I have an application that involves paralleling two sections of diesel generators. Here are the details:
"A" Section - 5 x 750 kW, 2.4kV, 60Hz
"B" Section - 5 x 500 kW, 480V, 60Hz
Each separate section utilizes the following load sharing:
Real Power - isochronous governor control with analog load sharing lines connected to Woodward 2301A controllers.
Reactive Power - reactive differential (cross-current) analog load sharing lines connected to Basler voltage regulators.
My specific question centers on reactive load sharing with paralleled units from both sections. Since the alternator voltage levels are different, I realize that the cross-current lines between the sections cannot be directly connected. I am assuming that some form of a VAR controller needs to be implemented that would control the signal on each separate cross-current loop.
Any recommendations and guidance would be greatly appreciated.
