This article presents an accurate and robust method to calculate the phase offset of a reference waveform, usually produced by digital-to-analog converter (DAC) in IEC Std 61850-9-2 calibration systems. The is defined with respect rising edge clock signal, locked Global Positioning System (GPS). proposed relies on synchronous acquisition DAC output signal. In complex plane, where discrete Fouri...

This paper proposes an original Smart-Grid test bed aimed at teaching the IEC 61850 standard to students and professionals. It includes emulation of medium voltage loads generators, with a supervisory control data acquisition system. With this bed, lab classes focused on setup configuration protection relays using semantics xml language are proposed. For this, GOOSE services their functionaliti...
