4.4.5.5.5 Mains Parallel Operation
General notes
In case of a mains parallel operation (MCB closed), load-dependent start stop is only
enabled, if the gensets participates in load sharing at the interchange point (all
participating gensets must be configured to the same setpoint).
A minimum load threshold must be exceeded to start the first genset, i.e. a genset will
only be started if a minimum load would be demanded from the generator.
There are dedicated LDSS parameters for mains parallel operation.

Description
5767 MOP Minimum load 2 0 to 65000 kW
[10 kW]
For the mains interchange
(import/export) real power control
to function, a minimum generator
power setpoint value is required to
start the first genset.
In many cases, it is desirable that
the engine is prevented from
starting unless the generator will
operate at a specific kW level or
higher to ensure a reasonable
degree of efficiency.
Example
The mains interchange must reach
a level that will permit an 80 kW
generator to operate at a
minimum load of 40 kW prior to
the engine starting.
5769 MOP Hysteresis 2 0 to 65000 kW
[10 kW]
Start stop mode configured to
"Reserve power":
If the reserve power is sufficient to
stop one genset without falling
below the reserve power threshold
and the hysteresis configured
here, a genset will be stopped.
If the generator load falls below
the minimum load threshold
minus the hysteresis configured
here, the last genset will be
stopped.
Notes
The importance of this parameter
depends on the setting of the start
stop mode (parameter
╚═▷ 5752 ).
It is also possible to change the
effective reserve power via
interface (refer to
╚═▷ “Remote
LDSS MOP reserve power ” ).
5768 MOP Reserve power 2 0 to 999999 kW
[50 kW]
The minimum reserve power in
mains parallel operation is
configured here. This is the
