This paper presents two-dimensional field-circuit model of turbo-generator 500 MVA. Model is designed to calculate static and dynamic characteristics of machine. The model was applied to calculate damper winding currents for the sudden short circuit. Currents distribution and flux lines for the sudden short circuit was calculated too. Using the model of turbo-generator it is possible to calculate flux and current densities, field distributions and other physical quantity for every time step of the simulation.
