Cable tunnel comprehensive state evaluation method based on operation and maintenance system

Abstract

The invention discloses a cable tunnel comprehensive state evaluation method based on an operation and maintenance system. The method comprises the following steps of dividing cable tunnel operation state evaluation factors into quantitative evaluation factors and qualitative evaluation factors; evaluating the operation state of the cable tunnel based on the quantitative evaluation factor and thequalitative evaluation factor; by dynamic weight adjustment method based on a perceptron. through real data training, dividing into dynamic matching quantitative evaluation factor weight and qualitative evaluation factor weight, solving a cable tunnel comprehensive state evaluation result on the basis of a cable tunnel comprehensive state qualitative factor evaluation result, a cable tunnel comprehensive state quantitative factor evaluation result and a quantitative and qualitative evaluation factor weight matrix. Monitoring acquisition data (quantitative evaluation factors) and operation andmaintenance data (qualitative evaluation factors) are combined, and state holographic perception and full-life management of the cable tunnel are achieved.

Description

Technical field [0001] The invention relates to active fault identification and comprehensive state evaluation of power equipment, and in particular to a method for comprehensive state evaluation of a cable tunnel based on an operation and maintenance system. Background technique [0002] The average buried depth of the cable tunnel is large, and the planned maintenance and regular inspections cannot completely solve the operation and maintenance problems. It is necessary to use modern technical means to improve the power cable operation monitoring level to ensure the safe and stable operation of the cable and reduce the pressure on the power cable operation and maintenance of the grassroots unit. [0003] As the operation period of power equipment increases, performance gradually declines, reliability gradually declines, and the failure rate of power equipment gradually increases, which may endanger the safe operation of the system. The operating status of these equipment must be m...

Problems solved by technology

[0005] Although there are relevant state monitoring and evaluation methods for transmission cables at this stage, there is a lack of comprehensive state evaluation methods for cable tunnels, and there are the following deficiencies: monitoring devices and data are not perfect; there is no effective connection between state evaluation factors; The repeated monitoring data from the same source has not been effectively processed and applied; the evaluation items and results of operation and maintenance have not been fully utilized; the monitoring system evaluation and operation and maintenance evaluation have not been effectively coupled, and complementary advantages have not been formed. The evaluation results are in the hands of operation and maintenance personnel The guiding role of the operating status of the cable tunnel is not prominent; the weight distribution is not flexible enough to dynamically divide the application results
