Maximum PDC Input and Output

[Anil_Yeduvanshi]

Hi.

How many numbers of PMU inputs outputs can be configured in PDC?

Hi Anil,

Please refer to the following post to get an idea of the technical limitations.

Max Number of PMUs supported?

Hello Rex, There are no hardcoded limitations. Theoretically, a single openPDC will support up to 2^32 measurements (so as many PMUs as it would take to reach that measurement limit). In stress testing, the routing engine within openPDC was able to process data from nearly 2000 simulated devices. This does not necessarily represent any real-world limitations, and other parts of the system besides the routing engine may have their own bottlenecks. Thanks, Stephen

That said, I believe the theoretical measurement limit has grown since then to 2^64. The rest of the information there should still be accurate.

Thanks,
Stephen

Also note that for outputs such as IEEE C37.118 the restrictions may be higher just because of the protocol itself. The C37 the protocol supports a maximum of 65KB in a data frame.
