为解决分布式馈线自动化故障判定过程中的可靠性问题，提出了配电网开关分组模型，依靠开关分组模型研究了开关拒分情况下的故障处理过程，并给出了一种基于逻辑运算的故障处理原则。对开关一次重合闸原则进行了补充，有效避免了开关拒分情况下的故障隔离范围扩大。对开关拒合情况进行了分析，增加了一种开关拒合情况下的二次重合功能，有效避免了开关拒合情况下的故障隔离范围扩大。分三种情况研究了相邻开关通信故障下的故障处理过程，并给出了一种统一的故障判定方法。对开关保护信号失灵分为互感器偶然性干扰及永久性故障分别进行了分析，研究表明偶然性故障对故障隔离无影响，永久性故障将导致故障隔离范围扩大。给出了实例分析，表明所提方法可行。

To improve the reliability of distributed feeder automation fault location, a distribution network switch group model is established. Based on switch group model, the failure process due to switch rejecting is researched. The fault handing principles are proposed based on logic operations. By supplementing the principle of single-shot reclosing, the extension of fault isolation scope is avoided effectively when the switch rejects to break. Through analyzing the switch rejecting to close, a secondary reclosing processing method is proposed to avoid fault isolation extending. The fault handling process is researched in three cases of communication failure of the adjacent switch. A uniform failure determination method is given. Incidental interference and permanent failure are discussed in switch protection signal failure. The research shows that incidental interference has no effect on fault isolation, while permanent failure will expand the scope of fault isolation. The results of many cases study show the feasibility and effectiveness of the proposed approaches.
