Information × Registration Number 0221U101874, 0117U003811 , R & D reports Title Mathematical design of the modes of operations of the system of electric engines of main circulation pumps of nuclear reactor of water-moderated power-reactor-1000 the nuclear power electric stations. popup.stage_title Head Vasyliv Karl M., Доктор технічних наук Registration Date 26-01-2021 Organization Lviv Polytechnic National University popup.description2 The mathematical model and the corresponding software complex which allows to calculate a course of electromagnetic and electromechanical processes occurring in the electrical complex induction motors (IM) of the main circulating pumps (MCP) taking into account operational switches in its power circuit are developed. The power circuit of the electrical complex IM MCP includes a turbogenerator, two transformers of own needs and four IM, which allows with sufficient adequacy for the practice of operation to analyze the modes of operation of the main electrical equipment of the NPP. With the help of software developed on the basis of a mathematical model, a study of the modes of operation of IM MCP reactor WWER-1000 to study the patterns of dynamic electromagnetic and electromechanical processes during start-up, shutdown and power loss of IM. The outflow of IM in quantitative equivalent is established, which is critically important in case of necessity of transition to natural circulation of coolant of the reactor zone.
