table 8-9 Parameters description
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.
Select Meter* Select a Smart Energy Meter for power regulation
Control Cycle*
Time interval of delivering dispatching commands
Range: 5~60s
AI Port AI1~AI4 available
Instruction Type
PF: set the power factor as the target value
%: set reactive power percentage
Min/Max
When Instruction Type is set to %, the lower and upper limit is
-100.0%~100.0%.
When Instruction Type is set to PF, the lower and upper limit is
-1~-0.8 or 0.8~1
Step
The minimum difference value between two consecutive power
dispatching commands
Hysteresis Range**
When Instruction Type is set to PF, dispatching output maintains a
power factor within the range of ±1.
The parameters noted with * refer to the parameters that need to be set only when Control
Method is set to Closed-Loop Control.
**Only when Control Method is set to Open-Loop Control and Instruction Type to PF or when
Control Method is set to Closed-Loop Control, a Smart Energy Meter is selected, and the
Instruction Type is set to PF, the parameter Hysteresis Range is settable.
