enjep, This is an excellent question for either the company selling you the speed pick-ups, or the manufacturer (Dynalco).

Merabiko8, There was most likely a manual provided by--or available from--the ”hood” manufacturer. (Though I'm sure you're just interested in what signal(s) do I force to manipulate the louvers?” [I completely fail to understand the juvenile fascination with forcing signals.... But, then I am...

Merabiko8, Thank you for posting the attachment. Everything you asked is answered in the document. Find the control box and the actuator(s). Sorry I was wrong about the implosion doors--though these seem to serve a similar function.

'Load sharing' has many, Many, MANY different usages in power generation. The original poster asked about 'load sharing module' so I used my limited knowledge of some types of load sharing modules typically employed at power generation facilities. Actually, my (least) favorite definition/usage...

sukalaskar, Were the turbines/plant DESIGNED (intended) to operate independently of the grid (island operation)? These days when there are multiple generator sets (generators and their prime movers) to be operated in island mode there is also usually some kind of external 'power management...

Most of the reverse power protective relays I have worked with had inverse time delay characteristics--meaning the faster the rate of increase in reverse power the quicker the relay would act to open the generator breaker. Beginning with Mark* V turbine control systems, GE incorporated a reverse...

I couldn't resist reading this thread, based on the title/subject.... It gave me quite a chuckle, as did the questions. Merabiko8, I think you are referring to what are frequently called air inlet implosion doors in the turbine (axial compressor) air inlet structure (ductwork) of a GE-design...

Curious_One, You said the second coil will trip the generator breaker if the first one doesn't. amit0612 should be seeing an alarm SOMEWHERE if the something is trying to trip the generator breaker via the primary trip coil. This is just so typical of many plants and operators today: People...

RDCH, You would need to provide a LOT more information about the version of Mark (s), the version of the exhaust temperature spread algorithm (TTXSPVn) used in the Mark of both units, and some information about the TTXD1_n values of the two units. (I suspect at least one of the units uses...

Taki27, There are "diagnostic" alarms which can be annunciated during an AutoCalibrate procedure using Mark V (on the AutoCalibrate display). Many people just ignore, or don't see, these alarms. (Examples include things like 'feedback not changing;' 'excessive current;' etc.) I suggest that the...

Taki27, Thank you for the feedback/information. In 20 years of working on Mark V I have never had that problem. I have never known the Mark V to compare values in EEPROM with values in RAM and annunciate Diagnostic Alarms. Can you be more specific and provide the exact Diagnostic Alarm text...

Thank you for the feedback!

Taki27, So, if AutoCalibrate changes the values in TCQA RAM of <R>, <S> & <T> and those values are the VERY BEST LVDT scaling ("calibration") values, and then the AVERAGE values get loaded into the I/O Configurator and downloaded to EEPROM, doesn't that mean two things? First, the values in...

Hamada ramadan, It's my understanding of the GE PFR (Primary Frequency Control) that there is no way to limit the minimum load. There may be some unusual or new logic/sequencing/application code, but when the grid frequency is unstable there is no way to limit the frequency excursions of the...

madmaccc, There's really too little information to say with any degree of certainty what might have happened. If the unit has DLN-2.n combustors and I'm not mistaken I think there's a mode switch somewhere in this range--but I'm not 100% certain about that. That could have triggered an...

The original poster is talking about the secret unit having six (6) combustors, and that would be most likely a Frame 6F/FA, which would also most likely have DLN-2.x combustors. There are Frame 3's with six combustors, but I don't think they have DLN combustors--but I've been wrong before...

WE know you're there!!! We're waiting...!!!

Have a look at my (MANY) posts. I ask a LOT of questions, sometimes for the same requests which have been answered many times. I try very hard to be patient; sometimes I don't succeed. I get a few comments from other posters/responders that I have the patience of Job (though it's a nice...

There are LOTS of MODBUS forums around. See what kind of responses you get with your original post and nothing else.

I'm good with that. And, I've already reduced myself to your level. I'm going back up where the air is a little fresher; it stinks down here. Enjoy.
