Parameter
Description
Reactive power control
mode
Set this parameter to Q-U hysteresis curve(CEI0-16).
Reactive power
adjustment time
Specifies the change interval of the reactive power for a
grid-tied point.
Percents of trigger
frequency
Under a specific grid code, after you set this parameter, the
characteristic curve takes effect only when the actual output
active power of the solar inverter is greater than the preset
value.
U/Un(%)
When configuring the curve, ensure that the U/Un(%) value
of a point is greater than the U/Un(%) value of the previous
point. Otherwise, the message indicating invalid input will be
displayed.
When configuring the curve, ensure that the Q/S values at
points A and B are the same and set in sequence, and that the
Q/S values at points C and D are the same and set in
sequence. Otherwise, a message indicating invalid input is
displayed.
Q/S
Remote Communication Scheduling
The management system or independent power adjustment device sends scheduling
commands over the communications port that works with Modbus-TCP or IEC104, without
the need of user configuration or operation. The SmartLogger can automatically switch
between scheduling modes and send scheduling commands.
Parameter
Description
Reactive power control
mode
As the Remote communication scheduling mode has a
higher priority, the SmartLogger automatically changes
Reactive power control mode to Remote communication
scheduling after receiving a scheduling command from the
upper-layer management system.
If this parameter is set to Remote communication
scheduling, the SmartLogger parses the scheduling command
delivered by the upper-layer management system to valid
instruction data that can be identified by the solar inverters in
the PV plant and delivers the data to all solar inverters
connected to the SmartLogger.
