Hi guys
Our plant is a combined cycle with DLN2.6+ Mark VI , the electric configuration its as shown (9FA GAS TURBINE)
my questions are:
what is necessary to happen to get in a island mode?
island mode is when there is a external failure and the turbine is disconnected (52G open) to the grid and keeps running in FSNL?
Another question related to other things ...if the unit in a start up keeps feeding the auxiliary equipment by the start up transformer (SUT) what could happen if I reach base load ? I mean if the operator forget to make the switch from the start up to the auxiliary transformer (we do that in 40 mw in GT)
both transformer are 9/12 MVA.
why do I need an auxiliary transformer...its only to not have to "purchase" energy form the grid?
Can I even reach based load with the SUT?
best regard
