Traveling Wave and Wavelet Based Fault Location Detection in Microgrids

Abstract

Demand for renewable energy sources is increasing day by day. With the increase in demand for renewable energy sources, the use of microgrids also increases. Microgrids, compared to traditional grids, have a more complex structure and need more complex protection functions. In this study, a traveling wave-based fault location detection system for microgrids with loop distribution systems (looped microgrids) was developed. In traveling wave-based fault location, measurements taken from one or both ends of a line are used. However, in looped grids, lines do not have a beginning or an end. In order to allow the use of traveling wave-based protection in loop distribution systems, the system is separated into three zones. To each three separate zone a type D fault locator method was applied, and by ensuring that these algorithms worked in accordance, fault location detection was carried out in a looped microgrid.
