纵联通道运行中的几个问题分析

纵联保护在系统中占有很重要的地位,但其运行情况并不理想,其中通道部分是个薄弱环节。在专用载波通道中,收发信机质量及使用、通道参数测试及调整问题比较突出;而复用通道中,在保护与通道的配合上屡屡出现问题,通道设备双重化的问题也日趋严重。要解决这些问题,需要从配置、调试、维护、检验等各方面努力,要特别注意施工调试技术的完善及专业间的沟通交流。

Analysis of some problems in operation of pilot channels

Pilot protection is very important in power system,but its operation state is not optimistic, especially in channel. About carrier channel,some problem are very distinct, such as quality and using of transceiver,testing and adjusting of channel parameter. About multiplex channel, a large number of problems frequently happened in protection cooperating between channel and diplex equipment. To solve these problems, configuration, debugging, maintenance, testing, etc of protection and channel should be paid more attention, and the intercourse of speciality and perfection of constructing art should be especially considered.
