摘要
本文基于配网自动化系统平台,在分析和研究用于单相接地故障判据的诸多电
气特征量的基础上,构建了三维逻辑空间分析模型,提出了一种接地故障定位的新
算法。该算法综合考虑了配电网络中的各个节点呈现的电气特征和电气分布规律,
体现了逻辑“0”、“1”的等同贡献。文中还对算法的形成予以理论推导并给出算法
误差容错函数,具体算例的分析结果从多个侧面验证了该算法的正确性和有效性。

ABSTRACT
Based on the platform of Distribution Automation, this paper does some research
and analysis on several electric characteristics, from which single phase-to-ground fault
could be distinguished. In the paper, a logical space of model is built and a new logical
algorithm is proposed. This algorithm considers synthetically electric character of the whole
nodes of works and electric rules, and accept the effect of logic “0”, which play the
same role as logic “1”. Otherwise, the paper gives theoretical proof and evolution of how the
es into being, and defines error-admit function. Lastly, the algorithm is
validated by three examples in three aspects.
