Black-start Scheme for China Southern Power Grid

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.
