Abstract

The invention provides a power distribution network equipment reliability analysis method based on multi-system information fusion, and the method comprises the steps: receiving the operation data, collected by a sensor and monitoring equipment arranged on a preset section monitoring station and a maintainer, of all pieces of power distribution equipment, and receiving the self-checking data during the fault self-checking of all pieces of power distribution equipment; performing dynamic data and power utilization peak analysis on each power distribution equipment according to the operation data of each power distribution equipment and the corresponding self-inspection data so as to establish a life curve graph of each power distribution equipment, and determining a life value of each power distribution equipment within a predetermined time range according to the life curve graph of each power distribution equipment; and comparing the service life value of each power distribution equipment with a preset threshold value, and further analyzing the reliability of each power distribution equipment according to a comparison result. By implementing the method, the comprehensive service life of the equipment can be comprehensively evaluated for analyzing the reliability of the power distribution network equipment, and the analysis error can be reduced.

Description

technical field [0001] The invention relates to the technical field of distribution network equipment analysis, in particular to a distribution network equipment reliability analysis method and system based on multi-system information fusion. Background technique [0002] The distribution network is composed of overhead lines, cables, towers, distribution transformers, isolating switches, reactive power compensators and some auxiliary facilities, and plays an important role in distributing electric energy in the power network. [0003] At present, the reliability analysis of the distribution network only relies on the parameters of the equipment, but there are large errors, and it is impossible to fully evaluate the comprehensive life of the equipment. Therefore, it is necessary to propose a new reliability analysis method for distribution network equipment, which can comprehensively evaluate the comprehensive life of equipment, use it to analyze the reliability of distribut...
