Description
The faster the change in the
setpoint is to be carried out, the
greater the value entered here
must be.
5504 Frequency control
droop 2 0.0 to 20.0%
[2.0%]
If this control is to be operated on
a generator in parallel with other
generators and frequency control
is enabled, a droop characteristic
curve must be used.
Notes
Each generator in the system will
require the same value to be
configured for the droop
characteristic, so that when the
system is stable the active power
will be distributed proportionally
among all generators in relation to
their rated power.

86.25
[(08.17 Missing members OR
08.06 GCB fail to open) & 1]
If this LogicsManager condition is
TRUE, the frequency droop is
enabled.
Notes
For information on the
LogicsManager and its default
settings see
╚═▷ “9.3.1
LogicsManager Overview” .
The active droop will also be sent
to an ECU connected to the J1939
interface (CAN interface 2). This
information is independent from
the breaker states or active
controller (frequency or power
controller).
Example
• Rated power: 500 kW •
• Rated frequency setpoint:
•
50.0 Hz
• Droop 5.0% •
• Active power: 0 kW = 0% of
•
rated power
Frequency is adjusted to:
(50.0 Hz – [5.0% * 0.0 *
50 Hz]) = 50.0 Hz.
• Active power: +250 kW = •
+50% of rated power
Frequency is adjusted to:
(50.0Hz – [5% * 0.50 *
50 Hz]) = 50.0 Hz – 1.25 Hz
= 48.75 Hz.
• Active power: +500 kW = •
+100% of rated power
Frequency is adjusted to:
(50.0Hz – [5% * 1.00 *
