摘要
线路各端电流采样的同步问题是实现数字电流差动保护的技术关键。本文介绍数字电流差动保护中几种常用的和最新提出的采样同步方法，并对各种方法的特点进行分析和比较。
The problem of synchronous current sampling at all terminals of the line is the key technique in carrying out digital current differential protection. Several synchronization processing methods in common use and newly proposed ones are described in detail in this paper. Both features and shortcomings about these methods are analyzed and compared each other.
