中压配电系统的补偿一方面提高了供电质量，另一方面对接地故障检测和定位策略施加了更高的约束。三个新的算法检测永久性，电阻性单相接地故障进行了讨论。在网络中首次实施后，模型测试显示了重要参数对算法精度的影响，也适用于瞬时接地故障。最后提出了一种复杂径向结构补偿系统故障定位的新方法。
The compensation of MV distribution systems improves on the one hand the supply quality and imposes on the other hand higher constraints on earth fault detection and location strategies. Three new algorithms for the detection of permanent, resistive single phase earth faults are discussed. After a first implementation in the network, model testing showed the influence of important parameters on the algorithms accuracy, also for transient earth faults. Finally a novel strategy for fault location in compensated systems with a complex radial structure is outlined.
