摘　　要：针对安徽电网500kV紧凑型长距离输电线路,由于配置并联电抗器及中性点电抗器,在某些运行方式下将产生谐振的现象,文章介绍了一种采用EMTP电磁暂态计算的软件,对启动方式及投运后常规情况下可能发生的基本运行工况进行了过电压计算和分析,达到更改启动方式,完成线路安全启动的作用。According to the phenomenon of resonance occurred in 500 kV long distance compact transmission line under some operation modes in Anhui Power Grid, due to the disposition of shunt and neutral reactor, the paper introduced a kind of software to adopt EMTP electromagnetic transient calculation. The over - voltage calculation and analysis of the basic operating conditions under the start - up mode and the conventional condition after putting into service were carried out, which can reach to change the start - up mode and play the role of completing safety start of line.
