摘要

本文对500kv大容量输电系统进行了分析,并着重讨论了在稳态和暂态工况下并联电抗器的尺寸。因此,对线路对地故障条件下的单极自合闸行为进行了分析。由此论述了相电抗器和中性电抗器、电容联轴器和电感联轴器等因素对二次电弧消弧的必要性和影响。为了证明单极自动重合闸的可行性,对这些进行了研究。通过对中性反应堆影响的研究,开发了该系统的一个实例。首先对这些考虑进行了分析,然后基于ATP/EMTP的瞬态模拟进行了验证。

Transient shunt reactor dimensioning for bulk power transmission systems during normal and faulty network conditions
This paper presents an analysis of a 500 kV bulk power transmission system and the dimensioning of proper shunt reactors to be applied under steady state and transient aspects in particular. Therefore, the behavior of single-pole auto-reclosing under line-to-ground fault conditions is analyzed. Hence is described the necessity and influence of factors such as phase and neutral reactors, capacitive and inductive couplings on the extinction of secondary arc. Those are investigated in order to justify the feasibility of single-pole auto-reclosing. A practical example of the system is developed with respect to an investigation of the impact of neutral reactors. The considerations have been firstly done analytically and verified subsequently based on transient simulations using ATP/EMTP.
