@PhilCorso I noticed that OP is not participate now..ControlsGuy25
OP only sent Fault Chart showing kW and PF. Furthermore, there is no mention from anyone, except you, that loads are inductive.
My calc illustrates Gen'r load consists of a large resistive component and a very small inductive component!
BTW, have you noticed that OP no longer participates!
Did you check the governor actuator and fuel rack mechanism are working fine or not???Hi ,
We have five 3512B CAT generators with Woodward 2500 synchronizing panels.
Have issue with generator one only(given name 1),So when this 1 gen. is online with any other generators, will be having load sharing issue specially at the time of sudden increase of load. At this time power factor leads to 0.1 and active power goes to negative and sometimes breaker trips because of reverse power. It happens once in a week or twice.
I have tried swapping Woodward 2500 from other generator, speed controller 2301 and also changed the PWM converter but still the results are same.
If need more data to analyze, i will provide it.
Sorry for the late reply, i was little bit busy these days.
As Mr. Udshred advised to check fuel racks , will be the good option at this time and also the CT.
I am attaching one picture of current load sharing, which is running good but if sudden load comes or the total load is very less, it starts giving reverse power.
power factor goes 0.1 and active power in negative.
This set up is on a land oil and gas rig.
I can see load gauge on generator1 fluctuates more than other generators while in synchronization.I CAN NOT UPLOAD THE VIDEO BECAUSE OF THIS WEBSITE RESTRICTIONS.View attachment 2618View attachment 2618
My opinion is... the Diesel-engine is at fault. Your opinion is... Generator electrics are at fault.
Only one person can resolve it... JSMHarrish.
So, JSM... you are up !
