摘要
针对配电网中单相电弧接地情况,本文建立了准确可靠的电弧模型。文章在弧隙能量平衡理论的动态电弧模型基础上,提出了电弧通用模型以及不同特点的经典电弧模型,并利用Matlab/Simulink仿真环境对10k V电网中的单相电弧接地故障进行了仿真分析。文章所提出的经典电弧模型能准确、有效的反映配电网电弧接地故障的实际情况以及电弧性质。
This paper established an accurate and reliable model of arc for the case of single-phase power dis-tribution network arcing ground. This paper proposes an arc generic model and the classic arc model with different characteristics based on dynamic arc gap energy balance theory. At the same time, the paper simulates and analyzes 10kV single-phase grid arcing ground fault by using Matlab / Simulink simulation environment. The classic arc model can reflect the actual situation and the nature of the distribution network arc arcing ground faults.
