Method for assessing state of multi-dimensional power transmission equipment

Abstract

The invention provides a method for assessing the state of multi-dimensional power transmission equipment. The method includes the steps that firstly, a power transmission equipment state assessment model of a multi-layer structure is established and a special assessment period and a special line section are established; then, an accumulative mark reducing method serves as a basic marking method for all parameters in the assessment model, and in combination with the assessment period and an assessment section, actual weights and actual mark reducing values of all the parameters are given out; finally, according to parameter marks, the marks of all components, a tower section and the whole of the power transmission equipment are sequentially calculated, and the overall state of the power transmission equipment is comprehensively assessed in combination with the two dimensions of the assessment period and the assessment section. By the adoption of the method, information of three dimensions of line mark acquisition, time and space is fused, the method for assessing the state is comprehensive and expandable, and a final multi-dimensional assessment result is close to the true operation state of the power transmission equipment.

Description

technical field [0001] The invention relates to a method for evaluating the status of multi-dimensional power transmission equipment. Background technique [0002] The safety of power transmission equipment is the basis for safe, reliable and stable operation of the power grid. Effective and accurate assessment, diagnosis and prediction of equipment status will not only directly affect subsequent risk assessment and maintenance decisions, but also improve power supply reliability and power grid operation. An important way to the level of intelligence. [0003] Due to the wide distribution area of ​​power transmission equipment, numerous sub-components, and the large impact of natural environment, the state evaluation of power transmission equipment faces the difficulty of comprehensiveness and accuracy. To conduct a comprehensive and accurate state assessment, it is necessary to integrate multi-source heterogeneous information such as equipment state information, power gr...

Problems solved by technology

At present, the cumulative deduction method is used as the primary evaluation method in the transmission equipment evaluation guidelines, industry standards and other relevant normative documents of the State Grid and China Southern Power Grid. The classification is more fine-grained, which is convenient for digital management, but the standard does not consider the absolute, the ambiguity and uncertainty of the state quantity
