摘要
特高压线路的特点使雷电绕击成为特高压线路故障的重要原因,800 kV直流复奉线上海段线路较长且多处于开阔的郊区,易发生雷电绕击闪络。应用考虑各种客观因素对耐雷水平影响的改进EGM模型对复奉线±800 kV直流特高压输电线路的耐雷水平进行了仿真分析。
The UHV DC transmission line fault caused by lightning shielding is UHV line's characteristics. Appling with improved EGM modle which considered the factors effecting lightning resisting level, the emulation of Fu-Feng ± 800 kV UHV DC transmission line's lightning resisting level was analysised.
