AI-based methods in practical fault location of medium voltage distribution feeders

The fault location expert system is an application of a distribution management system, which is a part of the integrated control center environment composed of different computer systems and distribution automation. The expert system applies AI-based methods (e.g., object-oriented modeling, blackboard technique, fuzzy reasoning, decision tree) in incorporating data on external systems in order to support the control center operator in network operation. At present the expert system is in everyday use in several distribution utilities.
