本文提出了一种新的方法检测和区域定位的高阻抗故障（HIF）的不平衡配电系统。该方法被称为准差动零序保护（PQDSZ），它通过分析配电馈线上的电流零序有效值来检测这些故障。检测依赖于由两个测量点定义的差分区域。数据被发送到控制中心，控制中心分析接收到的电流之间的关系，并在检测到任何问题时发出警报。为了验证PQDSZ的有效性，给出了一个RTDS和真实的自动化设备的仿真系统。
This paper presents a new methodology for detection and area location of high impedance faults (HIF) on unbalanced distribution systems. The method is called Quasi-Differential Zero Sequence Protection (PQDSZ) and it detects these faults by analyzing the current zero sequence rms value on a distribution feeder. The detection relies on a differential area, defined by two points of measurement. The data is sent to a control center, which analyzes the relation between the received currents and send an alarm if any problem is detected. A simulation system with the RTDS and real automation equipment is presented, in order to validate the PQDSZ.
