8.3.2.3 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 Modeto Local Power Control.
step 3 Set local dispatching parameters. For specific parameter description, refer to the following
table.

Description
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.
Time interval of delivering dispatching instructions
Parameter range: 5~60s
Description
Communication is abnormal, and specified dispatch output
value is delivered.
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.
