The application of precision clock synchronization technology based on PTP(IEEE1588) in traveling wave fault location system
Traveling wave fault location system is an important part in building strong smart grid. Global Positioning System( GPS)is now widely used as clock synchronization source. However, with the development of smart grid technology, GPS clock has exposed some limitations. A kind of traveling wave fault location network based on PTP(IEEE1588) is proposed in this paper. First, the synchronization principle of high-accuracy clock synchronization technology bades on IEEE1588 is analyzed. Then, structure of PTP(IEEE1588) based traveling wave fault location network is built. Last, redundancy scheme of PTP based time synchronization system for traveling wave fault location network is designed. Compared to GPS traveling wave fault location system, this one has such advantages as low cost, having nothing to do with climate, location and environment, and can meet the demand for clock synchronization among each traveling wave fault location system. Connected by Ethernet, GPS clock is not needed to be installed in each traveling wave fault location equipment. It is simple, reliable and of obvious superiority, playing great significance on maintaining safe operation of power and social stability.
