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
