Communication
abnormality output (%)
Communication is abnormal, and specified dispatch
output value is delivered.
Control method
Open loop control: Remote monitoring background is
connected and active instruction of remote dispatching is
sent to the power output port of the inverter, thereby
achieving active power control.
Closed-loop control: Remote monitoring background is
connected and reactive instruction of remote dispatching
is used as target value, reactive power and power factor
of the meter need to be collected and used as input
parameters, and reactive power compensation ratio is
calculated and sent to power output port of the inverter.
Generally, this strategy is used for improving the power
factor of the property boundary point.
Select energy meter /
transformer*
Unselected
Select Smart Energy Meter / transformer involved in
power regulation
Error limit (%)*
Adjustment accuracy If the ratio of the difference between
the reactive power and the target value to the rated power
is within the set error range, the target value is reached.
Adjustment ratio (%)*
If the adjustment does not reach the set target value,
increase or decrease adjustment value according to the
set adjustment ratio, so as to reach the target value.
Reactive power
direction*
Forward: The reactive power direction of the inverter array
displayed by the meter/transformer is the same as the
actual reactive power direction.
Backward: The reactive power direction of the inverter
array displayed by the meter/transformer is opposite to
the actual reactive power direction.
Control cycle
Time interval of delivering dispatching instructions
Parameter range: 5~60s
Note: *Only when the control method is set to "Closed-loop control", the parameter "-
Select energy meter / transformer" is settable.
