I have scoured the site search with no luck. My question is in regards to our gas turbine not going into base load during 1x1 operation. The plant is a 2x1 combined cycle w/ GE 7FA's & D-11 ST. Control system is Mark VIe which was installed last year. We currently have a unit down for maintenance and have been running our online unit in preselect to follow dispatch. If we put the unit in "Baseload" from the Mark VIe, TNR will wind up and keep going passed 104.3%, FSR will go to 100% and will never go into Temp Control. When the FSR hits 100% turbine status will say "n/a". Again this only happens when we are 1x1, normally we run both units in "External Load" control and let our ADS dispatch control plant load through the DCS.
I have dug into the logic a bit but I'm having a hard time. If any more info is needed please let me know.
