When a complete or partial blackout has occurred, the system operator is responsible for assessing the system condition, restoring the system based on the emergency operation procedures and re-establishing the integrity of the interconnection. This procedure is called blackstart. During the blackstart process, the system is operating in relatively weak condition, since the generation capacity is small in each blackstart path and there are plenty of different blackstart transients, such as transmission line energization, load pickup, generator synchronization, and island synchronization. In order to have a better understanding of blackstart process, dynamic behavior simulation, reply performance validation, and island synchronization are performed on the RTDS platform. In the future, RTDS will be utilized as the Real-time decision support tool for blackstart process.
