Abstract
The small current grounding system is briefly introduced.The neutral point ungrounded system in small current grounding system was set as an example,and the single-phase earth fault was analyzed.The theory and the basic algorithm for support vector machine (SVM) are elaborated in detail; a meaningful attempt was made to apply SVM algorithm ; SVM model was established for single-phase grounding fault of the neutral point ungrounded system.The simulation results of fault line selection show that this feasible method ensures higher accuracy of line selection.
