This paper proposes a new distributed architecture to measure synchrophasors in power substations, inspired by the standards IEC 61850. The new scheme is implemented in the process bus, where a high performance merging unit (MU), synchronized by precision time protocol (PTP), according to the standard IEEE 1588–2008, sends the sampled values (SVs) to an intelligent electronic device (IED) enabled...
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...
