1. Either on the front panel or using ToolKit navigate to menu
" Load dependent start/stop" .
2. Configure the parameters below.
Value Comment
Reserve power The reserve power at the interchange point is to be considered for LDSS
All All generators shall start in case of a dead busbar (mains failure)
5 The base priority for the genset is 5
The generator rated power is not considered for LDSS
Equal The remaining hours until next service are considered for LDSS
Off No engine change will be performed
180 s The minimum running time is 180 seconds
3. Configure the LogicsManager function "LD start stop" as
shown in (Fig. 143) to enable LDSS if a start request in
automatic operating mode or emergency mode are enabled.
start stop"
Additional assumptions are valid for isolated operation (IOP), i.e. in
case of an emergency operation:
A reserve power of 80 kW on the busbar shall be maintained,
n
i.e. at least 2 generators are available in isolated operation for
redundancy because no supporting mains are present.
A hysteresis of 20 kW is required to avoid frequent starts and
n
stops.
The delay for adding another generator shall be 10 seconds.
n
The delay for adding another generator shall be reduced to 3
n
seconds if a generator at the busbar is operating above its
rated load (accelerated start of the next generator).
The delay for removing a generator from the busbar shall be
n
180 seconds.
