Abstract
Time synchronization is an important aspect of modern electrical utility measurement practice. Presently, most applications are synchronized to the Coordinated Universal Time (UTC) time base by means of Global Navigation Satellite System (GNSS) signals, including GPS. GNSS signals are known to be vulnerable to jamming and spoofing attacks, making them a credible attack vector. Precision Time Protocol (PTP) allows for time synchronization across computer networks. Although it has been successful in the IEC 61850 substation environment, there are challenges with its use over wide areas, particularly over public networks. This paper presents an approach which uses microwave fixed wireless access technology to deliver PTP time synchronization across wide geographical areas where pure fiber optic solutions would not be feasible. Preliminary results from a demonstrator system in Ireland are discussed.
