Summary

Indicators of damage to turbogenerators of power plants of NPP of Ukraine for 2006-2010 and availability of turbogenerators of type of TVV-1000-2 of power plants of NPP of Ukraine in 2003-2010 presented in this paper. The necessity of identifying areas of local overheating in the knots and elements of the turbogenerator.Тechniques, algorithms and the program is developed for run on a computer calculation of three-dimensional temperature field together core and windings of stator of turbogenerator type TVV-1000-2Y3 for the determination of local overheating. Numerous computational experiments are conducted on determination of local overheats in the windings and core of stator of turbogenerator at presence of thermal defects. Developed recommendation on the increase of safety, reliability and efficiency of exploitation of turbogenerators of type TVV-1000-2 of NPP.

Keywords: turbogenerator, windings, core of stator, bar, thermal defects, overheating, localization.
