35 kV系统中性点不同接地方式对铁磁谐振的影响研究

open access: yesGaoya dianqi, 2010
35 kV系统中铁磁谐振过电压频繁发生,对系统造成很大的危害。利用理论分析和EMTP-RV仿真相结合的方法,分析了中国35 kV系统3种中性点接地方式(中性点不接地、经消弧线圈或小电阻接地)下由电磁式电压互感器(PT)饱和引起的铁磁谐振过电压,研究结果表明,在中性点经消弧线圈或小电阻接地系统中,只要消弧线圈或小电阻的参数选取合适,能够将中性点位移电压限制在电压三角形内,可有效抑制铁磁谐振的发生。

An efficient deep learning based scheme for adaptive auto-reclosing in power transmission lines

open access: yesAlexandria Engineering Journal
As a large percentage of faults in transmission lines are single-line-to-ground (SLG) and transient in nature, the use of adaptive single-phase auto-reclosing (ASPAR) schemes is essential.
