摘要
根据中压配电网分支复杂，监控节点数量大，实时性要求不高等特点，提出了基于电力线载波通信（PLC）的通信方案，设计了基于ARM的载波通信终端的硬件，实现了PLC主要的软件功能，并对电力系统中影响PLC通信的因素进行了分析，在硬件和软件方面采取了合适的抗干扰措施来提高PLC的可靠性，最后在实验室和10kV现场进行了实验和测试。结果表明该系统具有投资费用少、可靠性高、安装维护简单等优点，在现场运行效果良好。
Abstract
According to the characteristics of the complex branches, the large number of monitored nodes and low requirement for real-time in medium voltage distribution network, Then a mode is proposed to realize distribution automation, that is communication means base on power line communication(PLC). The author introduces the communication structure in distribution network, Then hardware and software of PLC to the proposed mode are designed and accomplished. Main factors of effects on 10kV electric power carrier communication are analyzed, and then some corresponding anti-jamming methods including hardware and software are taken to improve the reliability of PLC. Finally, some experiments and tests are done both in the laboratory and the 10kV power line. Results showed that the PLC is in good operation. The communication system have the advantages of less investment, high reliability and simple installation and maintenance.
