The basic principles for the black-start scheme of China Southern Power Grid (CSG) and their implementing process are introduced

including the black-start scheme of the direct dispatching system and the reconstruction of the whole grid. The black-start scheme adopts a principle of action that starts up multiple areas and subareas simultaneously

and after the power of these areas is restored

through the connections between these areas and others

power transmission

and reconstruction of 500 kV main lines

the black-start process continues to increase the power amount and to strengthen the grid configuration until the whole CSG is up to snuff.
