Research On Monitoring And Controlling Of Arc-suppression And Fault Location In Distribution System

As the direct link to customer , the operating reliability of distribution system is very important. This paper studies some important problems on arc-suppression coil,fault line detecting and fault location. The advantage of Resonant Earthed Neutral System(RENS) lies on the performance of arc-suppression coil.. The leading-support & automatic tuning arc-suppression coil aggregates the advantages of traditional coil and electronic technology, which is an orientation of new type coils. In this paper, the new type coil's design gives attention to both extinction of arc and fault line detecting, and the paper brings an improved residual current increment, which is a fault line detecting method and makes the coil obtain better effects on both extinction of arc and fault line detecting. In the end, it studies C-Traveling wave fault location and synthesis various kinds of signal source generator.The paper illuminates and resolves the problems above through theoretic analysis, computer simulation, hardware design,and physical experimentation, which brings an integral solution for adopting RENS, and is full of practicality.
