Dear,
The company I work for, we have 03 frame 7EA gas turbines and a steam turbine. Gas turbines operate with Mark V. Our system is connected to the National Interconnected System and operate in Droop mode, usually at part load.
Recently had an oscillation frequency due to a concussion occurred in the National Interconnected System. Our turbines were operating at partial load and the selected pre activated. Despite the pre selected to be activated, the power of the turbine varied. With this variation turbine exhaust pressure reached high exhaustion and off automatically.
Until then, I thought that when the turbine was in " Pre Selected" the power would not vary when an oscillation occurred in the national power system. I searched a few posts on the subject, but was still not very clear "Pre Selected"
Could anyone help me understand how the operation works when the turbine is activated with the preselected in droop mode?
In a material that found " Constant Settable Droop Design Standard of GE " explains about Droop, however would like to know where I can find the information on these parameters in the logic of the turbine, for example, the CSP file? But what points?
