摘要

本文介绍了一种新的线路保护原理，该线路一端(系统端)与大电力系统相连，另一端(变压器端)仅接在电力变压器或限流电抗器上。新的保护原理工作速度为1到2毫秒，覆盖整个线路长度，而不需要保护通道。新的原理是基于在线路系统末端测量的当前行波大小

A novel protection principle for ultra-high-speed tripping of lines terminated on transformers

This paper introduces a novel protection principle for lines connected to the bulk power system at one end (system terminal) and terminated exclusively on power transformers or current-limiting reactors at the other end (transformer terminal). The new protection principle operates as fast as 1 to 2 ms and covers the entire line length without the need for a protection channel. The new principle is based on the current traveling-wave magnitude measured at the system terminal of the line
