Abstract：In order to accurately analysis the dynamic problem of the interaction between the generator and power network under the condition of the disturbance and the faults in the whole system,a field-circuit-network coupled time-stepping finite element model containing excitation system and speed control system was presented.Not only the nonlinear feature,including the magnetic saturation,distortion of electromagnetic field and eddy current were considered,but also the dynamic change of speed and parameters of transformer and power transmission system were considered.The implement measures of excitation system and speed control system were given.To verify the model,Take a 1407MVA turbo-generator as an example,the transient process of the open phase fault was simulated.This transient process was simulated when the generator is running under rated operating condition which connects with power network,and the A phase breaker of transformer secondary side (high voltage side) was suddenly turned off.Compared with the result of traditional Park equation,the field-circuit-network coupled time-stepping finite element model is verified.
