wanfauzan, If you're talking about the total load on the two synchronized generator-sets, that would only vary if the island load varied. If you're talking about the load on the two synchronized generator-sets "shifting" from one to the other, that would likely be a function of the diesel...

wanfauzan, This is most likely what Phil Corso is alluding to: ONE OUR OF TWO PARALLEL GENRATORS SHOWING REVERSE POWER ALARM | Automation & Control Engineering Forum And when he writes combustion-driven generator I think he really means combustion engine-driven generator. But, I've been wrong...

gilbertgrape87, SOLAR's implementation of A-B PLC hardware is really NOT a good example of PLC for turbine control. SOLAR have developed special modules for their units to use with the PLC. This negates one of the big reasons for using "off-the-shelf" PLC hardware--there are proprietary modules...

The really great thing about standards is: There are so many to choose from.

wanfauzan, That explains how the more heavily loaded unit tripped on underfrequency (when Unit 2 was tripped). Is the the typical profile of operation when the two units are synchronized and operating as an island? The frequency changes as quickly as it seems to on these charts? Or, only when...

gilbertgrape87, I knew it was going to be something like this. And, I also knew the information provided was going to be ... thin. To say the least. We don't know if you're talking about a DCS or a turbine control system (but I presume DCS, since it's EXTREMELY doubtful GE would warrant their...

GilbertGrape87, Congratulations, you are embarking on a journey MANY have started, and few have successfully completed. Can a PLC (Programmable Logic Controller), also known sometimes as a PAC (Programmable Action Controller) be successfully used as a turbine control system or a DCS...

wanfauzan, When asking about the load after the separation from the grid, I wanted to know what the load did. Did it remain constant at 5.0 MW, did it increase or decrease, or was it fluctuating slightly? How long were the two units operating in island mode before the trip occurred? It seems...

wanfauzan, 1) Which unit tripped due to under-frequency: generator 1 or generator 2? It's VERY difficult for me to understand how the two units can maintain frequency when separated from the grid which was supplying 200 kW. If the two diesels have identical control systems with identical...

kafi_chems89, The Mark V uses Control Constant values to enable and disable vibration sensors. It's entirely possible that someone changed the Control Constants used to configure the vibration protection algorithms and either intentionally or unintentionally disabled one of the inputs. You...

barindra75, Where did you read the Frame 5 step load capacity is 3.5 MW? 3.5 MW per minute? 3.5 MW per second? In general, most GE-design B/E heavy duty gas turbines (Frame 5s are considered to be in this group of gas turbines) have a manual loading rate of 30 seconds from no load to full load...

rollymts, Well, not every control system creates back-ups in the same manner--or uses the same terms for back-ups. So, sometimes you need to forget what you know from other control systems and follow the instructions you were given in the first response: "If you want an electronic back-up of...

rollymts, Your question is not clear. If you want to print a copy of the application code (the control logic) of a Mark VIe, you need to click on File|Print and follow the prompts. (You can use the 'Help' feature of ToolboxST to learn how to print the application code, also....) You should...

No. There is no chance to use the machine in your home country. The frequency difference is a HUGE factor and unless you have a VERY expensive frequency converter it cannot be overcome. It would be less expensive to buy a new washer in your home country.

CalvinD, Okay. This should be interesting.

CalvinD, Generally speaking if the DLN gas fuel systems are working properly there won't be a problem with exhaust temperatures during any combustion mode. You wrote: "... they related these modes to one of the values of the exhaust temperature. ..." Two things: First, can you list specific...

CalvinD, Positive- and Negative Lean-Lean are transitory combustion modes--you will only see them when transitioning from Lean-Lean to Premix (Positive Lean-Lean) and when in Lean-Lean while unloading from Premix (Negative Lean-Lean and Positive Lean-Lean). Extended Lean-Lean has been...

himeshvarshan, I've been trying to determine how to answer your second question, and I was hoping your response would include some clue as to whether or not you are actually working on a GE Mark* turbine control system or not. But, my hopes were dashed. Presuming you are working on a GE Mark*...

Not true. I have several legal VMs (Virtual Machines) running fully legal versions of MS-Windows XP and even MS-Windows 7. If you have the licenses for them they can be activated. I have even purchased hard drives through ebay with licensed copies of MS-Windows and been able to use the licenses...

oneye14, According to this person’s profile he is a student…. But he’s apparently not liking the books he should have to study and believes he can get a better education from the experts on this forum. (I am honored that he has placed his mentorship in our hands.) But reality can be a cruel...
