Development of an algorithm to detect shifts in low frequency signals after few cycles to asses the condition of wind turbine fundaments
Abstract
The lifetime of wind power plants is limited by failure risks of building and power plant components. Subject of the project are the foundations of wind turbines, which are subjected to high number of oscillating loads during operation. The project partner carries out vibration measurements on foundations. These should be used to characterize the current state. It is believed that fatigue damage caused by vibratory stress is reflected in a change in vibration behavior. The work undertaken at BOKU deals with the analysis of the measured velocity time series. A new algorithm shall automatically obtaine characteristic values of the measured signals, which allow an analysis of the condition of the foundation.
