We have 6B gas turbine running at part load with grid import of 10MW. Suddenly Grid disconnected due to earth fault both GT's reached to the island mode. Both GT's on the DROOP mode. We were trying to keep one m/c on ISOCH mode & other on the Droop mode, but whenever ISOCH mode selection done on one m/c it is taking the full load of other DROOP mode GT. Before tripping of grid Gt-1 running 10 mW & GT-2 @ 20 MW part Load.
After tripping load increased for GT-1 to 15 MW & GT 2 on 25MW. What could be the problem for this? It is a 6B Gas turbine with liquid fuel operation.
