摘要：
在小电流接地系统发生单相接地故障时，80%以上会伴有接地电弧的产生，故障电弧具有随机性，会随周围环境的变化而变化。本文对电弧进行了简单的理论分析，着重研究电弧仿真模型的建立与分析。利用EMTP/ATP建立了弧光接地的故障模型，该模型将现场运行的干扰因素考虑在内，在技术上突破了以往搭建模型的理想模式，为小电流接地系统选线研究提供了数据支持，为后续的研究打下夯实基础。

Abstract:
When single-phase ground fault occurs in the neutral indirectly grounded system, more than 80%of the associated ground arc fault is introduce. Fault Arc is random, and change with the change of the surroundings. Arc is discussed simply in the theoretical analysis, and focused on the arc simulation model. Arc grounding fault model which the live interference is considered, is built in the EMTP/ATP. The model breaks the traditional ideal model, provides data support for the fault line detection in neutral point non- effectively grounded-system, and lays a solid foundation for the follow-up study.
Key words: Neutral un-effectual grounded system, Arc fault, EMTP/ATP, Simulation model
