Hi,

Could you tell us what type of mode the unit is operated?
At which "part load " this occuring?
Is that plant a combined/simple cycle ?
Is there any alarms annunciated during the event??
Do you have any trends to share for better overview and then troubleshooting as best as we can!

With more accurate informations you provide here, the best we can support you on this issue!
Controls Guy25.
 
What is going up, Exhaust Temp. ?? Can we see the spread ?? Are you on IGV Temp. Control ?? Do you have DLN fuel system ?? Can we see TTXM vs IGV angle vs Load in Mw ??
