摘要
输电线路发生单相接地故障引起的潜供电弧的随机性较强,为弥补模拟试验的不足,数字建模和仿真已成为研究潜供电弧的重要工具。鉴于此,提出了一种计算潜供电弧自熄特性的仿真模型,以特高压交流试验示范工程为例,计算了电弧的运动特性、电弧电流波形,得到了潜供电弧自熄时间,仿真结果与现场实测结果基本一致,表明所提出的潜供电弧仿真模型具有较大的工程实用价值。
To compensate the shortcomings of arcing tests, the numerical modeling and simulation method has become the important feasible tool to investigate and predict the characters of secondary arc. The simulation model for secondary arc in transmission lines was established. Secondary arc caused by single phase grounding fault in UHV AC demonstration project was taken as an example to simulate arc movement, arc current waveforms, and the duration time of secondary arc. The simulation results conform to the measured data in artificial test, which validates the simulation model of secondary arc fitting for the engineering application.
