6.7.6 Setting Parameters for Smart Reactive Power
Compensation
Context
The smart reactive power compensation algorithm obtains the power data of the
power meter at the grid-connection point through the SmartLogger, performs
intelligent algorithm analysis, adjusts the reactive power output of the solar
inverter/Smart PCS, optimizes the power factor of the grid-connection point, and
reduces or avoids power factor charge to increase the energy yield of the PV plant.
● Before setting the parameters, ensure that the solar inverters are connected to the
SmartLogger.
● If a power meter is connected to the SmartLogger, the power meter access procedure in
the wizard is only used as a check guide. If no power meter is connected to the
SmartLogger, add a power meter by following the wizard.
● Before setting the parameters, ensure that the license for smart reactive power
compensation has been loaded on the Maintenance > License Management page.
Procedure
Step 1 Set parameters as prompted. For details, click Help on the page.
Figure 6-77 Setting parameters for smart reactive power compensation (Scenario
Selection)
When the SmartLogger receives a remote reactive power scheduling command
from the PV plant, it automatically changes Reactive power control mode to
Remote communication scheduling. If power factor closed-loop control is
required, set Reactive power control mode to Power factor closed-loop control
and set the target power factor correctly.
For details about the running parameters of power meters, see 6.3.16.2 Setting Modbus-
RTU Power Meter Parameters.
