| 摘 要： | 使用电磁暂态程序(electromagnetic transient program,EMTP),建立了750 kV同塔同窗同相序双回紧凑型线路模型。研究了全线或部分采用同塔同窗双回紧凑型线路时的潜供电流和恢复电压、感应电压和感应电流问题。结果表明,从限制潜供电流和恢复电压、感应电压和感应电流考虑,若线路装设高抗,则不宜在全线采用同塔同窗同相序线路。对此,可以考虑在线路主体采用常规型线路、仅在线路走廊紧张的路段采用同塔同窗同相序布置线路的方案。若同塔同窗同相序线路较短,则潜供电流和感应电压可限制在合理的水平内。对于无须装设高抗的短线路,若能解决开断感应电流问题,也可以考虑在全线采用同塔同窗同相序线路。
