A New Scheme of Line Selection about Earth Fault Diagnosis in NUGS
Hu Zuo · Nanfang dianwang jishu · 2008
The existing line selection criterion for a single-phase fault is not good enough in adaptability,and it is necessary to search a better one.An integrated line selection criterion for earth fault diagnosis in NUGS is proposed in this paper based on Decaying High Frequency Component and Residual Current Method in combining with fussy information fusion,and a concision subordinate function for this selection is constructed.Operation results from a sample selection platform show that the new method has excellent disturbances-proof ability,and is feasible and effective.
