Dear all,
With more and more renewable non-synchronous energy coming onto the grid on the island of Ireland, each of the generators have been asked to carry out a RoCoF (Rate of Change of Frequency) study - to determine how each machine will react to fast grid frequency deviations (as much as 2Hz/second in Northern Ireland), to enable a higher number of renewables to operate.
I have a query around the operation of a 50Hz GE machine with MK5 controls which normally operates in pre selected mode with droop control enabled. I don't believe it will perform as expected by the grid operator.
I assume that the machine will not perform with typical 4% droop characteristics as the pre selected load controller will 'fight' against the droop controller. This assumption seems to be covered and confirmed in other posts I've read but I would like some clarification.
Will operating the machine in base or peak load encounter the same issues?
If so, can these controllers be disabled when the machine reaches the desired value, so that it operates in free governor action?
I would like to keep the new operating procedures (if any) as close as possible to the existing.
