Problems solved by technology

[0002] At present, the evaluation of power grid equipment is mostly based on the evaluation of equipment operation information. The evaluation results can only reflect the operation information of the equipment unilaterally, and cannot meet the health status evaluation of the entire life cycle of the equipment.
In the power grid system, the importance of various equipment is different, and the impact of its failure on the power grid is also different. This requires that the evaluation of equipment operation status cannot only judge the operation health status of equipment based on unilaterally reflected operation information, which is not conducive to To maximize the utilization of power grid assets, it is impossible to judge the health status of equipment in advance, resulting in a large workload of maintenance personnel and a large loss of power grid resources

Abstract

The present invention relates to a power grid physical asset evaluation method based on an analytic hierarchy process, belonging to the technical field of power grid device evaluation. The method is performed based on asset register information and operation information of a device to be evaluated, and comprises the steps of: selecting technical indexes which can reflect the operation level of thedevice most, constructing a technical index system reflecting the operation state of the device, employing the analytic hierarchy process to calculate the weight of each index, obtaining the score proportion of the device to be evaluated, employing the least squares fit to obtain each index evaluation curve by means of the asset register information and the operation information, and finally obtaining the operation health state information of the device in a life cycle. The method grasps the operation level of the power grid physical asset at the datamation angle so as to improve the power grid asset management level, guides the management method of the power grid asset through an evaluation result to improve the management efficiency, achieve the maximization utilization of the power grid asset, save the human cost and have a good guidance meaning of reasonable distribution of the power grid resources.

Description

technical field [0001] The invention belongs to the technical field of power grid equipment evaluation, and in particular relates to a power grid physical asset evaluation method based on analytic hierarchy process. Background technique [0002] At present, the evaluation of power grid equipment is mostly based on the evaluation of equipment operation information. The evaluation results can only reflect the operation information of the equipment unilaterally, and cannot meet the health status evaluation of the entire life cycle of the equipment. In the power grid system, the importance of various equipment is different, and the impact of its failure on the power grid is also different. This requires that the evaluation of equipment operation status cannot only judge the operation health status of equipment based on unilaterally reflected operation information, which is not conducive to To maximize the utilization of power grid assets, it is impossible to judge the health sta...
