Increasing the reliability and efficiency of operation of turbine generators of power stations
An analysis of existing methods and means of reducing the heating of the final part of the stator core of powerful gas-cooled turbogenerators was carried out. The main shortcomings of these methods and tools have been revealed. Various design factors that affect the distribution of the magnetic field and temperature in the end zone of a powerful electric machine are analyzed. On the basis of a complex study of electromagnetic and thermal processes with the help of mathematical and physical modeling, a new constructive solution of the stator core of an alternating current electric machine was developed and scientifically substantiated, which allows reducing the maximum temperature and reducing the radial unevenness of the heating of the extreme packages of the core. For students, postgraduates, engineers and researchers of relevant specialties.
