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.

10.3.2.3 Local Power Control
If reactive dispatching instruction or dispatching target value is used as dispatching
input locally, the reactive control mode is set to "Local power control".
Step 1
Click "Power control" -> "Reactive power" to enter the reactive power interface.
Step 2
Set the "Reactive control mode" to "Local power control".
Step 3
Set local 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:At the start time, the locally configured
active instruction is sent to the power output port of the
inverter, thereby implementing reactive power control.
Closed-loop control: At the beginning time, reactive
instruction configured locally 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.
