ahmedaj, Gas fuel flows out of different passages and orifices on the fuel nozzle assembly than liquid fuel. The most common cause of high exhaust temperature spreads ON ANY FUEL is plugged fuel nozzle orifices. It's most likely the gas fuel nozzle orifices of one or more fuel nozzle...

Frank, Can you tell us what reference you are citing? Are you familiar with the power triangle? Excitation (field current) controls the length of the VAr component, and the torque provided by the prime mover driving the generator controls the length of the Watt component. Are you...

gpk, Hmmmm..... One always wonders what prompts questions like this.... CIMBRIDGE is a GE proprietary MS-Windows service which allows CIMPLICITY to communicate with GE Mark V and GE Mark VI turbine control panels. TCI is a GE proprietary MS-Windows service which allows alarms and events...

Yeah, ... I'm going to chime in here and agree with CuriousOne and Bob Johnston and ask why the root cause isn't being investigated and resolved? I'm also going to add that some kind of automatic transfer switch isn't probably the best answer, either. Finally, I'm going to add that on...

Hello, Dilip Nageshwar, Electronic communication using written English in all capital letters is very old technology. It was used in the 19th century (1800s) and 20th century for telegrams and teletype machines. In 2015, using PCs and smartphones, we have the ability to use an appropriate mix...

R10, This is an unusual gas turbine application, not unheard of, but unusual. Is it a single shaft unit or a two-shaft machine? It is virtually impossible to say for sure why the change in display, but the place to start is to find which ENUMDATA point is responsible for the indications...

Samson16, What happens when you type: dd2ip /? OR dd2ip /help at the command prompt? Usually, most of the IDOS and TCI commands have some limited--and cryptic--help available by using the /? or /help (sometimes it's just help) after the command and then pressing ENTER...

CuriousOne, I try to be pretty specific, and when I refer to issues with CIMPLICITY I'm referring to the way that GE (Salem, VA USA) implements CIMPLICITY on their HMIs--be it for Mark IV, Mark V, Mark VI or Mark VIe. The whole setup of the HMI is a mysterious moving target which is...

Balaurugan1983, Do you have access to the Operations and Service Manuals provided with the unit(s)? Can you get a copy of the Gas Fuel P&ID? Can you get a copy of the Control Specification document for the Mark VIe? Was any training done for operators/technicians prior to or shortly...

MArk6TA, > As far as I remember, Toolbox uses TCI and UDH to connect to the panel. Many times I've used TCI on PCs which aren't running TCI. I've used wireless PCs running Toolbox to do loopchecks in the field--and I only had Toolbox running on them--not TCI or CIMBRIDGE or CIMPLICITY...

CuriousOne, Hopefully this solves Wajid29's problem--and thanks for the information! > Open your Cimplicity Screen in Edit. DO NOT NAVIGATE to > different frames of the screens. Using the menu bar; go find > your properties for the screen and go to variables to ensure > "local_project"...

Sir, I will be happy to supply the required rectification. Every synchronous generator connected to the grid (of ANY size) requires a certain amount of energy (torque) just to get to synchronous speed. Any torque over that amount is converted to amperes by the generator. If every prime...

MakBan, > You are correct with our AVR is having trouble regulating when it hits OEL/UEL. > But what component of the AVR is malfunctioning? Is it the sensing circuit? Regulating > circuit? Or other circuits? Er, ..., Um, ..., I don't recall saying a regulator has or will have trouble...

Maythem, You want to trend: TNH (or TNH1) TNH_RPM THNA TNHAR FSR FSRSU FSRACC FSRMIN FSRN TTRX TTXM CSGV CSRGV But, you also need to have someone look at the application code to see how this low acceleration is being determined--is it that actual acceleration is less than...

MakBan, It's virtually impossible to say how your AVR operates without knowing the manufacturer and model of the AVR, but, in general, when an AVR is adjusted so that it's output reaches an overexcitation limit (OEL) or underexcitation limit (UEL) it's output cannot be raised or lowered...

davidmcc, RTD wiring for Speedtronic turbine control panels is ALWAYS something of an issue (due to the way GE usually wired them when they supplied the turbine-generator package--which was to use two-wire, twisted, shielded cables instead of three-wire, twisted, shielded cables). I suspect...

davidmcc, GE assimilated EGT into their portfolio. There was a crew of people back in the early 2000's which were sent to the former MAs (Manufacturing Associates, as they were sometimes called--licensed packagers of GE-design heavy duty gas turbines) to comb through their archives and find...

dennisbell, If you're an owner or operator, the Control Specification document provided with the Speedtronic turbine control system usually lists 'Expected Fuel Characteristics' in Sect. 05.nn.nn, which usually contains expected fuel flow-rates for various operating conditions (Firing; FSNL...

Rarely do I ever agree with Phil Corso, and this is no exception. How common is it for both bearings of a generator to experience oil flow problems simultaneously? I venture almost never. So, hence my recommendation to alarm on the average of each bearing's temperature sensors, and if both...

Maythem, Good questions. Since GE in Belfort, France, took over the responsibility for the Frame 9E (and Frame 6B and Frame 9F) units a lot of what was once standard sequencing has changed. This is not an alarm I'm familiar with and without being able to see the sequencing/application code...
