Sundar2015, Why do you want to trip the unit on high bearing drain temperatures (this is oil temperature leaving the bearing, right?)? Have you, or someone at your site, had problems with high bearing drain temperatures causing a bearing failure so it's felt it's necessary to trip the turbine...

How does this analogy explain reactive power? If you were to be invited to my home on a fine summer afternoon and I served you your favorite beer in a cold glass with no head on it, what would be your first impression? "WOW! CSA is excellent at pouring beer--there's no head on it at all! He...

shakaramiali, You can learn a LOT about how GE Mark VI HMI's work by reading this thread: http://control.com/thread/1436261188 It has been established that CIMPLICITY 6.1 does not need a dongle, but TCI--at least version 3.05.10C running on MS-Windows XP--does require a hardware dongle...

MIKEVI & Wajid29, It seems the teaming of the two NICs for the UDH is not working. My experience is that GE typically uses the on-board Ethernet NIC as the UDH Primary NIC. Could it be that the new motherboard's on-board NIC MAC address needs to be entered in the teaming application? I don't...

vinayak, I've read some of your previous posts and it seems the liquid fuel may include naphtha--which is very corrosive. You said you check the calibration of the LFBV. I would be most interested to know how this was accomplished on a GE-design Frame 6B heavy duty gas turbine. Can you...

mbaviche, Another thing I'd like to mention is that if this is the first time you've encountered this particular Diagnostic Alarm you are pretty lucky--because some Mark Vs encounter this problem fairly frequently. Second, if this is the first time it could just be an anomaly (I'm...

Maythem, Thank you for the feedback. We like to say here at control.com, "Feedback is the most important contribution!"(c) because it lets others reading the threads know what was helpful--and what wasn't. Again, the Speedtronic turbine controls community has a pretty rich, active and...

HassanJ, Quite an important little piece of information that was neglected, wouldn't you say? Why would it be necessary to increase the exhaust temperature when operating in simple cycle (open cycle) mode? Does Earth's atmosphere need additional heat? And, the idea of changing the...

Jim, When the speed of G2 was increased, what did the governor say happened to the prime mover speed--did it increase, or did it decrease? Is your friend certain that the operator was increasing the speed of G2--because if the speed of G1 was actually being increased then the synchroscope...

HassanJ, I need to correct a statement.... >So, you have a choice--more electrical output and a lower ><b>overall plant heat rate</b> (which comes at the sacrifice >of gas turbine efficiency (higher gas turbine heat rate)), >or a more efficient gas turbine and a slightly higher plant...

ccjc81, What were the choices for the answer? When and why do you think the generator breaker should be closed when the unit is offline and on turning gear?

HassanJ, > There is an <b>idea</b> that the change will improve the heat rate<b>s</b> > by decreasing the angle as per advice. Well, if the GT exhausts into an HRSG, then increasing the exhaust temperature by closing the IGVs will certainly do that. In fact that's exactly what IGV Exhaust...

The 'TCCA Status S page xmit failure' alarm refers to the communications link between the Mark V and the EX2000, which uses Status S over the ARCnet link between the Mark V and the EX2000. The typical causes of this alarm are failed or failing coaxial and/or fiber optic cabling between nodes...

dax2172, Is this written somewhere in some official GE or control system packager document? How "near" to the gas turbine is "near?" On a pipe or some structural steel beam of the gas turbine or one of its auxiliaries? On a pipe or some structural steel not part of the gas turbine or one...

Who said?

Dontknowman, Thanks for the kind words. But there are many who would argue about my patience. I'm glad to be of help!

Mechnub, The air inlet filter house manufacturer specifies how the seams are to be sealed. Lately, it's just been stitch welding (a series of welds of approximately 25-40 mm, with a similar or slightly longer distance between them along the metal seams). If the metal is sufficiently rigid...

Wajid29, This is odd. I would suspect something is amiss in the TCI Control Panel Applet. Alarms/Events are special classes of communication, and TCI has to establish a connection to the Mark VI in order to be able to receive alarms/events and then pass them to the CIMPLICITY AMV Alarm object...
