Grid‐wide area protection settings analysis using protection settings evaluation tool

Abstract

This study sets out requirements for a tool to automatically evaluate protection relay coordination and assess, track, and visualise protection coordination results for large grid areas. The tool requirements include the selection process for which fault types, fault locations, contingencies, and generation dispatch should be studied, how the relay performance could be assessed, and how the large datasets produced by such analysis could be stored and visualised. Using these requirements, add-on tools were developed for two popular commercial short-circuit analysis programmes and tested and validated using network models from a number of real transmission and distribution grids.
