| Abstract: | Error acting of excitation loss protection during generator leading phase testing is introduced. This thesis anaIyzed and compared different impedance circle constant values adopted by generator loss of excitation protection with corresponding limiting cases of genetator leading phase depth. It is put forward a method by using generator low excitation limit curve to prevent generator loss of excitation protection caused by genetator leading phase misoperation. |

| Keywords: | generator leading phase loss - of - field protection limit of low excitation |
