Modeling of the rotor thermal state of a synchronous turbogenerator of 550 MW with direct cooling of the winding by hydrogen is performed. The temperature field of the rotor is investigated by finite element method in a three-dimensional formulation. Mathematical modeling of the task is implemented...
