| 摘 要： | 对长治—南阳—荆门1000kV特高压交流试验示范工程采用单相重合闸后的潜供电流、重合闸时间、过电压等问题进行了研究。通过仿真计算得到了特高压试验示范工程潜供电流和恢复电压水平,在此基础上对重合闸时间进行了分析,提出了特高压试验示范工程单相重合闸的时间应不低于0.6s。此外对重合闸过程中的清除接地故障过电压、重合闸过电压以及中性点小电抗的过电压问题也进行了分析,操作过电压水平均在允许范围内,中性点小电抗绝缘水平也满足重合闸要求。研究结果与系统调试结果相符。

| Abstract: | The problems such as secondary arc current,reclosing time and overvoltage of 1000kV AC power transmission pilot project from Southeast Shanxi via Nanyang to Jingmen in China are studied.By means of simulation,the secondary arc current and recovery voltage level of this 1000kV AC power transmission pilot project are obtained,on this basis,the reclosing time is analyzed,then it is pointed out that the reclosing time of single-phase reclosure should be not less than 0.6 sencond.Besides,such problems as the ove... |
