摘要
建立配网自动化数字通信网络是实现配网自动化的前提。采用光纤通信与载波通信相结合的方式,在主干网采用光纤通信方式,在分支处采用电力线载波通信方式,既满足配网自动化系统对通信性能的要求,又最大程度的节约了成本。给出了电力线载波通信方案,并针对中压载波技术速率低、频带受限等问题提出了两级载波结构与增加规约转换板等解决方案。
The building of automatic digital communication network is the prerequisite of the distribution network automation. By using the optical fiber in the trunk and the PLC in the branch, a high performance-coat ratio could be obtained. The author describes how to use the power line carrier communication technology for data transmission, and proposes the solutions to raise the speed and number of the channels.
