Our power plant consists out of 3 Heavy duty GE frame 9E gas turbines equipped with LEC-III (PSM) combustion systems and Mark V. For my internship research I'm investigating possibilities to install an autotune system on the GT's or to make a manual tuning model with only installing an Combustion dynamics monitoring system (CDMS).
Now the gas fuel split set point is fixed on 83,25% split and is only tuned after an outage. However, the gas splitter valve command stroke is around the 78,8%. This is the actual GSV command stroke. My question is what's the difference between gas fuel split set point from 83,25% and the command stroke of 78,8%? in other words what's happening in the Mark V to come to the stroke of 78,8% (Com ref. temp??)?
Hope to get an answer,
