You can configure these parameters under
Configure > Parameters > Power management rules > Configuration # > Power
reservation > Reserved power
, where # is 1 to 8.
Parameter Range
Default
Notes
Enable
Not enabled, Enabled Not enabled
Not enabled
: The PMS ignores the reserved power set point. Available power =
Nominal power - Consumed power
Enabled
: The system subtracts the reserved power from the available power.
Set point
1 kW to 9 GW
480 kW
The reserved power that the controller must subtract from the available power.
INFO
If this parameter is set too high, then heavy consumers might not be able to connect.
7.2.3 Power analogue outputs
You can configure an analogue output with a function for a power value in a section. The controller calculates this value from the
information from all the controllers in the section.
Assign the AC measurement function to an analogue output under
Configure > Input/output > Power management
. Select a
hardware module with an analogue output, then select the output to configure.

Section | PMS P avail.
[kW]
Analogue output 0 kW to 10 MW
The available power to supply the total load in the section from
gensets connected in AUTO mode.
Section | PMS P used [kW] Analogue output 0 kW to 10 MW
The power used from gensets connected in AUTO in the section.
Note: If you need the total power consumption in the section, use
Conn. P used
.
Section | PMS P nom. [kW] Analogue output 0 kW to 10 MW
The total nominal power for the gensets connected in AUTO
mode in the section.
Section | PMS P avail. [%]
Analogue output -100 to 100 %
The PMS available power as a percentage of the PMS nominal
power in the section.
This can be negative. For example, the gensets in AUTO mode
cannot supply the whole load, and a generator under
switchboard control is supplying power to the section.
Section | PMS P used [%]
Analogue output -100 to 100 %
The PMS power used as a percentage of the PMS nominal
power in the section.
Section | Conn. P avail.
[kW]
Analogue output 0 kW to 10 MW
The total available power from all the connected generators in
the section.
Section | Conn. P used
[kW]
Analogue output 0 kW to 10 MW The total load in the section.
Section | Conn. P nom.
[kW]
Analogue output 0 kW to 10 MW
The total nominal power for the connected gensets in the
section.
Section | Conn. P avail.
[%]
Analogue output -100 to 100 %
The total available power as a percentage of the connected
nominal power in the section.
Section | Conn. P used [%] Analogue output -100 to 100 %
The load as a percentage of the connected nominal power in the
section.
