摘要:
大跨越线路的杆塔高、档距长,反击闪络风险高,准确分析其雷击暂态过程,对于保 证特高压线路的安全运行具有重要意义。文中针对淮南—上海特高压工程南通—苏州段的大跨 越输电线路,分别建立了该线路雷击暂态过程的FDTD和EMTP模型,得到了大跨越线路的杆塔横 担与塔顶电压、导线电压和绝缘子串过电压,并开展了对比分析,结果表明:采用Hara提出的 杆塔多波阻抗模型,EMTP计算得到的横担和塔顶电压远大于FDTD计算结果;若不考虑感应分量 ,EMTP计算得到的导线电压大于FDTD计算结果;上述结果导致EMTP计算得到的绝缘子串过电压 远高于FDTD计算结果。
Abstract:
For accurate analysis of lightning surge response of large-span river- crossing transmission line to ensure the safety of a power system,FDTD and EMTP models of the Nantong-Suzhou river-crossing transmission line in the Huainan- Shanghai UHVAC project are built. The voltages of the tower top, crossarms, phase conductors and insulator strings are calculated via both of the models, and comparative analysis is carried out. It is concluded that: 1)EMTP a chieves much higher voltages of the tower top and crossarms than FDTD if the multistory transmission tower model proposed by Hara is used for the EMTP model; 2)EMTP achieves much higher voltages of phase conductors than FDTD if the induced voltage from the current in lightning channel is ignored; and 3)EMTP achieves much higherover voltages of insulator strings than FDTD.
