Inverter active power setting: overvoltage curve
The inverter may be capable of activating active power response to overvoltage at a programmable voltage threshold with
a programmable droop. There are five available modes
Fix gradient and non-
hysteresis: ∆P is the active power as a percentage of P
n
, the inverter provide non-hysteresis in the
control of active power response to overvoltage.
Fix
gradient and hysteresis: ∆P is the active power as a percentage of P
n
, the inverter provide hysteresis in the control of
active power response to overvoltage.
Variable gradient and non-
hysteresis: ∆P is the active power as a percentage of P
M
, the inverter provide non-hysteresis in
the control of active power response to overvoltage.
Variable gradient and hysteresis: ∆P is the active power as a percentage of P
M
, the inverter provide hysteresis in the control
of active power response to overvoltage.
The below figure descripts the difference between hysteresis and non-hysteresis control.
Here,

P : Active power in percentage during reducing
Intentional delay time for P(f) is only active for the activation of the function after the voltage over U
start
, and the
intentional delay time plus inherent dead time shall be less than 2s
Min. delay time for active power release is the delay time that the active power can increase after the voltage below U
reset
.
