A New Method of DC System Grounding Fault Detection Based on Duffing Oscillator

WANG Hong-tao1,LIU Hui-jun2(1.Ningde Teachers College of Physics and Electrical Engineering,Ningde 352100,China; 2.Baoji Power Supply Bureau,Baoji 721000,China)  
The paper presents a new fault detection method of the Duffing DC system grounding based on the DC system grounding fault principle and the low-frequency injection method in order to make up for inherent defects of the low-frequency injection method and solve the traditional problems of the ground capacitance and harmonic interference on fault detection.In order to determine the system state of the phase transition,the DC component of detection characteristic quantities should be removed by the double Hilbert transform,and a criterion made by lyapunov index,the phase diagram and time domain graph.Grounding resistance can be obtained and the ground slip can be determined according to the amount of fault feature value and phase obtained by the phase change conditions.Advantages are shown such as high stability,high precision,strong anti-interference performance when compared with the wavelet detection method.Simulation results show the effectiveness of the method.
