Risk assessment method of power infrastructure based on big data

Abstract

The invention provides a risk assessment method of electric power infrastructure facilities based on big data, comprising the following steps: S1. collecting state parameters of electric power infrastructure facilities, wherein, the state parameters include operating environment parameters and operating physical parameters; S2, obtaining the attribute parameters of the staff performing operation and maintenance on the electric power infrastructure facilities; S3, calculating reliability indexes according to the state parameters of the electric motor infrastructure facilities and the staff attribute parameters; S4, comparing the calculated reliability index with the set reliability index to obtain the difference of the reliability index; 5, comparing the difference value of the reliabilityindex with the set reliability difference value level list, and obtaining the reliability level of the current electric power infrastructure facilities; in the risk assessment, the operating environment of the power infrastructure facilities, their own operating attributes and the attributes of the operation and maintenance staff are considered comprehensively, so that the comprehensive evaluationindicators can be accurately obtained and the accuracy of the final risk assessment can be effectively guaranteed.

Description

technical field [0001] The invention relates to an electric power evaluation method, in particular to a big data-based electric power infrastructure risk evaluation method. Background technique [0002] There are many infrastructure facilities in the power system, such as transformers, circuit breakers, overhead lines, insulators, etc. These devices are one of the power infrastructure facilities, and the operation reliability of power infrastructure facilities is related to the stability of the entire power system. Therefore, how to accurately assess the risk of power infrastructure facilities is related to the stable operation of the entire power grid. In the existing methods, the risk assessment of power infrastructure facilities is often not comprehensive, only by detecting the operating parameters and environmental parameters of power infrastructure facilities. , However, this method ignores the influence of operators in the operation and maintenance process. Different w...

[0002] There are many infrastructure facilities in the power system, such as transformers, circuit breakers, overhead lines, insulators, etc. These devices are one of the power infrastructure facilities, and the operation reliability of power infrastructure facilities is related to the stability of the entire power system. Therefore, how to accurately assess the risk of power infrastructure facilities is related to the stable operation of the entire power grid. In the existing methods, the risk assessment of power infrastructure facilities is often not comprehensive, only by detecting the operating parameters and environmental parameters of power infrastructure facilities. , However, this method ignores the influence of operators in the operation and maintenance process. Different workers have a crucial influence on the power infrastructure facilities in the operation and maintenance process. Therefore, the use of existing methods will lead to power infrastructure facilities Inaccuracies in risk assessment
