6.5.7.2
Setting the Frequency-Dependent Active Power Limitation
Parameter block
Some parameters must only be changed in the operating state "Stop". The entry will not be accepted in any other
operating state.
Procedure:
1. Make sure the inverter is in the operating state "Stop".
2. Call up the parameter overview (see Section 12.8.3, page 178).
3. If necessary, set the parameter
WCtlHzMod
to
CurveHys
.
4. Change the parameters
P-HzStr
,
P-HzStop
and
P-WGra
and save (see Section 12.8.4, page 178).
5. Save the parameter changes (see Section 12.8.4, page 178).
6.5.7.3
Setting the Frequency-Independent Active Power Limitation
Operation failure of the PV power plant due to incorrectly set parameters
If the parameter settings for grid management services are incorrect, the PV power plant may not be able to meet the
requirements of the grid operator. This can involve yield losses and the inverter may have to be disconnected by the
grid operator.
• When setting the modes of grid management services, ensure that the control procedures agreed with the grid
operator are parameterized.
• If the inverter is operated with a Power Plant Controller, ensure that the mode
WCtlCom
for active power
limitation and the mode
VArCtlCom
for reactive power control are selected in the inverter.
Parameter block
Some parameters must only be changed in the operating state "Stop". The entry will not be accepted in any other
operating state.
Procedure:
1. Make sure the inverter is in the operating state "Stop".
2. Call up the parameter overview (see Section 12.8.3, page 178).
3. Set the parameter
P-WMod
to the desired value.
4. Change the parameters belonging to the selected mode (see Section 13.3.2, page 191).
5. Use the parameter
PwrMonErrMod
to select the desired behavior in the absence of setpoint specifications as
follows (see Section 13.3.5, page 206).
6. If
SubVal
has been selected, enter the substitute values for normal feed-in operation and for operation outside of
normal feed-in operation.
7. In the parameter
PwrMonErrTm
configure the time lapse until recognition of the absence of setpoint
specifications.
8. Save the parameter changes (see Section 12.8.4, page 178).
