Hertsyk S. Computerized diagnostics system of components of electrical equipment, considering the modes of its operation.

Object of study: the process of determining the technical condition of the nodes of the electrical equipment based on the measurement and analysis of diagnostic signals generated in the working electrical equipment, considering the modes of its operation. Purpose: to develop models, methods and a computerized system that implements them to diagnose the technical condition of the electrical equipment units, considering both their modes of operation and certain types of defects. Research methods: the methods of information-measuring diagnostic system theory, theory of objects and systems diagnostics, probability theory, and statistical methods of diagnostic signal processing were used to solve these problems. Theoretical and practical results and novelty: the structure of the scheme was developed, the experimental model of the multilevel information-measuring diagnostic system was designed and experimentally tested. The method of presenting training sets in the form of a matrix, whose elements are scattering ellipses corresponding to certain types of defects of individual electrical equipment units and modes of its operation, is proposed. A scheme for constructing training sets on a three-dimensional (3D) matrix is proposed, elements of which contain sets that correspond to separate nodes of the electrical equipment, and their combination forms a separate electrical unit. This approach makes it possible to practically use a multilevel information-measuring diagnostic system to select a certain training set in determining the technical condition of the units of the electrical equipment, considering the modes of its operation. Subject matter and degree of implementation: the main results of the work were implemented at the EURO-RECONSTRUCTION LLC (Darnytska thermoelectric power station -4, Kyiv) and at the AMIKO Group of Companies, Mykolaiv. Scope: information-measuring systems.
