Abstract :
The calculation of large hydrogenerator´s magnetic and thermal fields is very complicated due to the complexity of their construction, different properties of their materials and nonlinearity of core B-H curve. Finite Element analysis tools are relatively convenient for solving these problems. In this paper, Ansys software is adopted in analysis of the Three Gorges´ 840MVA evaporative cooling hydrogenerator. Magnetic analysis and thermal analysis are made respectively. By doing that we got satisfying results and the results also show the advantage of the evaporative cooling technology.
