Is it possible to configure the minimum and maximum time delays that the openPDC waits for the data of the PMUs in the system arrive (also known as the “resynchronization buffer”)?
Yes, the LagTime and LeadTime columns in the OutputStream table are the “resynchronization” parameters. They operate is as follows: LagTime is a double precision number that defines the allowed past time deviation tolerance, in seconds (can be subsecond). It defines the time sensitivity to past measurement timestamps and is the number of seconds allowed before assuming a measurement timestamp is too old. This becomes the maximum amount of delay that can be introduced by the concentrator to allow time for data to flow into the system. LeadTime is a double precision number that defines the allowed future time deviation tolerance, in seconds (can be subsecond). It defines the time sensitivity to future measurement timestamps and is the number of seconds allowed before assuming a measurement timestamp is too advanced. This becomes the tolerated +/- accuracy of the local clock to real-time. Because the measurements being received by remote phasor devices are usually measured relative to GPS
