Analysis on Blackout in Brazilian Power Grid on March 21, 2018 and Its Enlightenment to Power Grid in China
摘要
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, 14states in north and northeast area came to blackout, and 9states 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.关键词
