I am having a problem with the sharing of VARS between these 2 kinds of regulators!! I shall explain the system in detail, hope you can help!
Firstly,
I have three generators of 1000 kVA rating wired to a Basler SR4A regulator. As I recently required a power upgrade, I added a fourth generator of a 1400kVA rating wired to CDVR. The CDVRs voltage bias is fed by a Easygen 3500.
I added the fourth gen CTs to the cross current compensation circuit of the other 3 gens(note: without the burden resistor as specified in the CDVR manual).
My problem is that the VARs are not sharing, as soon as I parallel the two gens, either one of them takes all the kVARS and the other goes negative. I try increasing the voltage of the lower one, it brings the kVARS but within little time it either goes to maximum and the other one goes to negative kVARS and keeps fluctuating one way or the other.
Kindly help!
Thanks,
Mike
