Project Summary
The substationSBG administered by the Grid Protection Alliance (GPA) couples the high-performance phasor data processing features of the openPDC and the security features of SIEGate into a purpose-built
system that is both a substation PDC and a gateway for the secure, reliable communication of synchrophasor data from a substation to the control center. It acts as a synchrophasor data gateway in that it can securely and efficiently gather and redistribute high-resolution (e.g., 60 sample-per-second) time-series data from multiple devices and move real-time data in a consolidated stream to a central location, e.g., as upstream openPDC, and also keep a central data repository complete by providing automated data recovery capabilities using its short-term rolling local archive.
