| 摘 要： | 主要介绍了利用ATP和ATPdraw程序,对变电站及输电线路建立仿真计算模型,研究输电线路加强绝缘后,线路侵入波对变电站绝缘配合的影响,通过研究表明,针对湖南省电力系统现有的绝缘水平,220kV线路绝缘子调整至15片,500kV线路绝缘子调整至29片,对现有的绝缘配合不会形成威胁.

| Abstract: | The numerical simulation calculation models of substation and transmission line are established by electromagnetic transient calculation program ATP and ATPdraw and effects of strengthening line insulation on insulation coordination in substation are studied in this paper. The research shows that according to existing insulation level of power system in Hunan province, there is no threaten to current insulation coordination if the number of insulator is adjusted to 15 at 220kV level and to 29 at 500kV level. |
