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.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method and system for troubleshooting secondary equipment in a power system. Background technique [0002] For power system primary equipment such as generators, transformers, circuit breakers, isolating switches, etc., its condition-based maintenance includes online monitoring and diagnosis, equipment operation and maintenance, live detection, preventive tests, fault records, equipment management, equipment maintenance and maintenance. Finally, it is necessary to make maintenance decisions based on comprehensive equipment operation information, unit equipment operation status, and power market needs. For power secondary equipment, it refers to the equipment that controls, regulates, protects and monitors primary equipment, including: AC measurement system; DC operation and signal system; logic judgment system; communication system; shielding and grounding system, etc., specificall...
