I have 2 150kw generators with Easygen 3000 controllers that autosynch the gens to the bus and auto load share. Normal operation is 1 gen online, 1 gen set for autostart. We parallel only to set up split bus for DP, and come off split bus back down to 1 gen. We also parallel to switch gens daily. Normal running load is hotel and blowers is about 90 amps when underway. Amperage varies on each leg by 3-10. Dockside with no blowers amperage load is about 30 without the air handlers and compressors running.
When both gens are in parallel, there is usually an uneven load share. It varies from 30-40 amps, sometimes lower if there is a small load (dockside). I don’t have a kvar meter on the easygen panel (at least not that I can find, there’s like 1300 possible settings on this fucking thing). Voltage on both gens is within a volt, cycles are even when in parallel, usually .1 or .2 cycles apart before synch. PF on one gen usually reads 1, and the other will usually show lag of around .85. RPM’s on the engines are 1800-1802 at synch.
How can I find KVAR? Replacing the diode ring on these gens requires swinging the gen according to the vendor who did it last (CT Droop was wired incorrectly at install) and I’m reluctant to let it ride even though shore support is blowing me off.
The best I can do to get these gens set to better load is to adjust voltage while only 1 is online. The voltage adjustment rheostat is overly sensitive to ship vibrations and doesn’t stay set and there is no way to lock it down short of glue or silicone, which I don’t think is the way to go. But that won’t get the PF to 1 on each anyway the best I can do manually is about .95
Need some advice here.
