Analysis and calculation of stator windings end part temperature field for large synchronous generator

In this paper, the solution region of stator windings end part and the equations of heat conduction are presented. The 3D isoparametic finite element method is used to analyze and compute the temperature field of windward side and leeward side at the stator windings end part, and the influence of different flow speed is discussed. Finally, circulating current is taken into account and some useful conclusions are achieved.
