摘要

针对常规保护配置不能满足中低压系统中多端线路快速全线切除故障的难题，提出了一种基于光纤通信的多端线路电流差动保护新方案。具体介绍了保护装置的工作原理、同步方式、通信方式、硬件构成及测试结果等。动模试验结果表明，所提出的多端线路光纤电流差动保护装置性能优越，完全能够满足T接线路全线速动切除故障的要求，在中低压系统中具有良好的推广使用价值。

Abstract

Focusing on the issue that the conventional protection relay is unable to clear the faults rapidly occurring within the whole protected multi-terminal lines in a medium/low voltage system

this paper presents a new scheme of current differential protection based on the fiber optical communication channel for multiterminal lines. The protection principle

the data synchronization

the communication mode

the configuration of hardware and protection functions are described in detail. The dynamical simulation test results show that the performance of the protection relay is excellent

which can completely meet the requirement of rapid fault clearing for lines with taps.
