  • This paper presents a stator ground protection scheme based on the fault current flowing in the breakdown channel. It trips only if the fault current exceeds the fault current tolerance capacity of the generator. Otherwise, it will just emit alarm signals. Thereby, the unnecessary trip-out of large generator can be avoided. The stability of the power system and the generator security can then be ensured. To achieve the scheme, methods of calculating the fault current in real time are proposed… CONTINUE READING
