Two turbines each with load of 15 mw and having capacity of 30 mw were running.
One was in isochronous mode and other in the droop mode. Station load was 28 mw and 2 mw export. I observed every time islanding occurred in droop mode turbine load decreases and in frequency mode turbine load increases if we do not change speed setpoint. Why is that in droop mode always load decreases during islanding and in frequency mode it increases and to what point it can go. Our droop is 5%. Please help me
