Huawei SmartLogger3000 User Manual

Parameter Description Remarks
Positive-
sequence
reactive power
compensation
factor in LVRT
During LVRT, the device needs to 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 this parameter 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 LVRT.
Negative-
sequence
reactive power
compensation
factor in LVRT
During LVRT, the device needs to 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 this parameter 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 LVRT.
LVRT active
current
maintenance
coecient
Species the active current proportional coecient
before and during LVRT.
Percentage of
LVRT reactive
current limiting
During LVRT, the device needs 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.
Threshold of
LVRT zero-
current mode
When Zero current due to power grid fault is set
to Enable, if the power grid voltage is less than the
value of Threshold of LVRT zero-current mode
during LVRT, the zero current mode is used.
Otherwise, the mode congured in LVRT mode is
used.
LVRT mode Sets LVRT mode. The options are Zero-current
mode, Constant current mode, Reactive power
priority mode, and Active power priority mode.
LVRT
characteristic
curve
Species the low voltage ride-through capability of
the device.
-
Deactivate grid
voltage
protection
during HVRT/
LVRT
Species whether to shield the undervoltage
protection function during LVRT or HVRT.
This parameter is
displayed when LVRT or
HVRT is set to Enable.
