Reliability determining method and device for electric power communication net

Abstract

The invention discloses a reliability determining method and device for an electric power communication net. The method comprises the steps that reliability indexes of the electric power communication net and the practical values of all the indexes are determined; value ranges of all the indexes at all preset grades are determined; positive ideal solutions and negative ideal solutions of all the grades are calculated according to the value ranges; every two indexes are compared, and weight intervals of all the indexes are calculated according to comparison results; Euclidean distance intervals of the practical values of the indexes to the positive ideal solutions of all the grades and Euclidean distance intervals of the practical values of the indexes to the negative ideal solutions of all the grades are calculated according to the weight intervals; the degrees of association of the practical values of the indexes and all the grades are calculated according to the Euclidean distance intervals; the grade corresponding to the maximum value of the degree of association is determined as the reliability grade of the electric power communication net. Objective influences can be weakened by calculating the weight intervals; the indexes are graded, the Euclidean distances are normalized through weighting, the similarity degree of the overall indexes and all the grades can be reflected, and the reliability of the electric power communication net can be integrally and comprehensively evaluated.

Description

technical field [0001] The invention relates to the technical field of electric power communication networks, in particular to a method and device for determining the reliability of electric power communication networks. Background technique [0002] The electric power communication network has been built into a power-specific optical fiber network covering the main areas of the country and a power-specific digital program-controlled switch network covering the power supply departments of cities above the county level across the country, and has realized nationwide networking and full-time automatic dialing. The power communication system provides dispatching communication, administrative office telephone, relay protection information transmission, automation information transmission, network monitoring information communication, computer network communication, conference call, video conferencing, distribution network automation information transmission, and electric energy m...
