Problems solved by technology

Although the current power grid has formed a systematic and standardized model in the risk assessment of power operations, due to the impact of other external factors on the safety of power operations, including the working environment, working conditions and personnel inspections of power operations, the traditional risk assessment of power operations Personnel determine the risk level of electrical work based on their own experience only based on the characteristics of the work itself, and the subjective factors are relatively large

Embodiment

[0061] Please refer to figure 1 , figure 1 It is a flow chart of a power operation risk assessment method suitable for variable weight fuzzy comprehensive assessment.

[0062] like figure 1 As shown, the operation steps of a power operation risk assessment method suitable for variable weight fuzzy comprehensive assessment are as follows:

[0063] S101: Define electric power operation risk assessment indicators that can measure the degree of electric power operation risk, set the set as U;

[0064] The risk assessment index for measuring the risk degree of electric power operation can be defined from multiple angles according to the actual electric power operation situation;

[0065] The described electric power operation risk assessment index is stratified according to the target layer, the standard layer, and the program layer; then the elements in the criterion layer and the program layer are compared in pairs, and according to "Santy's 1-9 scale "Method" to determine th...

Abstract

The invention discloses an electric power operation risk assessment method suitable for variable weight fuzzy comprehensive assessment. The method comprises the steps of obtaining an electric power operation risk assessment index capable of measuring an electric power operation risk degree; layering the power operation risk assessment indexes by using an analytic hierarchy process, and determiningweight initial values of the power operation risk assessment indexes between the layers relative to the power operation risk assessment indexes of the previous layer; obtaining score values of the electric power operation risk assessment indexes before each electric power operation, and redistributing the weight initial values according to the score values to obtain redistributed weight values; determining an evaluation set and a membership calculation function of the evaluation object; enabling the membership calculation function to perform multi-level fuzzy comprehensive evaluation on the evaluation set to obtain a fuzzy comprehensive evaluation result; and determining the corresponding power operation risk assessment level from the vector of the fuzzy comprehensive assessment result according to the principle of redistributing the weight and the membership degree maximum. According to the embodiment of the invention, risk levels can be objectively assessed in multiple aspects for operation risks.

Description

technical field [0001] The invention relates to the field of electric power operation risk assessment, in particular to an electric power operation risk assessment method suitable for variable weight fuzzy comprehensive assessment. Background technique [0002] In recent years, with the increasing scale of the power grid, there are more and more problems in the safety of power operations, accompanied by accidents in the process of power operations. Although the current power grid has formed a systematic and standardized model in the risk assessment of power operations, due to the impact of other external factors on the safety of power operations, including the working environment, working conditions and personnel inspections of power operations, the traditional risk assessment of power operations Personnel only determine the risk level of electric power operations based on their own experience, and the subjective factors are relatively large.
