Q-U Hysteresis Curve (CEI0-16)
Configure the characteristic curve under instructions from professionals to ensure that the SUN2000 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 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 |
Description |
|---|---|
Set this parameter to Q-U hysteresis curve(CEI0-16). |
|
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. |
|
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. When configuring the curve, ensure that the Q/S values at points A and B are the same and set in sequence, and that the Q/S values at points C and D are the same and set in sequence. Otherwise, a message indicating invalid input is displayed. |
