Methods of signal analysis for vibration control at hydropower plants
Development of vibration condition monitoring system of hydraulic unit on the basis of wavelet transform allows efficient controlling of equipment in the operating mode and has several advantages over spectral analysis. The use of wavelet transform includes not only vibration analysis that aims to define in time interval moment of change in the state of equipment but also to predict the time for its development. This increases effectiveness of detecting defects at an early stage of development, which is very important in the case of hydroelectric power plant as such analysis provides more flexibility in avoidance of hydraulic units malfunctioning prevention.
