The customer I am on site for is complaining that the GCV is oscillating. The calibration has been checked ok and the LVDTs seem fine. There are no issues for the speed pickups, p2 pressure transducers etc.
At FSNL the GCV is around 15% but oscillates up to about 3%. As they have also complained of the Liquid fuel oscillating, I have been looking at the speed control loop for FSRN.
At 22MW the oscillation/control is reduced at around 1% and looks ok with FSR around 38%.
SRV is rock solid also just controlling 0.5-1% movement.
This is a FR6 unit with a MK5 control. The speed control loop uses an FSRNV1 block. The constants in the big block are as follows:<pre>
FSKRN1 16.7% FSKRN2 12.7%/% FSRKN3 3.13%/%
FSKRN4 16.15%/% FSKRN5 0.06 and FSKRN6 0.5%</pre>
My question is regard to these constant. Can anyone compare and comment on the settings and can the correction factor constants FSKRN2, 4 be used to dampen this oscillations?
