GPS and IEEE 1588 synchronization for the measurement of synchrophasors in electric power systems (original) (raw)

This research investigates the synchronization requirements for Intelligent Electronic Devices (IEDs) within electric power systems, particularly focusing on the impact of Distributed Generation (DG) on measurement accuracy and quality assessment. It evaluates both GPS-based synchronization for microsecond-level precision and alternative solutions using IEEE 1588 Precision Time Protocol, discussing their economic feasibility and effectiveness in achieving the necessary synchronization for tasks such as breaker operations and synchrophasor measurements. The analysis includes statistical assessments of time deviations and their contributions to synchrophasor accuracy, reinforcing the need for reliable synchronization methods in modern smart grid applications.
