Blackout is a condition that a certain transmission grid， large portion of interconnected transmission grids or networks experiences a total loss of power. This condition is evidently unavoidable as stronger and more robust systems than Luzon Grid like Indian， Brazilian， North American and European networks have already experienced blackouts in the past few years. Restoration following up blackout is urgent and technically complicated up to the lost. This paper mainly focuses on the blackstart of generators and subsequent restoration of the entire grid. Following the occurrence of Luzon Grid wide blackout on July 14， 2010， this manuscript provides an overview and describes the key actions undertaken by the Luzon system operator（LSO） in restoring the Luzon Grid， and also gives suggestions for improvement based on those experiences. Difficulties encountered in the actual system restoration and certain measures needed to improve the restoration process are also discussed in this paper.
