Huawei SUN2000-75KTL-C1 - Setting Power Adjustment Parameters

Parameter Description Remarks
HVRT When the power grid voltage is
abnormally high for a short time, the
SUN2000 cannot disconnect from the
power grid immediately and has to
work for some time. This is called high
voltage ride-through (HVRT).
N/A
Threshold for
triggering HVRT (V)
Species the threshold for triggering
HVRT. The threshold settings should
meet the local grid standard.
This parameter is displayed when
HVRT is set to Enable.
HVRT compensation
power factor of
reactive power in
positive sequence
During HVRT, the inverter needs to
generate reactive power to support the
power grid. This parameter is used to
set the reactive power generated by
the inverter.
VRT exit hysteresis
threshold
Species the LVRT/HVRT recovery
threshold.
● This parameter is displayed
when LVRT or HVRT is set to
Enable.
● LVRT recovery threshold =
Threshold for triggering LVRT
+ VRT exit hysteresis threshold
● HVRT recovery threshold =
Threshold for triggering HVRT
+ VRT exit hysteresis threshold
Grid voltage
protection shield
during VRT
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.
Active islanding Species whether to enable the active
islanding protection function.
N/A
Soft start time after
grid failure (s)
Species the time for the power to
gradually increase when the SUN2000
restarts after the power grid recovers.
