摘　　要：在城市配电网中,配电自动化对通信提出较高的要求,使用载波通信技术能有效满足数据传输的需要,并节约大量通信基础建设成本。通过研究环网电缆载波链路,载波通信自由路由调度可利用10 kV环网物理成环的特点,经配电自动化平台与载波通信管理设备协同操作,实现载波通信路由的自动切换,切实有效地提高配网载波通信的可靠性。通过在10 kV配网现场应用试验,证明电缆环网载波通信的自由路由调度方法能为配电自动化提供稳定的通信保障。In the city distribution network, distribution automation has very high requirement for communication. The use of PLC communication technology can effectively meet the needs of data transmission, and significantly save communication infrastructure costs. Through the study on the PLC link of cable ring, PLC free routing schedule can make use of the characteristics of 10 kV cable ring structure to achieve the PLC automatic route switch and to effectively improve the reliability of PLC communication for distribution network, while co-operating with the distribution automation platform and the PLC communications management system. The field tests on the 10 kV distribution network prove that the PLC free routing schedule is able to provide a stable communication support for distribution automation.
