Hydraulic Units’ Vibration Diagnostics Subsystem Improvement and its Impact on the Level of Technogenic Risks

The paper focuses on new methods of hydro power plant vibrodiagnostics, which would allow increasing the quality of prevention measures for technogenic catastrophes. The paper assumes that the introduction of monitoring systems requires large investments, and henceforth the use of various methods of data processing is encouraged in order to provide a higher economic efficiency of monitoring. The paper considers the possibility of analyzing vibrodiagnostical data using wavelet transform, and estimates the comparative advantages of this method over traditional ones. To make conclusions, anevaluation of technogenic risks is provided before and after the improvement of monitoring systems to emphasize the necessity of applying the wavelet analysis based method.
