Pulsation monitoring on gas turbines is required because the combustion is operated close to the lean extinction limit to reduce emissions. The combustion flame instabilities are interacting with the flow and generate powerful acoustic waves. These waves excite the thermally highly loaded...

The pulsations in a gas turbine combustor are usually measured directly inside the combustor in order to have an accurate measurement across the full frequency spectrum of the pulsations. The conversion of the physical hot gas pressure fluctuation into an electric output signal (high frequency...

Did you check the all loop operating correctly I see that there is kind of amplifier in the data acquisition chain... Do you ok with the charge amplifier IPC620/628 also is mentionned in the manual ? would be good to ensure that it is ok Does the sensor need to be calibrated ? if yes when...

Greetings I would be glad to try to support you from France! Well what is OEM of the vibrometer Called ABE 028 ? Here some notes to understand better on puslation vs emissions .. Lean premixed combustion has become state of the art technology in gas turbines for power generation because of...

@Phil corso we can see that Gensets don't share equally KVAR Reactive load so....

Can you share process/diagnostic alarms list

Also one good thing would be to check proper operation on Flowmeter SPECIALLY 95BT-2 & 95BT-1 and others one

Hi Can OP give us a quick update here I got a frale 6FA manual showing how to deal the vent fan turbine compartment and inlet compartment

Hi Can OP give us a quick update here

Hi What I am tryin to do is to get a better approach and understanding of the utility behaviour regarding laod nature.. You mentionned that system wen to undervoltage it can be possible lile Reactive power is not shared equally between DG..

Here is also a good link to check https://dokumen.tips/documents/dln-1-combustion-system.html?page=1

Hello Have a read on this interesting article : https://www.modernpowersystems.com/features/featureachieving-sub-5-ppm-nox-with-e-class-turbines/

Hi We would need ki,nd of load balance list to understand better the behaviour of this Bus system /Island mode Behaviour

Hi Thank you for replying here and sharing such datas It would be great if you can share a kind of load balance list for better view of load consumers like galley equipment ...

Hi can you quick reply to keep us updated on that thread

@PhilCorso I noticed that OP is not participate now..

That was my asked question to original poster

Hi that would be nice to know at least OEM of this OTSG I know back in the days that Alstom had a satrt up procedure which can be found in the (contractual )manual called the Overall Plant control concept ( so the overall operating mode of the whole plant) It include schematics called Pfup for...

Is that following snippet is ineteresting for this query ?

Well power factor really means about the quality of the utility i means load consumers behaviour so it clearly depends on the nature of the load (inductive or capacitive) The Step up transformer deal with things like online/offline tap changer for Voltage regulation combined to the Generator...
