摘要:
      2018年3月21日,因断路器过载保护动作后的一系列连锁反应,巴西电网发生大面积停电事故,北部和东北部电力系统与主网解列,导致北部和东北部14个州大面积停电,南部、东南部、中西部9个州也受到一定影响。文中介绍了事故前巴西电网的运行状况及事故的起因、经过、恢复等情况,指出事故前缺乏必要的稳定性分析、安控存在缺陷、保护误动作及“第三道防线”配置不合理是造成事故的主要原因,并结合中国电网实际,提出了重视保护及安控装置的整定与运行维护等保障电网安全稳定运行、防止大停电事故发生的建议。
Abstract:
      On March 21, 2018, a large-area blackout occurred in Brazilian power grid because of a series of chain reactions caused by a circuit breaker overload protection. As sequence, the northern and northeastern power grids were disconnected from the main power grid in Brazil, 14 states in north and northeast area came to blackout, and 9 states in south, southeast and midwest area were also affected. The operation status of Brazilian power grid before the accident and the cause, process and recovery of the blackout are introduced. It is pointed out that the main causes of the accident are the lack of necessary stability analysis before the accident, the defects in security control, the misoperation of protection and the unreasonable configuration of the third line of defense. Combined with the actual situation of power grid in China, some recommendations are put forward to ensure the safe and stable operation of the power grid and to prevent blackouts. For example, attention should be paid to the setting and operation of protection and control devices.
