Abstract

The invention relates to the technical field of state evaluation of power system equipment, and especially relates to a power transmission and transformation equipment evaluation model and a processing method based on big data. Aiming at the problem that the comprehensive evaluation on the state of the power transmission and transformation equipment is insufficient in the prior art, the invention provides the power transmission and transformation equipment evaluation model and the processing method based on the big data, so that the abnormal states of various power transmission and transformation equipment can be quickly detected. According to the power transmission and transformation equipment evaluation model and the processing method based on the big data provided by the invention, by constructing system proposition sets and evidence bodies, calculating reliability intervals under an independent action and a combined action of each evidence body, and constructing a corresponding decision rule according to specific problems, the evaluation model of each equipment can be obtained, a decision conclusion can be obtained according to the decision rule, so that the comprehensive differentiation evaluation on different power transmission and transformation equipment can be realized.

Description

technical field [0001] The invention relates to the technical field of power system equipment status evaluation, in particular to a big data-based power transmission and transformation equipment evaluation model and processing method. Background technique [0002] The existing state evaluation methods for power transmission and transformation equipment are mainly aimed at equipment groups, ignoring individual attributes such as operating conditions and manufacturing processes, and have low pertinence and accuracy. Developing differentiated state evaluation technology for power transmission and transformation equipment based on big data analysis, focusing on mining the coupling relationship between equipment state information, establishing a differentiated state evaluation model and developing rapid evaluation methods are the development directions in the field of power system equipment state evaluation. [0003] With the rapid development of computer network technology and t...
