| Abstract: | Based on the theory of DC de-excitation, the condition and factors influencing the generator de-exciation are analysed. Combining with the reformation example of Huaze Power Plant,the de-excitation modes after accident shutdown,normal shutdown and abnormality protection action are proposed to be improved. |
