User Manual 8 Grid Dispatching Function
Parameters Description
Reactive Power
Direction*
Forward Direction: The reactive power direction of the inverter
array displayed by the meter/transformer is the same as the actual
reactive power direction.
Direction Reverse: 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 commands
Range: 5~60s
The parameters noted with * refer to the parameters that need to be set only when Control
Method is set to Closed-Loop Control.
step 4 After finishing the configuration, click Save to apply the changes.

8.2.2.3 Local Power Control
If reactive dispatching command or dispatching target value is used as dispatching input
locally, set Reactive Control Mode to Local Power Control.
step 1 Click Power Control > Reactive Power to enter the Reactive Power page.
step 2 Set Reactive Control Mode to Local Power Control.
step 3
Set local dispatching parameters.

Parameters Description
Control Method
• Open-Loop Control: At the start time, the reactive power
command is sent to the power output port of the inverter for
reactive power control.
• Closed-Loop Control: At the start time, the reactive
power command is set as the target value, and the reactive
power and power factor are collected by the meter as
input parameters. A closed-loop control algorithm is then
used to calculate the proportional value of reactive power
compensation, which is then sent to the power output port
of the inverter. This method is generally used to improve the
power factor of the property boundary point.
