Abstract :
This paper proposes a novel architecture, compliant to IEC 61850, for a distributed IED based phasor measurement unit to be used in electrical substations. In particular, a measurement architecture based on process bus and sampled values synchronized with IEEE 1588-2008 is proposed, so that voltage and current signals are acquired by a Merging Unit, while the signal processing is performed on a IED (Intelligent Electronic Device) that uses a new algorithm for synchrophasor measurement, in compliance with IEEE C37.118.1-2011.
