Real Power Controller
Parameter 87
Power controller
ON
P controller: activation ON/OFF
ON ................ In mains parallel operation the real power is automatically adjusted
to the pre-selected set point (Parameter 46 or Parameter 47) when the
real
power controller is configured ON. The subsequent screens of
this function are displayed.
OFF .............. Real power control is not performed, and the subsequent screens of
this function are not displayed.
Parameter 88
power controller
ramp 000%/s
P controller: set point ramp %/s 0 to 100 %/s
Different set point values are supplied to the controller through this ramp in a per-
cent per second reference to the generator rated power (Parameter 32). The slope of
th
e ramp is used to determine the rate at which the controller modifies the set point
value. The more rapidly the change in the set point is to be carried out, the greater
this value has to be.
Power Limitation
Parameter 89
Power limit
P max. 000%
P controller: maximum power limitation 10 to 120 %
If the maximum real generator load is to be limited, a percentage based on the rated
generator power (Parameter 32) must entered here. The controller adjusts the gene-
rator in such a m
anner that this value is not exceeded. This parameter limits the set
point of the real power controller when the generator is in a mains parallel opera-
tion.
Parameter 90
Power limit
P min. 00%
P controller: minimum power limitation 0 to 50 %
If the minimum real generator load is to be limited, a percentage based on the rated
generator power (Parameter 32) must entered here, in accordance with the specified
settin
g limits. The controller adjusts the generator so that the real power generated
does not fall below this limit. This parameter is ignored in the case of fixed-set
point control or isolated operation.
