Knowledge based alarm handling and fault location in distribution networks

A knowledge-based system for fault analysis in the area of medium-voltage distribution networks is described. It is based on an expert system shell developed for applications in the field of power supply. Applications like contingency analysis or corrective switching have been realized. The solution for fault analysis attaches great importance to portability, simple integration in different telemetry and control systems, integration of different protection relay types, and capability of working with little information about the electrical network and the triggering of the protection devices
