摘要：

In order to research the losses and heat of damper bars thoroughly, a 3D moving electromagnetic field FE model of tubular hydro-generator and a 3D temperature field FE model of the rotor are built respectively. Furthermore, according to the different operating conditions, the compositive calculations about the losses and temperatures of the damper bars of a 36MW tubular hydro-generator are carried out, and the data are compared with the test. The results show that the computation precision is satisfied.
