Sopel M. Monitoring in electric power industry.

3. Object of research: electrical power systems and plants. The purpose of research: theoretical and practical solutions for monitoring in electrical power engineering, creation of universal time system in power industry. Methods of research: set theory for classification of monitored values and discemment of emergency states; matrix method for analysis of three-phase primary measuring converters; logic algebra for pattern recognition; probability theory and mathematical statistics for assessment of short-circuit current's random parameters; physical simulation methods for research and testing of hardware-software systems. Theoretical and practical results: system of terms and concepts in monitoring field has been developed; theory of primary measuring channels has been evolved; mathematical model for recognition of inadequate measured values has been designed for the first time; mathematical model of different relays and their diagnostics tools has been designed for the first time; noise analysis has been made for communication line which has been presented as distorting quadripole, disturbances in transmitted discrete signals have been analyzed; design, development and production of 14 modifications of hardware-software systems "Regina" have been made. Degree of introduction: there are more than 700 hardware-software systems "Regina" on nuclear power plants, hydropower plants, thermal power plants, 330-750 kV "Ukrenergo" substations, regional power supply substations, "Ukrzaliznytsia" traction substations in Ukraine. There are 134 hardware-software systems "Regina" on electrical power objects in other countries, namely Belarus, Moldova, Azerbaijan, Kazakhstan, Georgia. Sphere of use: electrical power systems and objects.
