Communication
abnormality output (%)
Communication is abnormal, and specified dispatch
output value is delivered.
Control method
Open loop control: Active instruction controlled by DI is
sent to the power output port of the inverter, thereby
achieving active power control.
Closed-loop control:
•
In case no Smart Energy Meter is selected, active
instruction controlled by DI is used as target value,
and active power compensation ratio is calculated
and sent to the power output port of the inverter.
Generally, this strategy is used for fast and accurate
active power regulation.
•
In case a Smart Energy Meter is selected, active
instruction controlled by DI is used as target value,
active power of the meter needs to be collected and
used
as
input
parameter,
and
active
power
compensation ratio is calculated and sent to the
power output port of the inverter. Generally, this
strategy is used for anti-backflow or avoiding zero
power feed-in.
