摘要:

单相自动重合闸是保证电力系统安全与供电稳定的有效措施之一,在超高压电网中尤其明显。想要提高自动重合闸的成功率,必须对线路故障进行识别,避免盲目重合。通过基于ATP的电磁暂态仿真软件对超高压其中某一段线路模拟故障进行建模与仿真,研究了两种故障(永久性故障和瞬时性故障)情况下,一次、二次电弧的动态特性及其对故障电压的影响,EMTP仿真数据能有效区分故障类型,可靠地实现自动重合闸。

Abstract:

Automatic reclosing is one of effective methods to guarantee safe and stable power supply of power system, especially in EHV power system. To improve the automatic reclosing success rate, it is necessary to identify the fault line, avoid blind coincidence. In this paper, the electromagnetic transient simulation software ATP on EHV one line fault based modeling and simulation, dynamic characteristics of an arc, two times under the two kinds of fault arc shape and its influence on the breakdown voltage, the EMTP simulation data can distinguish fault types, to achieve reliable automatic reclosing.

Key words: Automatic reclosing, ATP-EMTP, the first arc, the second arc
