Method and device for maintaining power transmission and transformation equipment

Abstract

The invention provides a method and device for maintaining power transmission and transformation equipment. The method comprises the following steps of: acquiring data required by equipment maintenance decisions, such as equipment state quantity index warning information data acquired from a monitoring warning layer, state evaluation result data acquired from a state evaluation layer, fault diagnosis result data acquired from a fault diagnosis layer, risk evaluation result data acquired from a risk evaluation layer, maintenance decision suggestion data generated by a maintenance policy layer and external constraint conditions; and carrying out decision analysis on the acquired data, establishing an equipment state maintenance policy model, optimizing maintenance sequence, maintenance time and maintenance grade of the power transmission and transformation equipment, and determining equipment maintenance property as well as arranging a maintenance decision plan. By using the method and device, key equipment faults and unnecessary maintenance operations can be avoided by timely maintenances, and the optimal distribution and use are searched in limited maintenance cost, thus effectively saving manpower and material resources.

Description

technical field [0001] The invention relates to the field of power systems, in particular to a method for overhauling power transmission and transformation equipment and a device for overhauling power transmission and transformation equipment. Background technique [0002] With the rapid expansion of the scale of the power grid, the number of power transmission and transformation equipment has increased sharply, and the impact of power transmission and transformation equipment failure on people's production and life is increasing. People's requirements for reliable power supply of the power grid are getting higher and higher. Therefore, in order to reduce unnecessary repeated power outages, reduce the number of equipment outages, improve equipment availability, and ensure safe and stable operation of the power grid, maintenance of power transmission and transformation equipment is inevitable. [0003] The traditional maintenance mode of power transmission and transformation ...

AI Technical Summary

Problems solved by technology

[0003] The traditional maintenance mode of power transmission and transformation equipment includes two methods: after-the-fact maintenance and regular maintenance. Among them, the after-event maintenance is a passive maintenance, which is prone to unforeseen equipment damage and causes certain losses; while the regular maintenance mode is poorly targeted. The high test rate of health equipment makes the contradiction between the number of overhauled equipment and limited manpower and material resources more prominent, which can no longer meet the actual needs of production

It can be seen that the current maintenance management mode has great constraints on the grid power supply
