介绍了新一代电铁并补保护装置的功能特点和保护配置原理及判据，提出了提高差压动作可靠性以及多分支自适应保护方法。

The traditional traveling-wave differential protection cannot be applied to ultra/ extra high voltage transmission line with shunt reactor, so this paper describes a novel differential current expression. Based on traveling-wave differential protection a new scheme with low proportional restraint characteristic is presented.

传统的行波差动保护无法应用于带并联电抗器特/超高压输电线路，为此给出了一种新的行波差流表达式，并据此提出一种具有轻微比例制动特性的行波差动保护实用方案。
