An Indian experience of defense against blackouts and restoration mechanism followed

In this paper with the background of evolution of regional electricity grids in India aiming at the formation of National Grid, Indian experience of running the electricity grid with the procedure established to safeguard the system against possible blackouts has been detailed. This has been followed by the restoration measures adopted earlier in the event of such occurrences and as envisaged for future, particularly in the context of four out of five regional grids operating in synchronism and the remaining one connected asynchronously with the rest.
