| Abstract: | Asynchronous operation at excitation loss of turbine generator is a special operating mode. Numerical computation of three dimensional eddy current field of rotor at this operation mode is useful for operation and design of turbine generator. That operating mode was discussed. The method used for computing three dimensional electromagnetic field was given. Also the method transferred the result of electromagnetic computation to the frequency parameter was given. A simplified model was used for verifying reliability of those methods. |
