State evaluation system and method for transformer substation secondary equipment on the basis of equipment patrol inspection information

Abstract

The invention relates to a state evaluation system and method for transformer substation secondary equipment on the basis of equipment patrol inspection information. The system comprises a plurality of monitoring modules, an analysis module and an evaluation module, wherein the plurality of monitoring modules are used for correspondingly monitoring the operation states of the secondary equipment;the analysis module is used for integrating and analyzing the monitored operation states; and the evaluation module evaluates the operation state of the secondary equipment on the basis of analysis results. By use of the state evaluation system and method for the transformer substation secondary equipment on the basis of the equipment patrol inspection information, the monitoring of the self-inspection warning, the information calling, the action behavior and the communication state of the secondary equipment is integrated to comprehensively evaluate the operation state of the secondary equipment in real time, the efficiency of operation inspection work is improved, and an important guarantee is provided for the state overhauling of the secondary equipment.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to the field of substation technology, and specifically refers to a system and method for evaluating the status of secondary equipment in a substation based on equipment inspection information. Background technique [0002] The status of secondary equipment is the basis for ensuring the safety and economic operation of the power grid and carrying out condition-based maintenance, and it is also an effective way to formulate equipment maintenance strategies that suit the actual situation; its core is to fully mine the status inspection data of secondary equipment, and use the inspection data as a judgment It is an effective means of evaluating the status of secondary equipment, thereby improving the operational reliability of secondary equipment in the power system, and finally achieving the goal of safe and economical operation of the power grid. It can not only save a lot of equi...

Problems solved by technology

[0003] At present, the evaluation of the state of secondary equipment is mainly through the evaluation of the health status of the secondary equipment before it is put into operation, the statistics of the defects and abnormalities of the equipment over the years, the status of equipment maintenance, and the running time of the equipment. Scientific and effective monitoring of the status of equipment cannot obtain instant and accurate equipment status, coupled with the lack of information and historical data, resulting in insufficient objectivity and practicability, and subsequent maintenance work cannot be carried out, wasting a lot of equipment maintenance costs and resources, affecting the progress of secondary equipment operation and maintenance

[0004] The research on the state evaluation of secondary equipment in our country is still in the stage of exploration and experimentation, and there is no effective monitoring of the state of secondary equipment. Therefore, the method described in this application is closely combined with a new solution for monitoring the state of secondary equipment in substations. The purpose of the solution is to monitor the real-time operation status of secondary equipment in substations by analyzing the abnormal messages transmitted in the background, thereby improving the efficiency of operation and inspection, and providing an important guarantee for the implementation of condition-based maintenance
