  • Comparative analysis of infrasound noise emitted by wind turbines of various power

    Tomasz MALEC, Tomasz BOCZAR, Daria WOTZKA

    The subject area of this paper is infrasound signals generated by work of modern wind turbines. A comparative analysis of the measurement results of the infrasound noise generated by two types of high-power wind turbines i.e. REPOWER MM92 of electric power 2 MW and Vensys 62 of electric power of 1.2 MW is presented in the paper. The first studied turbine is brand new and the other has been in operation for five years. The aim of the analyzes was to determine the frequency spectra of the recorded infrasound signals and to calculate the corresponding. For comparative purposes, the characteristics presented in this paper, were calculated separately for the analyzed turbines taking into account three selected values of wind speed. On the basis of the obtained results the influence of wind speed changes on the generated levels of low-frequency acoustic signals was determined. Then, the dependencies obtained from measurements were referred and compared to the limits defined in the appropriate standards.
