电力线载波纵联保护通道可靠及安全性分析

Analysis of reliability and security of remote transmission protection channel over power line carriers

介绍了电力线载波纵联保护原理及其可采取的几种不同保护方式,深入分析了这些保护方式对通道的可靠性及安全性的影响,提出以载波纵联保护作为线路主保护时,必须通过合理的方式配置和正确的整定计算,使各种方式互相配合、互为补充,才能使保护系统具有较高的可靠和安全性能。文章末尾给出的应用实例,可作为上述结论的佐证。

The paper analyzes the reliability and security of PLC protection channel based on protection principle. In order to gain higher reliability and security of protection system, it′s necessary to make reasonable configuration of protection modes and correct regulation calculation when PLC remote transmission protection is taken as main line protection. These protection modes will be complementary each other. An application example is presented in the end.
