Communication networks and systems for power utility automation –
Part 90-5: Use of IEC 61850 to transmit synchrophasor information according to
Synchrophasor data as measured and calculated by PMUs are considered to be useful information to assess the condition of the electrical power network. The synchrophasors and related message formats to transmit synchrophasor data over long distances are defined in IEEE C37.118.
Even though the communication according to IEEE C37.118 has proven to be usable and work well, there is a desire to have a communication mechanism that is compliant to the concept of IEC 61850. This document lays out how this shall be done.
