Abstract

Power system blackouts result in complete interruption of the electricity supply to all consumers in a large area. Systems need to be planned and engineered in a way that minimizes exposure to and prevents cascading blackouts. Blackouts are caused by a sequence of cascading outages caused by a combination of multiple low-probability events (e.g., a transmission line sagging into a tree, hidden failures in equipment protection, the loss of multiple generation units because of a weather event, and aging equipment failure) occurring in an unanticipated or unintended sequence. The likelihood for power system disturbances to escalate into a large-scale cascading outage increases when the grid is already under stress. This stress can be caused by lower operational margins, overloaded equipment, and other factors, which are discussed in detail in this article.

意想不到的后果:全球停电经验和预防解决方案
电力系统停电导致大面积内所有用户的电力供应完全中断。系统的规划和设计需要最大限度地减少和防止连锁停电。停电是由多个低概率事件(例如,输电线路下垂成树、设备保护中的隐藏故障、天气事件导致的多个发电机组损失以及设备老化故障)以意外或非故意的顺序发生的组合引起的一系列级联停电引起的。当电网已经处于压力之下时,电力系统扰动升级为大规模连锁停电的可能性会增加。这种应力可能是由较低的操作裕度、设备过载和其他因素引起的,本文将对此进行详细讨论。
