Fault overhauling method and system for secondary equipment of electric power system

Abstract

The invention relates to the field of an electric power system and discloses a fault overhauling method and system for secondary equipment of the electric power system. The method comprises steps as follows: topology monitoring information, operation monitoring information and network communication information of the secondary equipment are acquired; the topology monitoring information, the operation monitoring information and the network communication information are subjected to state monitoring according to a health evaluation model of automation equipment; a state monitoring result is analyzed according to an artificial neural network, and operating states of the automation equipment, a relation between the operating states and a relation between the operating time and the unavailability of the equipment are analyzed; the optimal overhauling time is calculated according to the relation between the operating time and the unavailability of the equipment; a conventional overhauling schedule is optimized and a fault is rapidly positioned according to the relation between the operating states of the automation equipment and the optimal overhauling time. On the basis of the health evaluation model and the state overhauling strategy of the automation equipment, more accurate judgment can be performed, so that the overhauling efficiency is improved, and the fault positioning speed is increased.
