摘要

消弧线圈接地系统配电网发生高阻故障时

其故障分布特征与不接地系统存在较大差异

现有故障检测方法存在难以检测等问题。基于此

构建馈线零序电流模型与各馈线综合零序电流模型

将二者进行对比

并考虑零序电流方向

可有效实现高阻故障的准确检测。该方法在消弧线圈接地系统配电网仿真平台进行验证

仿真结果表明所提方法可有效识别故障馈线

对促进配电网安全运行具有参考作用。

Abstract

When high-impedance faults occur in distribution networks with arc suppression coil grounded systems

their fault distribution characteristics differ significantly from those in non-grounded systems

and existing fault detection methods face challenges in effective detection. On this basis

a line amplitude comparison method based on instantaneous zero-sequence current is proposed. By constructing feeder zero-sequence current models and comprehensive zero-sequence current models for each feeder

and comparing these models while considering the direction of zero-sequence current

the method can effectively achieve accurate detection of high-impedance faults. This method is validated on a simulation platform for distribution networks with arc suppression coil grounded systems. Simulation results show that the proposed method can effectively identify faulted feeders. This research provides valuable reference for promoting the safe operation of distribution networks.
