摘要:

2018年3月21日15:48,巴西发生了大停电事故,巴西北部和东北部电力系统与主网解列,切除负荷19760 MW,约占电网总负荷的25%,85%的州受到影响,造成巨大的经济损失。为避免大面积停电事故的发生,介绍了历史上历次大停电事故的主要过程及危害,总结了大停电事故的经验教训。从自然因素、设备故障、事故处理不当、策略失误等方面,分析了大停电事故的主要原因并提出了相应的改进对策。结合新能源接入、交直流混合电力系统、能源互联网、信息物理电力系统、人工智能等当前电网发展和研究的热点,提出应对大停电事故的主要研究方向。

Abstract:

At 15:48 on March 21, 2018, a large-scale blackout occurred in Brazil, the power grid in the north and northeast of Brazil were disconnected from main power grid. The load shedding was 19760 MW, accounted for 25% of the total load of the power grid, and 85% of the states were affected, resulting in huge economic losses. In order to avoid severe large-scale blackouts, the main process of blackouts in history was introduced, and lessons learned from blackouts were summarized from the aspects of natural conditions, equipment faults, manual mistakes, strategic mistakes and so on. The main causes of large power outage accidents were analyzed and the corresponding measures were put forward. Finally, combined with several development and research highlights of current power systems, such as renewable energy integration, AC/DC hybrid power systems, energy internet, cyber-physical power systems, and artificial intelligence, the main research directions of power system large scale blackouts were proposed.

Key words: power systems, large-scale blackout, cascading faults, energy internet
