Abstract
Directional overcurrent relaying (67) refers to relaying that can use the phase relationship of voltage and current to determine direction to a fault. There are a variety of concepts by which this task is done. This paper will review the mainstream methods by which 67 type directional decisions are made by protective relays. The paper focuses on how a numeric directional relay uses the phase relationship of sequence components such as positive sequence (V1 vs. I1 ), negative sequence (V2 vs. I2), and zero sequence (V0 vs. I0) to sense fault direction, but other concepts such as using quadrature voltage (e.g., VAB vs Ic) are included
定向过流继电器(67)是指能够利用电压和电流的相位关系来确定故障方向的继电器。有各种各样的概念来完成这项任务。本文综述了保护继电器进行67类定向判定的主流方法。本文重点介绍了数字定向继电器如何使用序列分量的相位关系，如正序列(V1 vs. I1)、负序列(V2 vs. I2)和零序列(V0 vs. I0)来检测故障方向，但也包括其他概念，如使用正交电压(例如，VAB vs. Ic)
