Wondering if anyone can confirm my assumptions about how to achieve frequency control mode on the Mark VIe... Our unit has always run in droop speed control as it is grid connected. Our black start procedure is asks us to start the GT (90 MW frame 7) as soon as possible, prior to re-establishing the utility breaker but there aren't any specific instructions for how to do this. My assumption is that by selecting "dead bus" from the GT1 synch menu the machine will know to operate on frequency control (isoch) instead of droop, however we have not ever attempted this and I cannot say for certain. Can anyone confirm or provide some more clarity on this for me?
