| 摘 要： | 为了减少潜供电弧的熄灭时间,确保单相自动重合闸的成功,研究了超高压输电线路上产生潜供电弧的机理和主要抑制方法。基于电路原理得出恢复电压和潜供电流的数学表达式,运用MATLAB编程得到恢复电压和潜供电流的数值。通过SIMULINK组建模块,仿真整个电路,得到恢复电压和潜供电流的波形图和数值,与理论计算值比较吻合。分析快速接地开关抑制潜供电弧的机理,在线路上安装快速接地开关后,弧道上的潜供电流和恢复电压都有了明显的降低。

| Abstract: | This paper presents the mechanism theory of secondary arc current generated in ultra-high-voltage(UHV) power transmission system and main suppressing method.The mathematic representations of recovery voltage and secondary arc current can be drawn by circuit principle.Utilizing MATLAB to write the program,the values of recovery voltage and secondary arc current can be obtained.It can simulate the whole circuit by SIMULINK and gets the waveforms of them.The effect of secondary arc suppression when the high speed grounding switch(HSGS) is adopted is studied.The mechanism of secondary arc restriction by HSGS is analyzed.The magnitude of the secondary arc current and recovery voltage in arc path are obviously reduced after installing HSGS on line.That in turn reduces the extinction time of the secondary arc and assures successful single-phase auto-reclosing. |
