Woodward easYgen-3000XT Series, Manual, Page: 404 / 1205

There are dedicated LDSS parameters for islanded parallel operation because the supply
of the load is important here.

Description
5760 IOP Reserve power 2 1 to 999999 kW
[100 kW]
The value configured for the
reserve power determines when
an additional generator will be
started. The reserve power is the
desired spinning reserve of a
generator or generators. The
reserve power is usually
estimated as the largest load
swing that a power plant may
encounter during the time it takes
to bring an additional generator
online.
The available generator power is
calculated by adding up the
generator real power ratings of all
generators with closed GCBs. The
reserve generator power is
calculated by subtracting the
power currently being produced
by all generators with closed GCBs
from the total available generator
power.
If the actual reserve power of the
generators is less than the value
configured in this parameter, the
next generator will be started.

Notes
This parameter is only effective if
start stop mode (parameter
╚═▷
5752 ) is configured to "Reserve
power".
It is also possible to change the
effective reserve power via
interface (refer to
╚═▷ “Remote
LDSS IOP reserve power ” ).
