- Abstract:
- Monitoring, control and management of modern electric power systems require more and more extensively the use of distributed measurement systems capable of providing accurate data from remote measurement stations located in the network nodes. Synchronization between the acquisition devices is one of the most critical tasks in designing such systems, since in many cases the practical usability of the measured data strictly depends on how accurate the time reference used in the remote stations is. When highly accurate time synchronization is needed, satellite systems, like GPS, can be used to provide the required time reference. Given that equipping every measurement station with appropriate GPS receivers can result in excessive costs, in this paper the possibility of using Precision Time Protocol (defined in the Standard IEEE 1588) to disseminate the time reference provided by the GPS in an electric subsystem is investigated. Experimental results will be provided to evaluate the performance achievable with this solution in one of the most challenging measurement problems, that is represented by the measurement of synchrophasors.
