wind turbine, pulse infrasound emission, spectrumAbstract
Analysis of the literature that most completely reflects the nature of the occurrence and propagation of the sound emission of wind power engineering facilities is presented. A literature review of studies of pulse sound emission in the geological and air environments has allowed to reduce the concept of emission to the concept of signal, the general theory of signals. Based on the analyzed literature data, the basic principles of assessment of pulse infrasound signal of the wind turbine are formed. Approach in terms of the theory of signals is aimed at the future implementation of the highlighted principles in the mathematical model. The concept of pulse sound signal is applicable to any field of the natural environment around the wind turbine. This is the principle of the signal uniformity in the fields of the natural environment on the one hand and the principle of signal separation in these areas on the other. Evaluation of the amplitude of the biosphere response to the impact of the sound signal of the wind turbine is reduced to the corresponding amplitude-frequency analysis of the action signal. As a result, the calculation of the spectrum of probable and dominant harmonics for the model of FL 2500-100 wind turbine, the application of which is the most relevant in Ukraine is given.
