Research on On-line Monitoring Technology of Running State of Time Synchronization Device Based on IEC61850

Abstract

Smart substation time synchronization is an integral part of the safe and stable operation of substations. Establishing an effective online monitoring technology, the accuracy, stability and status information of the time synchronization information are the focus of substation commissioning, operation and maintenance and overhaul. This paper analyzes in depth the current status, technical route and program implementation of the existing smart grid time synchronization, improves the time synchronization online monitoring technology, and strengthens the monitoring of the excessive operation process of the timing equipment, providing reference for the future time-synchronized online monitoring technology of the smart substation.
