATS), an analysis package that has proved to be a useful tool for efficiently processing large amounts of test data in a timely manner. WINDATS has been written as a collection of tools that fall into two general groups. First, the preparatory tools perform subsection, filtering, decimation, preaveraging, scaling, and derivation of new channels. Second, analysis tools are used for mean removal, linear detrending, azimuth averaging and removal, binning, and spectral analysis. The input data file can be a standard ASCII file as is generated by most data acquisition software
