| Abstract: | Effectively combiningthe model of generator, turbine and timing implement together, the electromagnetismtransient model which can simulate generator throwing off load is introduced. Dynamicover-voltage curve of throwing off load of generator with resonant grounding is studied,the influences of several factors are considered, such as the tuning degree of Petersoncoil, dissymmetry extent of generator and the quality factor Q. |
