The objective is to develop an integrated software system with a unified user interface for comprehensive processing and analysis of fault events in distribution systems. The system will include newly developed functions using fault event records for unintentional islanding detection, fault current estimation and statistical analysis of fault events using artificial intelligence tools. The fault localization (Vdip2) and fault event analysis (FRA) modules, developed under the previously supported projects TK04020187 and TK04020230, respectively, will be optionally integrated into the developed system and will be duly licensed for this use and complemented with a framework extending their application possibilities in accordance with the requirements of the DSOs.
