A white rabbit synchronized PMU

Abstract

Within the context of time dissemination techniques for power systems applications, the paper illustrates the use of the White Rabbit (WR) technology with respect to its integration in Phasor Measurement Units (PMUs) networks. In particular, the paper refers to a WR network composed of a WR switch and WR modules integrated into a specifically-designed WR-PMU. The performance of the developed WR-PMU is assessed by means of a PMU calibrator, with a focus on the synchrophasor phase estimation in steady state conditions. The results show that the WR-PMU exhibits similar/better performance when compared to an equivalent PMU synchronized using the GPS. To further evaluate the developed WR-PMU, its performance is assessed in a WR network composed by two WR-PMUs connected to a single WR switch. The objective of this last experiment is to analyze the relative phase error between two PMUs when fed by the same reference signal provided by the calibrator.
