Abstract :
This paper presents two-dimensional field-circuit model of 500 MVA turbogenerator. Model is designed to calculate static and dynamic characteristics of machine. During solving field equations real physical characteristics of materials, configuration of windings, damper circuit and motion elements in electromagnetic field are taken into account. In circuit part there is an electrical scheme. The electrical elements correspond with winding in the field model. Parameters of frontal connections are included. The model was applied to calculate stator currents, magnetic torque and rotor speed in case of sudden power increase.
