You need to consider the time critical nature of communicating the phasor measurements to the collector. How familiar are you with Synchrophasor systems? Are you planning on updating 30 or 60 times per second? You will also need time/frequency synchronization. Any idea how you plan to do this?

Here again, this is a time critical operation and you need to respond within 20mS. In this case, I would agree with TJF, the PRU would be the better approach.
