I was hoping MIKEVI would respond to this. I recommend the unit be shut down; at rest is best, but on cooldown or turning gear is okay. Power down the affected processor from the <PD> core. Disconnect the the cable(s) from the front of the card. BE SURE to confirm the cable...

hem_dipu, If the torque converter has a solenoid for spoiling have you checked that it's working correctly? What turbine control system does the unit have? Can you collect data or trends with the control system? What kind of controls does the diesel have? If it's electronic, it might be...

vwb5047, In all of the plants and control rooms and marshalling cabinets/rooms I have worked in, the earthing cables attached to the cabinets and ground bus bars were allowed to be in the same cable tray <i>in the same panel as the instrument cables.</i> In other words, for a very short...

bil07, Then I don't understand the problem as presented. If the time is coming from an IRIG-B master time source device then it should be picked up by the time synch card in the HMI and communicated to BOTH the HMI AND the Mark V. So, it seems something is amiss with the signal or the time...

bil07, Is there a clock/watch icon in the MS-Windows System Tray (at the far lower-right corner of the display, next to the HMI time)? If so, what color is the icon--white or green or red? I have a suspicion that the Time Synchronization feature is not set up correctly--it's getting a...

bil07, Also, how much does thew HMI/Mark V time differ from the proper time?

bil07, How old is the HMI? When did this problem start? What makes you think the problem is TIMESYNC.DAT? Does the unit get a master time signal from a IRIG-B or "GPS" time source? Does the HMI use NTP? If so, what color is the NPT icon in the System Tray?

MOmar91, There sure are a lot of oil problems at your site.... Some units have two L.O. Mist Eliminators--one for the turbine (and accessory and load compartment and #2 bearing), and one for the generator. How is your unit configured? A lot of times there is visible plume exiting the...

mahmoodalam, >What needs to be checked? <b>Specifically,</b> what alarm(s) are annunciated when the unit "trips"??? I'm going to admit--I know NOTHING about ABB turbine control systems, <b>BUT</b> I do know that unless one can read alarms and tell the alarm(s) which are annunciated when...

The cause of the high exhaust temperature spread is most likely that something wasn't reassembled properly. Liquid fuel nozzles, AA tips, cross-fire tubes, etc. If the unit has DLN combustors it may be that the high energy igniter ("spark plugs") may not be inserted at the proper depth, or are...

zoubi, If the machine is not under warranty and you and the plant owners feel you understand the situation and the risks sufficiently you are free to do whatever you want.

zoubi, Without understanding a LOT of details about how the plant and the grid are configured it's virtually impossible to say why. But, there may be a couple of reasons. First, a unit (gas turbine-generator) has to be configured to power what's called a "dead bus" AND it also has to be...

Aptx4869, Yes, because the issue is producing electrical power (MVA) without one hydrogen cooler. If necessary, you would have to MANUALLY limit the turbine to keep the electrical power below 155 MW, or 182.88 MVA. You would be trying to protect the generator, not the turbine. BUT, you...

Aptx4869, If I recall correctly, to determine the possible MW output rating for a synchronous generator nameplate rating given in MVA, one has to multiply the MVA by the rated power factor (from the nameplate). So, 228.6*0.85=193.8 MW, and if you then multiply 193.8 by the 80% (0.80) safety...

Farid26, When <C> isn't at A7, then it can't access its I/O--which includes the inputs and outputs connected to <CD>, as well as to the analog inputs to <C>. So, if you're sending commands to <CD> using discrete (contact) inputs when <C> is not at A7, <C> can't recognize them. <D> can't...

Hello, In my thinking and understanding, a plant black-out means there is NO electricity in the plant, that the grid supply is unavailable (the "HVCB" (High-Voltage Circuit Breaker??) open) is open and except for emergency lighting and emergency power (for Emer. L.O. Pumps and DCS, etc.)...

My 2 cents, FATs or SATs (Software Acceptance Tests) can be useful IF AND ONLY IF the people attending the FAT are familiar--very familiar--with the turbine and how it operates and are willing to "take the reins" and "drive" and ask questions when things don't behave as they expect. Most...

_Pioneer_, The basic process is as follows: --Run CARD_ID.EXE; the results will tell GE what PROMsets are used in the panel. --Identify the specific cards used for some applications (DCC/LCC, or SDCC/SLCC, etc.). --Make a copy of your unit-specific software to be used to configure...

rizwanheider, I found this: https://arstechnica.com/civis/viewtopic.php?t=939735 It's pretty old, but it might be helpful.... Another thought I had would be to look in the BIOS settings and see if there's a way to disable the auto HDD detection. If you can do that (if there are no...

rizwanheider, I was pretty certain this was the case.... If I recall correctly some HDDs had a jumper which could be used to enable or disable the automatic detection. It sounds as if the BIOS on the <I> you have is able to automatically detect the HDD and its size and so even if you...
