GPS and GLONASS constellations for better time synchronizing reliability
Marcelo Zapella, Lucas Barcelos de Oliveira, Richard Hunt · 2018
The demand for accurate time synchronization available 24/7 increases with the growth of critical substation applications, such as phasor measurement, merging units, traveling-wave fault location and current differential protection schemes. In order to yield the best accuracy and granularity from such applications, the use of a common, reliable and precision-time reference is essential.
