Generator Reverse/Reduced Power Monitoring
NOTE
All percentage values refer to a percentage of the generator rated power (Parameter 17; page 75).
Function: "Real power not within the permissible range" - The real power measured in a single-phase or in a
three-phase system is below the configured limit value for the minimum load or below the configured value for
reverse power. By setting positive threshold values (minimum load monitoring), a shutdown can be performed
before the generator ends up in reverse power.
Parameter 151
Rev./red.power
monitoring ON
Reverse/reduced power monitoring ON/OFF
ON................ Monitoring of the generator reverse/reduced power will be per-
formed. The subsequent parameters of this function are displayed.
OFF.............. Monitoring is disabled, and the subsequent screens of this function
are not displayed.
Parameter 152
Rev./red.power
resp.value -00%
Reverse/reduced power monitoring threshold value -99 to 99 %
Reverse power monitoring: If the current value falls below the negative threshold
value for at least the delay time (
Parameter 153), the following alarm
class is initiated.
Reduced power monitoring: If the current value falls below the positive threshold
value for at least the delay time (
Parameter 153), the following alarm
class is initiated.
Issuing of class F3 alarm
Parameter 153
Rev./red.power
delay 0.0s
Reverse power monitoring delay 0.0 to 9.9 s
For the control unit to recognize a reverse/reduced power monitoring fault condi-
tion, the threshold value configured in
Parameter 152 must be exceeded without in-
terruption for this period of time.
