Parameter
Description
LVRT
Specifies the low voltage ride-
characteristic
through capability of the
curve
device.
Grid voltage
Specifies whether to shield
protection shield
the undervoltage protection
during VRT
function during LVRT or
HVRT.
VRT exit
Specifies the LVRT/HVRT
hysteresis
recovery threshold.
threshold
VRT active
Specifies the percentage of
current limiting
the maximum active current
percentage
to the rated current during
fault ride-through (FRT).
VRT active
Specifies the recovery rate
power recovery
when the active current
gradient
recovers to the value at the
moment before FRT.
Zero current due
Specifies whether to enable
to power grid
the Zero current due to
fault
power grid fault function.
Zero current due
This parameter can only be
to power grid
set for the VDE4120.
fault
Voltage rise
The standards of certain
suppression
countries and regions require
that when the output voltage
exceeds a certain value, the
device must suppress a rise in
voltage by outputting reactive
power and reducing active
power.
