Multi-Timescale-Based Fault Section Location in Distribution Networks

To meet the requirements of quickness and accuracy for fault location in smart distribution networks with high penetration of distributed generations, we propose an integrated fault section location method based on multiple timescales. On the millisecond timescale, we present a distributed fault sec...
