摘要

导体断线故障是指线路电缆断线,可能接触或不接触地面。如果接触到地面,就会发生高阻抗故障(HIF)。这种特殊情况可能导致保护系统检测失败。这是由于HIF不能产生足够的故障电流来操作传统的保护系统或熔断器。另一方面,如果电缆不接触任何表面,上游保护设备将不会在其系统中检测到任何过流;否则,它将感应到电流减少,保护将不操作。为了在简单的保护逻辑中解决这一问题,本文提出了一种对称分量逻辑的实现,以增强传统的保护系统,主要是在有单相变压器的情况下。这些资产是不平衡负载的来源。此外,本文还提出了一种将所提出的逻辑实现到商用ied中的方法。最后,通过IED逻辑仿真软件展示了性能结果,并给出了现场性能。

Broken Conductor Fault Detection using Symmetrical Components in Distribution Power Systems - An Implementation Case
Broken Conductor Fault is an event where a line cable breaks and may or may not touch a ground surface. In case of touching the ground, a High Impedance Fault (HIF) can occur. This specific situation can lead to a detection fail for the protection system. It is due to the fact that the HIF does not produces enough fault current to operate conventional protection systems or fuse. On the other hand, if the cable does not touch any surface, the upstream protection equipment will not sense any overcurrent in its system; otherwise, it will sense a current reduction and the protection will not operate. To undertake this problems in a simple protection logic, this paper presents an implementation of a symmetrical component logic to enhance the traditional protection systems, mainly in a scenario where there are single-phase transformers. Those assets are source of unbalanced loads. Moreover, this paper presents a way to implement the logic proposed into the commercial IEDs. Lastly, performance results are showed through IED logic simulation software, and on-field performance is presented.
