There are dedicated LDSS parameters for isolated parallel opera‐
tion because the supply of the load is important here.
CL Setting range Description
[Default]
2 1 to 999999 kW The value configured for the reserve power determines when an additional
generator will be started. The reserve power is the desired spinning reserve
[100 kW]
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.

= Reserve power
Notes
This parameter is only effective if start stop mode (parameter
is configured to "Reserve power".
2 5 to 65000 kW If the reserve power is sufficient to stop one genset without falling below the
threshold and the hysteresis configured here, a genset will be stopped.
[20 kW]
Notes
This parameter is only effective if start stop mode (parameter
is configured to "Reserve power".
2 0 to 100 % If the generator load exceeds the threshold configured here, the load-
dependent start/stop function will start another genset.
[70 %]
Notes
This parameter is only effective if start stop mode (parameter
is configured to "Generator load".
The maximum generator load must be configured higher then the minimum
generator load for proper operation.
2 0 to 100 % If the generator load falls below the threshold configured here, the load-
dependent start/stop function will stop a genset. If only a few gensets are

operating in a multi-genset application, the IOP Dynamic (param‐
