Design and Implementation of Time Signal Closed-loop Monitoring of Time Synchronization System in Intelligent Substation

Abstract

This paper analyzes on-line monitoring technology of intelligent substation time synchronization system and judgment method of synchronous abnormality, abnormal problems in the timing section of the time synchronization system, a method for closed-loop monitoring of time synchronization systems is proposed, by detecting the signal of the timing output interface. Perform failure analysis and send result data, improves the time synchronization status monitoring requirements at the station.
