Calculation on Thermal Field of a Doubly-Fed Induction Generator with Axial-Radial Ventilation Cooling System
A type of doubly-fed induction generator with air-water cooling and axial-radial ventilation cooling system is proposed in this paper. A half-axial segment stator-rotor coupled thermal field 3D model of the doubly-fed induction generator prototype is built with some properly assumptions, according to its symmetry in electromagnetic structure and cooling system. Stator-rotor coupled thermal field distribution of prototype is calculated under rated operating. The influence of water mass-flow and number of cooling-ribs to the thermal field distribution is also studied with the 3D model.
