A IEEE1588-based system for synchronized PMUs and protective relaying functions

Synchronized measurement technology (SMT) has the potential of becoming the backbone these Intelligent Electronic Devices (EIDs). The major advantages of using SMT are that all measurement signals are attached with a high-accuracy time stamp. This PTP-BASED system is one of these systems and comprise three main technologies: a PTP slave LM3S8962 microcontroller, a floating point DSP (TMS320C6713) and a six simultaneous channel analog to digital converter (ADP8365) for the three current and voltage signals. For Master task a NI PCI_1588 card and a Symmetricom´s XLI IEEE1588 GrandMaster system for test. This paper provides the essays with two types of experimental systems: for substation and laboratory measurements and for high precision Synchronism test.
