Mains Power Monitoring (not with RPQ Package)
It is possible to monitor two independently configurable generator power limit values. It is possible to output the
tripping to one of the freely configurable relays by means of the relay manager (relay manager function 67). This
function makes it possible to initiate external load shedding.
NOTE
With this function no centralized alarm is issued and no message is displayed. A relay output is
enabled which must be externally evaluated.
WARNING
This function does not operate as generator protection.
If generator protection is necessary, either the generator protection of this control (Parameter 178 and
Parameter 183) or an external protection dev
ice should be used.
Parameter 174
Mains power mon.
ON
Mains power monitoring ON/OFF
ON ................ The generator power is monitored (relay manager function 67 must
be assigned to one relay). The subsequent screens of this function are
displayed.
OFF .............. Monitoring is not carried out, and the subsequent screens of this
function are not displayed.
Parameter 175
Mains power mon.
res.val. I0000kW
Power monitoring threshold value I/E 0 to 9,999 kW
If this threshold value has been exceeded for at least the delay time (Para-
meter 177), the relay assigned relay manager function 57 energizes. Imported pow-
er is entered with a " - " before the value, exported power is entered with a " + " be-
fore the value. If the value is confirmed, the " - " becomes an " I " and the " + "
becomes an " E ".
Parameter 176
Mains power mon.
hysteresis 000kW
Power monitoring hysteresis 0 to 999 kW
If the monitored generator power level drops below the threshold value configured
in Parameter 175 by value configured here, hy
steresis occurs and the relay de-
energizes.
Parameter 177
Mains power mon.
delay 000s
Power monitoring delay 0 to 650 s
For the control unit to recognize a power monitoring fault condition, the threshold
value configured in Parameter 175 must be exceeded without interruption for this
peri
od of time.
