Generator Load Sharing System

Here's the first thing I'd do.

READ THE OPERATOR'S MANUAL. If you don't have one, they can be found on the manufactirer's web site.

SDMO Diesel Generators

if that doesn't work, call the supplier and ask them how to do it.

Here are two papers that should get you started:

For paralleling the voltage regulators:

For paralleling the governors:

Go to Woodward.com and enter 01302_New-1.pdf in the search box

There is a lot more on Google when you search on Droop Compensation

You have a system that is working fine but you just want to know how it actually works. Is that right or is there a problem that you are attempting to resolve?

kW sharing related on frequency, KVAR sharing related on voltage. Sharing kW and kVAR, so what is the problem ?

You need to look at droop mode for stable parallel operation

as a novice to this particular setup, wouldn't it be advantageous to run two at 50% versus five at 20%. I realize you would need to optimize operating times/generators so that you maintained even wear.

OK shariqsaiyed, it's your turn to contribute to the discussion you started.

I think the load sharing ratio depend on the gorvenor of each generator, so you must read the operation of them.

With all the modules we can use today for sync. gensets, it's easier to do than trouble shoot. Without behavioral statistics of your system, the problem could be anything.

Generally, unsuccessful load sharing between gensets can be due to two major factors:

If you have a problem with your excitation control, one of your gens will be regulated at a different voltage level than others, and that will cause a reactive load sharing issue.

If you have a problem with your fuel control, one of your gens will be regulated at a different speed than the rest, and that will cause a KW sharing issue.
