3 Generator Load Sharing Question

[ThePunisher]

HI all,

In one the facilities of our system, I can help notice this and took a photo.

All three generators are running under-loaded and the power factor is 1.09 of one and around 0.50~0.51 on the other two. If these generators are running in load sharing mode, why are their kvars or kVA not equal?

This is for my educational purpose only.

The fist approach for this is taking DG3 offline and check the offline voltage and compare this value with the data sheet. This voltage check should be done with a multimeter with a least 2 decimal place.

IF you can post a picture of the AVR and generator controller schematic.

Regards,
JS.

redlinej,

I will try to get it for you if I can and post it here later.
