10.3.2.2 Remote Power Control
When the instruction source is IEC104 or MODBUS TCP protocol, set the "Reactive
control mode" to "Remote power control".
Step 1
Click "Power control" -> "Reactive power" to enter the reactive power interface.
Step 2
Set the "Reactive control mode" to "Remote power control".
Step 3
Set remote dispatching parameters. For specific parameter description, refer to the
following table.

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.

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.
