摘要

超高压输电线路单相故障后成功的单极开/重合闸程序需要对每个输电系统进行参数优化。介绍了非永久性故障单极开断后，输电线路横向参数和无功并联补偿参数对降低二次弧电流的影响。提出了一种减少三相系统基频表示中相间相互耦合的方法。利用ATP程序对优化后的中性电抗器在不同情况下的瞬态过电压进行了模拟。

Influence of transmission line transverse parameters in reduction secondary arc current during single-pole opening procedure

A successful single-pole opening/reclosure procedure after single-phase faults in the EHV transmission lines requires parameters optimization for each transmission system. This paper shows the influence of transmission line transverse parameters together with reactive shunt compensation parameters in the reduction of secondary arc current after single-pole opening procedure for non-permanents faults. It is proposed a method to reduce the mutual coupling between phases in a three-phase system representation at fundamental frequency. Some simulations of transient overvoltage for different cases with optimized neutral reactors were performed with the ATP program.
