Fault analysis expert system for power system

Internet not only brings opportunities to power utilities, but also takes challenges. By virtue of internet and data warehouse, we developed support software which collected and stored data from devices in substations such as relay protect devices, dynamic process recorder and so on. Based on intelligent agent theory, knowledge discovery theory & rough set theory, we developed a distributed intelligent system (Fault Analysis Expert System based on Intelligent Agent), which can analyze reasons that cause any failures. In the system, intelligent agent is the distributed intelligent unit providing services for other units; knowledge discovery theory based on rough set theory can acquire and optimize rules from fact information.
