Woodward GCP-30 Series Configuration

Manual 37278B GCP-30 Series - Genset Control
Page 40/174 © Woodward
Parameter 67
Start voltage
U control. 000V
V controller: start voltage 12.0 to 100.0 %
L This value refers to the generator set point voltage (Parameter 22).
The voltage controller will be enabled, once the generator voltage has exceeded
this value. This prevents an unintentional change of the set point of the voltage
regulator when starting the engine.
Parameter 68
Delayed. Start
U contr. 000s
V controller: delayed start 0 to 999 s
The start voltage of the voltage controller must exceed the threshold value for at
least this period of time.
Parameter 69
Volt.controller
droop 00,0%
only RPQ Package
V controller: droop 0 to 20 %
If the droop control is active, the droop portion configured here is considered for
voltagecontrol.
NOTE
The following parameters for the voltage controller influence the power factor cos ϕ controller.
Parameter 70
V/Q contr.type
----------------
Package Q, Option Q only
V controller: type THREESTEP / ANALOG
THREESTEP The signal to control the voltage/power factor is output via the relay
manager to any configured relay. You can use the following func-
tions of the relay manager:
• function 116 = U+/Q+
• function 117 = U-/Q-
Please note to wire an external RC protection (manual 37239).
ANALOG ..... Control is performed via the analog controller outputs to terminals
11/12/13. The type of signal (mA or V) to be utilized may be selected
in Parameter 74 and along with the instructions on the installation of
an external jum
per between terminals.
Three-position controller (standard; Package Q, Option Q: setting 'THREESTEP')
Parameter 71
Volt.controller
dead band 00.0%
V controller: dead band 00.1 to 15.0 %
L This value refers to the parameter "rated voltage in system" (Parameter 19).
Isolated operation The generator set point voltage is controlled in such a manner
that the current value will deviate from the generator set point vol-
tage by no more than the configured dead band.
Synchronization The generator voltage is controlled in such a manner that the dif-
ferential voltage will not exceed the configured dead band. The
mains or busbar voltage are used as the set point value.
Parameter 72
Volt.controller
time pulse>000ms
V controller: minimum voltage 20 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.
