Information × Registration Number 0218U005060, 0115U002529 , R & D reports Title Development of theoretical foundations for improving the energy efficiency of electrical facilities, developing diagnostic methods and systems for correcting energy consumption and energy conversion during operation and in emergency conditions popup.stage_title Head Mykhailo Zagirnyak, Registration Date 16-02-2018 Organization Kremenchuk Mykhailo Ostrohradskyi National University popup.description2 As a result of the implementation of the stages of scientific research: 1) a methodology was developed for the evaluation and management of energy transformation processes in the energy channel of electrical facilities, which, unlike existing ones, allows us to identify the diagnostic features of emergency situations in the operation of equipment with an energy criterion and offer a complex of organizational and technical means, which will ensure an increase in the energy manageability of electrical facilities. 2) The method for identifying the parameters of the electrotechnical complex is developed, in contrast to existing ones, it is based on the compilation of energy models in the form of equations for the balance of the harmonic power components between the power source and the energy channel elements, and allows to expand the number of unknown parameters of the replacement circuit. 3) The method for diagnosing asynchronous motors is developed, in contrast to existing ones, it makes it possible, with the help of the developed algorithm, to separate informative frequencies in the spectrum of the analyzed signal, thus making it possible to perform diagnostics when powered by a frequency converter.
