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

Dianci 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 ...
