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.
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 the threshold for triggering the HVRT.
The threshold settings should meet the local grid
standard.
During HVRT, the SUN2000 needs to generate
reactive power to support the power grid. This
parameter specifies the reactive power generated
by the SUN2000.
For example, if you set HVRT reactive power
compensation power factor to 2, the reactive
current generated by the SUN2000 is 20% of the
rated current when the AC voltage rises by 10%
during HVRT.
To meet the standards of certain countries and
regions, when the power grid voltage goes
through transient changes, the SUN2000 cannot
disconnect from the grid immediately and has to
work for some time. This is called transient
voltage jump.
This parameter specifies the threshold for
triggering transient voltage jump.
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.
