The White Rabbit Time Synchronization Protocol for Synchrophasor Networks

Within the context of time dissemination techniques for power systems applications, the paper discusses the use of the White Rabbit (WR) protocol for synchrophasor networks. Specifically, the paper presents a Phasor Measurement Unit (PMU) integrating the WR technology and its experimental validation with a focus on the synchrophasor phase estimation in steady state conditions, by using a PMU calibrator generating the reference signals. We further compare the accuracy of the developed PMU with other state-of-the-art time synchronization technologies for PMUs. i.e., Global Positioning System (GPS) and Precision Time Protocol (PTP), demonstrating applicability of WR for PMU sensing networks
