Description
LVRT gradient
During LVRT, 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 LVRT
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
decreases by 10% during
HVRT.
