Hello All,
I am Michel, I got some issues commissioning CDVRs. Please do help if you can.

I have 3 CDVRs connected as above for cross current compensation. My CDVR setting is enabled for Droop Compensation with droop at 0% and I am on AVR mode, could some one please help me as to why I am not able share kVARS. As soon as they sync they are stable and then slowly once starts increasing and other starts reducing. Amps slowly begin to rise. The CTs are in the right direction.
Is something missing in the drawing??
Appreciate any help possible!!

Droop at zero is not droop and not proportional control.
Same as a PID controller set at zero% proportional band. You have effectively disabled droop.
Dial in some droop and see what happens.
