Parameter
Description
Remarks
4
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).
-
5
HVRT triggering
threshold
Specifies the threshold for triggering
HVRT.
The threshold settings should meet the
local grid standard.
This parameter is displayed when
HVRT
is set to
Enable
.
6
HVRT reactive
power
compensation factor
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.
For example, if this parameter is
set to
2
, the reactive power
generated by the inverter is 20%
of the rated power when the AC
voltage drops by 10% during
LVRT.
7
VRT exit hysteresis
threshold
Specifies whether to shield the
undervoltage protection function
during LVRT or HVRT.
This parameter is displayed when
LVRT
or
HVRT
is set to
Enable
.
8
Active islanding
Specifies whether to enable the active
islanding protection function.
-
9
Voltage rise
suppression
The standards of certain countries and
regions require that the SUN2000
should prevent the grid voltage from
rising by delivering reactive power and
decreasing active power when the
output voltage exceeds a certain value.
-
10
Voltage rise
suppression reactive
adjustment point
The standards of certain countries and
regions require that the SUN2000 must
generate a certain amount of reactive
power when the output voltage exceeds
a certain value.
This parameter is displayed
when
Voltage rise
suppression
is set to
Enable
.
The value of
Voltage rise
suppression active derating
point
must be greater than
that of
Voltage rise
suppression reactive
adjustment point
.
11
Voltage rise
suppression active
derating point
The standards of certain countries and
regions require that the active power of
the SUN2000 be derated according to a
certain gradient when the output
voltage exceeds a certain value.
12
Soft start time after
grid failure
Specifies the time for the power to
gradually increase when the SUN2000
restarts after the power grid recovers.
