Paper Abstract

It's a new idea for using zero-sequence optical current transducer (ZOCT) to solve the measure problem of single-phase-to-ground fault section determination in distribution system. However the outputs of ZOCT are weak and mixed with noises, decreasing the detection sensitivity. Chaotic oscillator system is sensitive to certain signal and immune to noise, so the signal detection based on Duffing oscillator can improve the detection sensitivity and anti-interference capability. In this paper, combining Duffing oscillator with ZOCT, a new scheme of fault section determination is presented, with good sensitivity and reliability. The results of simulation and experiments proved this method is effective and feasible.
