Abstract
This article presents the results of vibration monitoring of the wind power plant (WPP). The analysis of the vibration effect from the pulsating loads of the tower on the foundation of the wind power plant is given based on the results of field researches. In the automated mode, the actual vibration parameters of the tower foundation were determined. The results of the research are presented by the graphical dependence of the vibration characteristics (frequency, amplitude, acceleration) on the intensity of the wind pressure. An extrapolation of the potential forces arising in the foundation at the maximum wind loads of the area is given. In order to predict the potential stress-strain state of the foundation, the obtained monitoring parameters were used for numerical modeling in the Plaxis 2D software package. The simulation results made it possible to make a prediction of the stress-strain state according to the maximum vibration indices. Recommendations on the choice of the optimal foundation in the engineering-geological and climatic conditions of the wind power plant are also given.
