China´s valuable experiences in defending large-scale and long-time blackouts

Power System is regarded as the largest and most complex artificial system, and one of the most important infrastructures. However, large-scale blackouts are rare events but unavoidable and ruinous, resulting in huge economic loss even major casualties. If the blackout was restored quickly, the loss would be reduced sharply. Large-scale blackout is unavoidable, but large-scale and long-time ones are not, as what happened in China in recent thirty years. In this paper, we discuss the key differences of China´s measures and experience in preventing and controlling blackouts from other countries in three aspects, including construction, operation and management, and the application of new technologies. A complete and effective system to defend large-scale and longtime blackouts is formed and adopted in China. It´s a valuable reference for smart electricity grid construction in most of countries.
