Abstract

Tools for computer investigation of the modes of operation of induction motors of the main circulating pumps of the VVER-1000 NPP reactor have been created. The mathematical model of the electrical engineering complex «synchronous turbogenerator of NPP unit – electric grid of power system – two transformers of own needs – four induction motors» in phase coordinates, oriented on explicit methods of numerical integration of the system of differential equations is developed. On the basis of the mathematical model the software designed for the study of electromagnetic and electromechanical processes of the system of induction motors of the main circulating pumps of the VVER-1000 nuclear reactor in the modes of: operative switching including start and run, switching to standby power, self-start of the motors with turbogenerator’s run-out and without it is developed. The investigations of the processes in the system of induction motors in the mode of operative switching during their power supply from the turbogenerator are carried out and the basic regularities of their course in qualitative and quantitative relations are established.
