摘要

行波差动保护以行波电气量构成，具有两个特点:行波是电压和电流的组合电气量，天然地包含了分布电容电流；行波是运动电磁场，传输时延是运动的必然属性。因此行波差动保护与电压等级、分布电容电流和线路长度无关。行波差动保护可以按照暂态电气量构成，也可以按照稳态电气量构成，前者动作速度快，后者抗干扰能力强。行波差动保护可以应用于交流线路，也可以应用于直流线路。文中首先综述了国内外行波差动保护技术的研究现状，然后系统地总结了行波特性，接着指出了行波差动保护实际应用面临的挑战，最后重点分析了行波差动保护在特高压交流输电线路、直流输电线路和半波长交流输电线路上的应用，并展望了行波差动保护的发展前景。

Abstract

Traveling wave differential protection(TWDP)is constituted by traveling waves and characterized by two features. First

traveling waves is the composite quantities of voltage and current and inherently contains distributed capacitive current. Second

traveling waves are moving electromagnetic field

whereas transmission delay is the in-evitable attribute of movement. Therefore

TWDP is independent of voltage level

distributed capacitive current and line length. TWDP can be developed by transient quantities or steady quantities. The former solution has a fast operation speed

whereas the latter solution has a strong anti-interference capability. TWDP can be applied to AC transmission lines and DC transmission lines. This paper firstly reviews the research status of TWDP technology at home and abroad

and then systematically summarizes traveling wave characteristics. Next

the challenges faced by TWDP technology are analyzed. Finally

this paper analyzes the applications of TWDP on ultra-high voltage(UHV)AC transmission lines

DC transmission lines

and half-wave length AC transmission lines. The prospects of TWDP technology are also presented.
