35 kV线路单相间歇接地故障引发线路跳闸的原因分析

open access: yesDianci bileiqi
针对35 kV线路的单相接地故障扩大为同杆塔两相或三相接地故障问题,分析了35 kV线路单相间歇接地故障的发生、影响及绝缘子串最大风偏摇摆角的安全漏洞。结果表明,当35 kV线路单相绝缘子串间歇接地故障的接地分布电容电流续流不能自熄时,线路将发生单相持续间歇接地故障及非故障两相持续间歇过电压。其中,持续间歇接地故障电流电弧作为电弧源,将对故障点导线或故障绝缘子串及同杆塔非故障相绝缘子串产生影响,甚至有可能导致非故障相绝缘子串闪络线路跳闸;持续间歇过电压将对各种电气设备(包括绝缘子串 ...

基于配电网合环倒切接地故障分析的改进保护方案与合环条件

open access: yesDianci bileiqi
合环倒切操作凭借其不停电倒切负荷的特点,在城市配网小电阻接地方式改造及主变检修等过程中可有效提高供电可靠性。但合环操作会导致不同接地系统短时共存,线路倒切进原有接地系统会导致电容电流上升、负荷加重;若在此过程中发生单相接地故障,原有保护方案可能难以适用;且传统接地故障电弧模型未考虑实际电弧长度随机变化这一特征。针对此问题,在分析电弧发展机理的基础上提出了考虑电弧长度随机变化的改进Schwarz电弧模型,随后搭建不同接地方式共存的混合接地系统仿真模型,研究合环过程中单相接地故障位置对故障线路零序电流 ...
