Parameter 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.
LVRT gradient During LVRT, 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 LVRT
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
decreases by 10% during
HVRT.
LVRT active Specifies the active current
current proportional coefficient
maintenance before and during LVRT.
coefficient
Percentage of During LVRT, the device is
LVRT reactive required to limit the reactive
current limiting current.
For example, if you set
Percentage of LVRT reactive
current limiting to 50, the
reactive current upper limit of
the device is 50% of the rated
current during LVRT.
