Internal Time Reference Enhancement via White Rabbit Synchronization: A Power System Measurement Perspective

Nowadays, time-sensitive applications characterized by increasingly stringent synchronization requirements, covering ever-larger areas and an ever-increasing number of devices, are becoming essential in power systems. For this reason, the paper scouts the achievable synchronization accuracy through real-time industrial controllers using the promising White Rabbit (WR) technology. In addition, the implications in power system applications arising from the uncertainties introduced by synchronization are discussed. The obtained results show that WR protocol could complement GPS technology in several power system applications in the future, including harmonic synchrophasor estimation and traveling wave-based fault location.
