Synchrophasors measurement in a GPS-IEEE 1588 hybrid system

This paper presents a study on a hybrid architecture considering Global Positioning System (GPS) and Precision Time Protocol (PTP), defined in Standard IEEE 1588, for applications in electric power systems, with reference to one of the most challenging measurement problems, namely the measurement of synchrophasors. The proposed approach refers in particular to situations in which many measurement devices, connected to each other by suitable communication links, are located in a geographically limited subarea of the power system. A laboratory experimental setup has been built to evaluate the performance achievable with this solution. A detailed analysis of the obtained results is presented
