PFService is getting confused with the flow direction of amps/scada data being received on the Scada devices of the feeder as there is no flow direction indication on the scada data. This issue is more pronounced when there are distributed energy resources present on the feeders which may actually result in the negative flow on the feeders. If a flow is reported by a scada device in such situations, power flow is unable to identify the correct flow direction. Also, we have seen issues with flow direction when a feeder is abnormally switched. When PFService is unable to identify the flow direction, it is resulting is suspect scada errors being generated on the feeders.
