PHASOR MEASUREMENT UNIT
The L90 Line Current Differential System is provided with an optional phasor measurement unit feature.
This feature is specified as a software option at the time of ordering. The number of phasor measurement
units available is also dependent on this option. Refer to the
Ordering
section of chapter 2 for additional
details.

are used within protection relays. If these phasors are referenced to a common time base they are referred to as
a
SYNCHROPHASOR
. A vastly improved method for tracking power system dynamic phenomena for improved power system
monitoring, protection, operation, and control can be realized if Synchrophasors from different locations within the power
system are networked to a central location.
The L90 offers PMU features over two communication standards, IEC61850-9-5 and C37.118. The complete Synchropha-
sor implementation for Firmware version 7.0 is shown in the figure below.

Synchrophasor data as measured and calculated by phasor measurement units (PMUs) is very useful to assess the condi-
tion of the electrical power network. The IEEE C37.118-2005 standard defines synchrophasors and related message for-
mats to transmit synchrophasor data. Synchrophasor streaming via IEEE C37.118 has proven to work but the desire to
