Q-U Characteristic Curve
Configure the characteristic curve under instructions from professionals to ensure that the SUN2000 works properly.
The Q-U characteristic curve control mode is to dynamically adjust the ratio Q/S of output reactive power to apparent power in accordance with the ratio U/Un(%) of the actual grid voltage to the rated grid voltage.
Parameter |
Description |
|---|---|
Set this parameter to Q-U characteristic curve. |
|
Specifies the change interval of the reactive power for a grid-tied point. |
|
Under a specific grid code, after you set this parameter, the characteristic curve takes effect only when the actual output active power of the inverter is greater than the preset value. |
|
Specifies the number of characteristic curve points. The characteristic curve supports a maximum of 10 valid points. |
|
When configuring the curve, ensure that the U/Un(%) value of a point is greater than the U/Un(%) value of the previous point. Otherwise, the message indicating invalid input will be displayed. |
