摘要(Abstract)：

智能配电网中的断路器类型和数量较多,为了实现合理、有序的自动重合闸,有必要研究断路器的分类方法。文章提出一种基于故障后跳闸断路器信息向量和断路器类型及关联矩阵的断路器分类方法。定义断路器跳闸信息向量描述故障发生后跳闸的断路器,定义断路器类型及关联矩阵描述断路器类型及各断路器之间的连接关系,对上述2个矩阵进行乘法运算,可对因故障隔离而动作的断路器类型进行自动区分,并能指示待重合断路器之间的连接关系,为实现预期的自动重合时序提供依据。在此基础上研究了网络结构改变、断路器拒动导致故障隔离范围扩大、关键位置的断路器状态信息缺失等异常情况对断路器分类方法的影响,提出矩阵修正方案应对各种异常情况。算例分析结果验证了所提算法的正确性和可行性。
