Abstract

The invention discloses a quantitative risk evaluation method for power equipment based on state evaluation. The method comprises that according to statistic data of power equipment, risks of potential faults of different parts in the power equipment are identified by utilizing an influence analysis method; the fault probability of equipment when the risk occurs is predicted, and the health degree of the equipment is obtained via reference state analysis; a relation model between the fault probability and the healthy degree of the equipment is established, and a risk consequence of potential faults of the parts of the power equipment is analyzed; the influential degree of each part on the equipment function is determined; according to the equipment fault probability and risk consequence, a risk value of the potential fault of each part of the power equipment is calculated; and a risk grading model is established, and according to the risk values, risk grades of the potential faults of the parts of the power equipment are determined. According to technical schemes of the invention, accurate technical basis is provide for operation and maintenance of the power equipment.

Description

technical field [0001] The invention relates to the technical field of grid electric power, in particular to a state evaluation-based quantitative risk assessment method for electric equipment. Background technique [0002] With the advancement of electronic power technology, the power grid is developing in the direction of intelligence, long-distance, and UHV. In order to achieve multi-objective comprehensive optimal technical solutions such as cost, quality and benefit, it is necessary to evaluate the probability and risk of different faults that may exist in power equipment according to the operating status of the equipment, and adopt targeted maintenance methods to further improve the quality of power equipment operation and maintenance. The key role or purpose of risk assessment for electrical equipment is to provide a scientific basis for formulating preventive measures and maintenance decisions. [0003] The core technical issues of equipment risk assessment include:...
