Mazmanian R. 22D Monitoring in the Systems of Technical Diagnostics and Conditions Testing of Electric Power Equipment.

Study object: technical diagnostics and conditions testing of electric power equipment. Research aims: to develop a 2D monitoring concept and methodology for technical diagnostic systems; to extend the theoretical background for one and two-dimensional few-elements data processing; to elaborate novel research and construction methods of data acquisition for conditions testing and diagnostics of electric power equipment computer systems. Research methods: the theoretical part relies on the analytical and numerical methods with implementation of probability and set theories as well as mathematical statistics, theories of circuits and automatic control, pattern recognition and digital signal processing. Computer modeling and calculation experiments are used in practical part. Theoretical and practical results and innovations: the acute theoretical and empirical problem of 2D monitoring in the systems of electric power equipment conditions testing and technical diagnostics for early error manifestation detection, localization and progress prediction was solved. The novel methods aimed to increase reliability, performance and measurement accuracy of diagnostic parameters, to reveal the hidden information and reduce its redundancy as well as methods of machine perception of dynamic images and parametric fields scenes were elaborated. Implementing these methods in the systems of technical diagnostics and conditions testing ensures their portability within the same type of power equipment. Subject and degree of application: the main results are implemented in the following institutions and organizations – Institute of electrodynamics of NAS of Ukraine (NASU), Walker Hagou B.V. (Holland), G. V. Kurdyumov Institute for Metal Physics (IMP) of the NASU, MVTP "Ecomtech”. Efficacy of application: the permanent magnets testing systems have been developed, along with the systems aimed for diagnostics and non-destructive testing of products, nuclear power components and constructs as well as ultrasonic thermal profile and thermal stress monitoring system in the pressurized-water nuclear reactors. Area of application: diagnostics and information measuring systems.
