The combustion monitor software has built into it a facility which will increase TTXSPL by +200 Deg.F every time there is a system disturbance. Most frequently this disturbance is an adjustment to the turbine governor set-point. As soon as the disturbance is finished, TTXSPL will maintain it's...

Do you have a MKV Application Manual? If you have, take a look at Page 30 in Appendix B and Page 64 in Appendix D and this should explain all to you. If not, I will try and explain. The GEN & BUS voltage signals come from PTs usually installed in the Generator Control Panel. I/O config will then...

Difficult to understand what you mean. Do you mean 105% of ISO capacity? If yes, how do you intend to achieve this? Any real increase in capability is going to mean an increase in Exhaust Temp. which is going to mean an adjustment of the Control Spec. Is this what you mean?

The originator did say that this was a MS5001M, so it is an old machine and maybe has a "piggy-back" AC & DC Lube pump. Can this be confirmed? Can we see a copy of the L.O. P&ID ? If it is a piggy-back system, it does work a bit differently from the later systems with a full size AC Pump.

Middle two numbers are HP in thousands

A bit complicated, but let's take it one at a time. It very much looks like you started a fuel changeover and somehow initially you weren't getting gas flow, hence the drop in load. Then the gas came on and the load came back. The loss of excitation and breaker trip, you say the load dropped to...

Sounds to me like a servo valve or liquid fuel control valve problem. Could be a sticky servo valve just at that particular load and valve stroke. If you have a replacement servo, at least you can eliminate that. Is your hydraulic supply pressure steady and correctly set? Please report back with...

From this years Gas Turbine World Handbook GE PG9171E (126.1 Mw) = $US245/kW GE PG9351FA (256.15 Mw) = $US212/kW

First thing you need to do is go into ALARM.LST and see where this "stop from the generator control panel" comes from. Then go into the rung display and find out what initiates this signal and take it from there. If you have more details, trip logs, etc., please post them

To get the auto synch. to run, your system has to be within certain parameters of voltage and frequency. have you checked the synchro. page in the demand display when you are trying to synch. Is the Auto Synch. active, I think L83AS. Is 25P good "1", this is the synch. permissive. What is your...

Marco, Drop me an Email to bbobjohnston [at] gmail.com and I will send

Can you give some more detail on the trip during start-up. What Alarms do you get? Do you see the IGVs attempt to move ? Are you sure it is at 84% speed?

A question that has been asked for many years. What is better, using AUTOCAL or manually calibrating regulators using the Manual function in the User Defined Display pages. In the past and in past versions of Speedtronic, we didn't have AUTOCAL and had to do everything manually and it...

I have here for our units but Control Specs are very unit specific Denise. What do you want to do with it?

I have exactly the same problem here with a Frame 6 that has higher than normal vibration levels which go higher daytime than night time. I don't know you location, but here we get > 40 Deg. C daytime and 20-25 at night. Two problems, your L.O. header will probably be above spec daytime and, if...

Certainly sounds like a problem with the 20CS solenoid, do remember guys that 20CS normally ports oil to the hydraulically operated porting valve at the the inlet to the sequencing module. You didn't mention, but I would replace FH5 and FH1 which are the inline filters before and after PH3(88HR)...

98% of the time on GE Industrial Gas Turbines the cause of higher than normal vibration levels is imbalance or mis-alignment. Imbalance can be caused by FOD, IOD, errosion, corrossion, etc. Mis-alignmnet is self explanatory

Send me an Email to [email protected] and I'll send you a copy of the GE Time Synch. document which will explain all
