description: The subject of the graduate qualification work is "Efficiency of the installation of frequency control on the MCP group of the Kola NPP in maneuvering modes". The object of study - the main circulation pumps of the Kola NPP. The subject of research - the frequency regulation of a group of main circulation pumps. The relevance of the subject is due to the economic and ecological problems of modern nuclear installations. The purpose of the work - do research the control systems for the frequency of rotation of the rotors of the electric motors of the main circulation pumps of NPP. Tasks: 1) analyze the working modes of the main circulation pump; 2) select a frequency control device for a group of circulation pumps; 3) study the possibilities of installing frequency regulation; 4) do conclusions about the efficiency of the use of a frequency-regulating drive. Scientific and practical significance - the application of frequency regulation at large energy enterprises. The electrical load in the Murmansk region and at the Kola NPP was studied, measures were proposed to improve the energy efficiency of the main circulation pumps. Using data with the website of JSC Â«System Operator of the Unified Energy SystemÂ», an analysis of electricity consumption by months for 2021 was carried out. Based on the data graphs were built: âElectricity consumption and generation for the reporting month 2021 in the Murmansk regionâ, âElectricity consumption and generation for the reporting month 2021 in the Murmansk region and at the KNPPâ, âTotal consumption in the underloaded block involved in the work at frequency regulation of the load. The selection of a frequency-regulating device for the main circulation pumps of the KNPP was carried out, in comparison between three brands of different manufacturers. The payback period from the installation of frequency control equipment is calculated.
