Measurement and control equipment health state evaluating system and method based on online monitored data

Abstract

The invention discloses a measurement and control equipment health state evaluating system and method based on online monitored data, and belongs to the field of electric power system operation and management. The method comprises the steps of: adding some information monitoring functions reflecting the health state of measurement and control equipment to the inner part of the measurement and control equipment, uploading the information monitoring functions to a measurement and control equipment health state evaluating work station, and carrying out real-time monitoring and evaluating on the health state of the measurement and control equipment. According to the method, an online monitored information classification model is established, the health state of the equipment is determined according to line-crossing and alarming conditions of diffident kinds of equipment information, a health state evaluating method is established based on online information, and the health state of the equipment is evaluated. The method provided by the invention is the health state evaluating method based on the online monitored information, the defects of a conventional evaluation model in which evaluation is carried out mainly based on history information and manual evaluation are overcome, and the health state of the measurement and control equipment is more accurately reflected in real time.

Description

technical field [0001] The invention relates to the field of power system operation and management, in particular to a system and method for evaluating the health status of measurement and control equipment based on online monitoring data. Background technique [0002] The condition-based maintenance of measurement and control equipment is a research hotspot at home and abroad. Many scholars at home and abroad have carried out relevant research. As the basis of condition-based maintenance of measurement and control equipment-health assessment, due to the limitations of secondary equipment monitoring technology and the need for recording information The records and management of the equipment are not standardized enough, and the secondary equipment health status assessment technology cannot make breakthrough progress. [0003] Traditional secondary equipment health status assessment models are mostly based on historical operation record information, classify historical operat...

Problems solved by technology

[0004] (1) At present, this evaluation method only evaluates the health status of equipment based on the information of historical operation records, and does not consider the real-time monitoring data that directly reflects its health status. Therefore, the evaluation results are not very accurate

[0005] (2) During the evaluation process, experts determine the weight of various types of information in the evaluation based on actual experience, and the operation and maintenance personnel score item by item according to the operation status of the equipment. Obtained device scoring results, determining the current health status of the device may have a large deviation
