No. Category Parameter Description Remarks
19 LVRT gradient
K1
During LVRT, the device must
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.
20 LVRT gradient
K2
During LVRT, the device must
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.
21 LVRT active
current
maintenance
coecient
Species the active current
proportional coecient
before and during LVRT.
22 Percentage of
LVRT reactive
current limiting
During LVRT, the device is
required to limit the reactive
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.
