An Intuitionistic Fuzzy Set Based Synthetical Approach of Faulty Line Selection for Single-Phase Ground Fault
摘要
Abstract
The condition accompanying with single-phase to ground fault occurred in small current neutral grounding system is complex, meanwhile there are many factors influencing the accuracy and reliability of faulty line selection. To utilize fault information more adequately and remedy the defects that fault line selection method based on traditional fuzzy theory cannot express all the fault information, an intuitionistic fuzzy set based synthetical approach of faulty line selection is proposed to improve the success rate of the selection. Firstly, based on the zero-sequence current characteristics of grounding fault, the membership and nonmembership of fault features are determined; then according to the type of grounding fault, the weight coefficient of each method consisting of the synthetical approach of faulty line selection is determined; on this basis, an intuitionistic fuzzy set based synthetical model of faulty line selection is built. A lot of experiments to simulate single-phase to ground fault are performed in a 10 kV high voltage laboratory, and the obtained recorded fault data is processed by program based on Matlab software. The results of faulty line selection show that the proposed method can carry out correct faulty line selection for various types of single-phase to ground fault and the deficiency caused by single fault line selection method can be overcome.关键词
