科学技术的发展与进步,推动了我国电力通信系统的快速发展,许多的高新技术被应用到了电力通信系统之中,电力通信自动化设备也向着多样化的方向发展,以满足电力系统日益增长的对电力通信系统的要求,从而保证我国电力通信系统能够为客户提供高水平的服务。本文先是从三个方面对电力通信自动化设备进行概述,并说明电力通信系统的快速发展,给电力通信网络的管理和调度操作带来了很大的进步,又详细分析说明了我国电力通信网络的方式应用。

To ensure the multiplexing of power line carrier frequency,this paper needs to qualify the substation line with three-phase blocking.This paper discusses the problem of three-phase blocking.According to the carrier principle and frequency distribution requirements,it analyzes the necessity of three-phase blocking,and puts forward some problems of three-phase blocking,and through some examples to simply calculate whether the frequency could be reused,and whether using three-phase blocking.Finally it provides some advice for the real project.

This article analyzes the communicating requirements of real-time line monitoring for special power line.It also researches the root cause of the traditional OPGW fiber cable why it can not be broken flexibly to fulfill the requirements of power line from the standpoint of structure.Base on the above research,we propose a new OPGW Fiber Cable structure– Modified OPGW Fiber Cable.We analyze the feasibility of this new fiber cable applying to special power line from the point of material structure and actual operation.
