电弧故障是发生在埃及220 kV输电线路国家电网中最常见的故障，位于“亚历山大”市附近。在本文中，这220 kV TL网络在电弧故障期间的性能进行了研究，借助PSCAD/EMTDC程序连同一个专门设计的电弧故障自定义模型纳入该计划。对几种电弧故障进行了仿真，研究了电弧故障的主要特征。基于仿真结果，提出了一种自适应单极重合闸方案。所开发的计划被发现是有效的，在区分瞬时性和永久性故障，并在瞬时性故障的情况下，确定潜供电弧熄灭时间。
Arcing faults are the most common faults that occur in the 220 kV transmission line national grid of Egypt, in the vicinity of 'Alexandria' city. In this paper the performance of this 220 kV TL network during arcing faults is studied with the aid of the PSCAD/EMTDC program together with a specially designed arcing fault custom model incorporated in the program. Several arcing faults are simulated, and its main characteristics are studied. Based upon the simulation results, an adaptive single-pole autoreclosure scheme is developed and tested. The developed scheme is found to be efficient in distinguishing between transient and permanent faults and in case of transient faults, determine the secondary arc extinction time.
