Gyzhko I. Systems for technical vibrodiagnostics of power electrical equipment moving parts with autonomic measuring transducers

The object of research: evaluation of technical condition of power electrical equipment moving parts. The purpose of research: development of models, methods and computerized information-measuring system for vibrodiagnostics of power electrical equipment moving parts with autonomic measuring transducers, which provide transmission of diagnostic signals on a radio channel. Methods of research: methods of the theory of information-measuring systems, probability theory, mathematical statistics, theory of diagnostic objects and systems, methods of statistical analysis of diagnostic signals and pattern recognition. Theoretical and practical results and innovations: was created mathematical model of rotary electric machines moving parts; for the created model proved using as diagnostic signs coefficients of asymmetry and kurtosis, the number of vibration process spectrogram peaks; developed and tested a method of diagnosing of power electrical equipment moving parts with specified accuracy and reliability; developed a method of choosing the optimal type of spectral smoothing window; theoretical researched and confirmed of experimental results the errors, caused by transformation of the diagnostic signal, noise exposure and its transmission on a radio channel. A subject and degree of the application: obtained results used as separate blocks and programs in the Group of companies "Amiko" in the general system control and monitoring of the Fuel and Energy Complex, Group of companies "Karbon" for control and monitoring of renewable energetics objects. Effectiveness of implantation: increase the reliability of electrical equipment functioning due to realization diagnostics of technical state with given accuracy and reliability. The sphere of application: systems of technical diagnostics on power generating facilities in Ukraine.
