AN APPROACH TO FAULT DIAGNOSIS OF SUBSTATION BASED ON ROUGH SET AND NEURON NET WITH SWITCH FUNCTION

An approach to fault diagnosis of substation based on rough set and neuron net switch function is presented. In this method the rough set is adopted to mine hierarchically diagnosis knowledge of substation based on switch information of breakers and relays because of its ability to dispose uncertainty information. Then the diagnosis is implemented through multi-layer neuron net with switch function. It is an effective method online for fault diagnosis of substation.
