Frequency analysis of micro wind turbine vibrations using the MUSIC method

Analysis results of vibro-acoustic signals generated by operation of a micro wind turbine that is installed on the roof of Electric Power Institute, Opole University of Technology are presented in the paper. Mast vibrations of the turbine under study have been measured under different weather conditions, i.e. by various wind speeds. A frequency analysis by use of the MUSIC method was performed. Shown results depict changes of frequency components appearing in the spectrum of the measured signals.
