GIS based multilevel intelligent fault diagnosis system on electric power equipment

Abstract

Along with the application which AM/FM/GIS has been used in distribution network strengthening, at present it has become a technique development direction that SCADA should integrate with AM/FM/GIS. In pace with electrified wire netting scale growing immensely, the equipment requirements are increasing and their function is more and more advanced. It can not satisfy the requirements of a practical system to adopt traditional concentrated and single fault diagnosis methods. We designed a distributed multilevel intelligent fault diagnosis method in this paper. First resolve the equipment fault diagnosis of the whole system into a fault diagnosis of each subsystem, then, according to the characteristic of the equipment type, transfer many sorts of fault diagnosis means from the knowledge-base to carry on cooperation fault diagnosis under the control of multilevel intelligent fault diagnosis tactics. Leave the final diagnosis result with a fault database to offer system-making-policy and alarm information.
