Woodward GCP-30 Series Configuration

NOTE
The parameters for the speed/frequency controller influence the generator real power controller.
Parameter 54
F/P contr.type
----------------
Package Q, Option Q only
f controller: type THREESTEP / ANALOG / PWM
THREESTEP The signal to control the speed/frequency/real power is output via
the relay manager to any configured relay. You can use the following
functions of the relay manager:
• function 114 = n+ / f+ / P+
• function 115 = n- / f- / P-
Please note to wire an external RC protection (manual 37239).
ANALOG .... A control is done via the analog controller outputs to terminals
8/9/10. Selection of the type of the signal (mA or V) to be utilized is
determined in Parameter 58. If a voltage output is desired, and jum-
per m
ust be installed between terminals 8/9 (see manual 37239).
PWM ........... A control of speed/frequency/real power is carried out via a PWM
signal. The settings in the Parameter 59 "Level PWM" are to be used.
If a PW
M output is desired, and jumper must be installed between
terminals 8/9 (see manual 37239).
Three-position controller (standard; Package Q, Option Q: setting 'THREESTEP')
Parameter 55
Freq.controller
deadband 0.00Hz
f controller: dead band 0.02 to 1.00 Hz
Isolated operation The generator set point frequency is controlled in such a man-
ner that, in its adjusted state, the current value deviates from the ge-
nerator set point frequency by this configured
dead band at most.
Synchronization The generator frequency is controlled in such a manner that, in
its adjusted state, the differential frequency reaches the
dead band at
most. The mains or busbar frequency are used as the set point value.
Parameter 56
Freq.controller
time pulse>000ms
f controller: minimum frequency 10 to 250 ms
This parameter is the minimum ON time for the relays to be able to respond in a re-
liable manner to the raise/lower signals. The shortest possible time must be set here
to ensure optimum control behavior.
Parameter 57
Freq.controller
gain Kp 00.0
f controller: gain 0.1 to 99.9
The gain factor K
p
influences the operating time of the relays. By increasing the
number in this parameter, the operating time can be increased in the event of a cer-
tain control deviation.
