Problems solved by technology

[0004] The current risk assessment analysis of power transmission and transformation equipment focuses on equipment assets, the degree of asset loss, and the probability of equipment failure. Although the risk assessment results are valuable, it is difficult for maintenance personnel to judge the current status and status of power transmission and transformation equipment. Determine the appropriate maintenance strategy

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0034] refer to figure 1 , figure 1 A method for optimizing the maintenance strategy by risk assessment of power transmission and transformation equipment provided by the present invention mainly includes the following steps:

[0035] Step 1: Collect information sources required for risk assessment, including: fault tree structure, expert experience, information on the entire process of equipment (including design, manufacture, and operation) and fault diagnosis conclusions.

[0036] Fault tree structure: A tree view structure that describes the evolution process of equipment faults and is established based on the basic principles of fault trees after statistical analysis of various failure modes and causes that occur during the life of the equipment.

[0037] Expert experience: Obtain relevant parameters that are difficult to collect and col...

Abstract

The invention relates to the technical field of assessment, diagnosis and reliability of power transmission and transformation equipment, and particularly relates to a method for optimizing a maintenance strategy by using risk assessment of power transmission and transformation equipment. According to the invention, information sources required by risk assessment such as a fault tree structure, specialist experience, equipment whole process information and fault diagnosis are collected, the fault criticality and a criticality index are acquired through analyzing on the basis of the information sources, the risk level of the equipment is judged in a risk matrix, risk ranking is carried out according to the risk level, and a corresponding maintenance strategy is formulated.

Description

technical field [0001] The invention belongs to the technical field of evaluation, diagnosis and reliability of power transmission and transformation equipment, and in particular relates to a method for optimizing maintenance strategies by utilizing risk assessment of power transmission and transformation equipment. Background technique [0002] Risk assessment refers to the analysis and evaluation of the inherent or potential hazards and their severity in a working system with specific functions, and makes a quantitative expression with a predetermined index, level or probability, and finally evaluates the risk according to the magnitude of the quantitative value. Determine the preventive or protective countermeasures that need to be taken to achieve the purpose of effectively reducing risks. [0003] With the development of society and economy, the demand for electricity continues to expand, the number of power grid assets continues to increase, the investment in new subst...
