Note:
Setting
#Run Hours Max Difference (page 200)
= 5 does not mean that gen-sets swap every 5 hours. The
Swap time is determined by the formula stated above. Please read the entire chapter Running hours
equalization for better understanding.
Note:
In the case
#Run Hours Max Difference (page 200)
is set to 0 and all gen-set in the group are at the same
initial point (RHE are equal), the gen-set swapping happens every hour.
Efficiency
The gen-sets engine priorities are automatically swapped to best fit to the actual load demand (load demand
swap - LDS). Also engine running hours are taken to the calculation (run hours equalization - RHE). This
function is activated via setpoint
#Priority Auto Swap (page 192)
= Efficiency.
Algorithm of function:
In the first step, the gen-sets are sorted according to their nominal power.
In the second step, the gen-sets with the same nominal power are sorted according to their RHE
The gen-set(s) with nominal power which fits the most actual load demand are chosen. From those with
same nominal power, the gen-set(s) with lowest RHE are chosen. Selection formula:
#Power Management Mode (page 192)
= ABS (kW)
Nominal power of gen-set > actual load
#Starting Load Reserve 1 (page 193)
#Power Management Mode (page 192)
= REL (%)
Nominal power of gen-set > (actual load demand × 100)/(100 -
#Starting Rel Load Reserve 1 (page
If two or more gen-sets are available for taking over the load always the one with the lowest CAN address is
chosen.
If load demand is higher than nominal power of the biggest gen-set, this one is fixed and the whole process
repeats from point the third bullet.
Example:
The system structure and its settings is shown on the figure below.
