• Now it should be possible to see the streaming synchrophasor data.
• Verify the communication by following the same steps as in section Verifying the
IEEE C37.118/1344 TCP communication.
9.6 Optical budget calculation for PMU - PDC
communication
Most of the times, the PMU IEDs are located in the substations. A local PDC might be
located in the substation. For communications within the substation or between the IED
and the WAN/LAN access point, it is important to know what is the optical budget
available. The graph in Figure
18 shows the dynamic range available for a PMU – PDC
configuration using typical OEMs.
