Diagnosis method for pre-channel fault of power distribution automation system

Abstract

The invention discloses a diagnosis method for a pre-channel fault of a power distribution automation system. The method comprises the steps of allowing a power distribution automation master station system to monitor an operation state of a power distribution terminal, allowing a communication network management platform to monitor a state of an intermediate link communication equipment, combining communication network management data and the operation state of the power distribution terminal, performing real-time monitoring and management on the power distribution terminal, communication access network equipment, an optical cable and a communication channel resource within the jurisdiction of the power distribution automation system, performing fault analysis and positioning on a communication abnormity state of the power distribution terminal, and issuing a communication abnormity report of the power distribution terminal. The method can find a cause of the pre-channel fault more comprehensively, achieves accurate positioning of a fault node, significantly improves the defect elimination management efficiency of operation and maintenance personnel for the power distribution terminal and communication, and further ensures stable operation of a power distribution network.

Description

technical field [0001] The invention relates to a fault diagnosis method, in particular to a fault diagnosis method for a front channel of a power distribution automation system, and belongs to the technical field of power supply and distribution.
