PMU - Synchrophasors With the ability of having up to 6 PMU elements in one device, UR devices provide simultaneous data streams of up to four different clients. UR devices exceed the IEEE C37.118 (2011) requirements for Total Vector Error (TVE) less than 1% over a range of 40Hz to 70Hz, and are able to measure and report synchrophasors over a frequency range from 30Hz to 90Hz with little effect on TVE. A special feature of the synchrophasor implementation is the ability to apply magnitude and phase angle correction on a per-phase basis for known CT and PT magnitude and phase errors. Selected UR devices can apply a phase correction on each phase of up to ±5° in increments of 0.05°. They also provide the ability to adjust for deltawye phase angle shifts or polarity reversal in the synchrophasor reporting of the voltage and current sequence components.

PMU recording

 UR devices include high accuracy metering and recording for all AC signals. Voltage, current, frequency, power and energy and demand metering are built into the relay as a standard feature. Current and voltage parameters are available as total RMS magnitude, and as fundamental frequency magnitude and angle. UR devices have 12MB of synchrophasor recording memory with multiple recording and triggering options. The PMU recorder can be triggered by an over/under frequency, over/ under voltage, overcurrent, overpower, rate of change of frequency condition, or by a userspecified condition, freely configured through FlexLogic. The PMU status flag shows which of those functions triggered the PMU recorder.

Precision Time Protocol - IEEE 1588

 UR devices support the IEEE 1588 v2 (2012) time synchronization protocol that enables time synchronization via the substation LAN with no sacrifice on time accuracy (1μs). IEEE 1588 removes the dedicated IRIG-B wiring and repeaters used for time synchronization that are traditionally used in substations. UR devices can stream PMU data through any of its three Ethernet ports using either IEEE C37.118 or IEC 61850-90-5 data formats. When streaming PMU data through a single port, a failover function can automatically switch the transmission over another Ethernet port. Selected UR devices also support up to 16 userdefinable command outputs via the command frame defined in the IEEE C37.118 standard.
