The temperature field of the rotor of the synchronous turbogenerator is investigated. The temperature distributions in rotor windings of 300 and 550-MW turbogenerators with direct hydrogen cooling of rotor winding are obtained. The transition to more power is implemented by increasing the hydrogen p...
