Table 5-1 Starting the array using the black start function in o-grid mode
Task Procedure
Checking
parameter
settings
1. Log in to the SmartLogger WebUI.
2. Choose Monitoring > Inverter > Running Param. >
Feature Parameters and ensure that Microgrid
compatibility is set to Enable.
3. Choose Monitoring > PCS > Running Param. > Feature
Parameters and ensure that Working mode is set to
VSG.
Triggering black
start
Trigger black start on the MGCC.
Determining the
black start
capability of the
ESS
Use the MGCC to determine whether the ESS meets the
black start conditions based on the dischargeable power
and capacity of the ESS before power-o.
Preparing for ESS
array black start
Use the MGCC to send a black start preparation command
to the SACU.
Setting up the AC
voltage
After ensuring that the MGCC receives the state of black
start preparation success, send a black start voltage setup
command to the SACU.
NOTE
If the AC voltage is not set up within a certain period of time, the
MGCC reports the black start failure. After the MGCC reports the
black start failure, start the procedure from "Determining the black
start capability of the ESS" again.
Starting the
SUN2000
After the black start is successful (the SmartLogger reports
that the black start voltage setup is complete), the MGCC
starts the SUN2000.
