Mains Parallel Operation (mains interchange (import/export) power control)
The following example describes the configuration of a typical mains parallel operation with import/export power
control at the interchange point and load-dependent start/stop.
Multiple generators are to be operated in parallel to the mains maintaining a stable power at the interchange
point. The generators shall be started depending on the momentary load at the plant. An emergency operation in
case of a mains failure is also intended. The load dependent start/stop function (LDSS) shall be enabled with a
remote start request and during emergency operation. LDSS shall depend on the reserve power on the busbar. In
case of a dead busbar (caused by a mains failure) all capable generators shall be started and operated with their
minimum running time. No generator priority is considered. Generator selection shall be performed depending on
the operating hours.
The following assumptions are valid for this example:
•
3 generators, each with 80 kW rated power, are available.
•
The recommended minimum load for the generators is 40 kW.
•
The minimum running time is 180 s.
Configuring Load-Dependent Start/Stop
From the main screen on the unit select Parameter -> Configuration -> Application config. -> Automatic run con-
fig. -> Load dependent start/stop and configure the following parameters:
ID
Parameter
Value
Comment
5752
Start stop mode
Reserve power
The reserve power at the interchange point is to be considered for LDSS
5753
Dead busbar start mode
All
All generators shall start in case of a dead busbar (mains failure)
5751
Base priority
5
The base priority for the genset is 5
5754
Fit size of engine
No
The generator rated power is not considered for LDSS
5755
Fit service hours
Equal
The remaining hours until next service are considered for LDSS
5756
Changes of engines
Off
No engine change will be performed
5759
Minimum running time
180 s
The minimum running time is 180 seconds

function "LD start stop" as shown in Figure 4-2 on page 19 to enable LDSS if a
start request in automatic operating mode or emergency mode are enabled.
