Parameter Description
HVRT gradient During HVRT, the device must
K1 generate positive-sequence
reactive power to support the
power grid. This parameter is
used to set the positive-
sequence reactive power
generated by the device.
For example, if you set HVRT
gradient K1 to 2, the
increment of positive-
sequence reactive current
generated by the device is
20% of the rated current
when the AC voltage
increases by 10% during
HVRT.
HVRT gradient During HVRT, the device must
K2 generate negative-sequence
reactive power to support the
power grid. This parameter is
used to set the negative-
sequence reactive power
generated by the device.
For example, if you set HVRT
gradient K2 to 2, the
increment of negative-
sequence reactive current
generated by the device is
20% of the rated current
when the AC voltage
increases by 10% during
HVRT.
LVRT LVRT is short for low voltage
ride-through. When the grid
voltage is abnormally low for
a short time, the device
cannot disconnect from the
power grid immediately and
must continue to operate for
some time.
LVRT triggering Specifies the threshold for
threshold (V) triggering LVRT. The threshold
settings should meet the local
grid standard.
