The cosφ-P/Pn characteristic curve control mode is to dynamically adjust the
power factor cosφ in accordance with the P/Pn (%) based on the VDE-4105 and
BDEW German standards.
Parameter
Description
Reactive power control
mode
Set this parameter to cosφ-P/Pn characteristic curve.
Reactive power
adjustment time
Specifies the change interval of the reactive power at
the grid-connection point.
Characteristic curve
points
Specifies the number of points on the characteristic
curve.
The characteristic curve supports a maximum of 10
valid points.
U/Un(%)
When configuring the curve, ensure that the P/Pn(%)
value of a point is greater than the P/Pn(%) value of
the previous point. Otherwise, the message indicating
invalid input will be displayed.
cosφ
Q-U Hysteresis Curve (CEI0-16)
If you do not need the SmartLogger to send remote reactive power control
commands, you can configure the characteristic curve as a substitute. The
SmartLogger delivers the values configured for the characteristic curve to the solar
inverter or Smart PCS, which then operates according to the configuration. The
SmartLogger no longer adjusts the values.
NO TICE
Configure the characteristic curve under instructions from professionals to ensure
that the solar inverter or Smart PCS works properly.
The Q-U hysteresis curve (CEI0-16) control mode is the Italian standard CEI0-16
version of the Q-U characteristic curve. It dynamically adjusts the output reactive
power of the solar inverter in accordance with the ratio of the actual voltage to
the rated voltage. The final value should be in the form of Q/S.
Parameter
