Research Of 10kV Distribution Automation Based On PLC Communication

With the development of distribution automation technology, communication technology in distribution network operation and monitoring role in the field has become increasingly a cause for concern, the power line communications technology can make full use of existing physical network to exchange information advantages, so the development prospects is optimistic. 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 communicaton system have the advantages of less investment,high reliability and simple installation and maintenance.
