8.3.2.2 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.
table 8-7 Parameter description
Parameter
Description
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.
Select energy meter /
transformer*
Unselected
Select Smart Energy Meter / transformer involved in power
regulation
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.
