Description
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.
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.
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.

Remarks
For example, if you
set LVRT reactive
power
compensation
power factor to 2,
the reactive power
generated by the
SUN2000 is 20%
of the rated power
when the AC
voltage drops by
10% during LVRT.
