Abstract

This paper presents the numerical simulation of flow-thermal coupling for 2 MW Doubly-Fed Induction Wind Generator (DFIG). With fundamental assumptions and corresponding boundary conditions, the number of grid is reduced to save calculation time. The temperature of internal air for different cooling system configuration is calculated with commercial FEA software FLUENT without assumption. Four cooling system configurations of DFIG are presented, analyzed and compared in details. The best cooling system configuration of DFIG has been found and will be used into our DFIG production.
