The L30 is provided with an optional Phasor Measurement Unit (PMU) feature. This feature is specified as a
software option at the time of ordering. The number of PMUs available also depends on this option. Using the
order code for your device, see the order codes in chapter 2 for details.
5.5.8.2 UR synchrophasor implementation
Phasors are used in protection relays. When these phasors are referenced to a common time base, they are referred to as
synchrophasors. A vastly improved method for tracking power system dynamic phenomena for power system monitoring,
protection, operation, and control can be realized when synchrophasors from different locations within the power system
are networked to a central location.
The L30 offers PMU features over two communication standards, IEC 61850-90-5 and IEEE C37.118. The figure shows
complete synchrophasor implementation.
5.5.8.3 UR implementation of IEC 61850-90-5
Synchrophasor data as measured and calculated by PMUs is used to assess the condition of the electrical power network.
The IEEE C37.118 standards define synchrophasors and related message formats to transmit synchrophasor data.
Synchrophasor streaming via IEEE C37.118 has proven to work but the need to have a communication mechanism that is
compliant with the concept of IEC 61850 has led to the development of IEC 61850-90-5. The IEC 61850-90-5 technical
report defines the packet structure for multicast routing of streamed Sampled Value (SV) known as R-SV.
