Dear Sirs/Ma'am,
We have 2 nos. of GTGs of Siemens of 18MVA each.
As usual, these Generators consists of ISOCHRONOUS MODE, DROOP MODE and LOAD CONTROL MODE. However, there is an additional mode "FREQUENCY CONTROL" which can be switched ON along with DROOP/ISOCHRONOUS mode.
Can anyone elaborate what is the difference between FREQUENCY CONTROL ON mode and ISOCHRONOUS mode?
Please note that FREQUENCY CONTROL MODE is not an independent mode i.e. it can be switched on only with DROOP MODE or ISOCHRONOUS MODE.
