Fuzzy decision making applied to high impedance fault detection incompensated neutral grounded MV distribution systems

摘要

The detection algorithms depend on the network topology, thenneutral grounding of the secondary winding in HV/MV transformers beingnone of the main factors to consider. In compensated distributionnsystems, we need complex detection algorithms based on networknparameters estimation. In this paper we present fuzzy decision makingntechniques as an option to improve the new DSTRP high impedance faultndetection algorithm behaviour
