Description
When the power grid voltage is
abnormally low for a short time, the
SUN2000 cannot disconnect from the
power grid immediately and has to work
for some time. This is called LVRT.
Specifies the threshold for triggering
LVRT.
Specifies whether to shield the
undervoltage protection function during
LVRT.
During LVRT, the SUN2000 needs to
generate reactive power to support the
power grid. This parameter is used to set
the reactive power generated by the
SUN2000.
For example, if you set LVRT reactive
power compensation power factor to
2, the reactive current generated by the
SUN2000 is 20% of the rated current
when the AC voltage drops by 10%
during LVRT.
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).
Specifies whether to enable the active
islanding protection function.
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.
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.
