摘要
为研究中性点不接地系统和经消弧线圈接地系统发生金属性单相接地时的暂态故障特征信息,文章利用MATLAB系统搭建了一个10 k V小电流接地模型,通过该模型对金属性单相接地故障进行了模拟,分析了小电流接地系统故障时暂态过程中的零序电流的特征信息。
In this paper, in order to investigate the transient fault feature information of metal single-phase ground in neutral point ungrounded system and the arc suppression coil grounding system, a 10 kV small-current grounding model is built by using the MATLAB system. The model is used to simulate the metal single-phase ground fault, analyzes the characteristic information of the zero sequence current in the transient process of the small current grounding system.
