摘　　要：随着配电网技术的发展,配电网络的保护问题变得尤为突出,对其保护性能的要求也逐步提高。随着分布式发电的逐步普及、网状拓扑结构的应用以及电力用户消费者需求的不断提高,需要提供更加智能的保护机制。在基于IEC 61850协议的基础上对变电站内通信进行扩展,将其概念扩展到变电站之间的通信,即配电网通信。文章详细介绍了故障通道继电保护和电流差动继电保护两项技术,作为配电网馈线自动化和网络通信保护,并在原有的基础上创新地提出了两种保护技术用于配电网通信保护的保护方案。With the development of distribution network technology,protecting the electricity distribution networks is becoming increasingly challenging and requirement of the protection performance is continually being increased. The popularization of the distributed generation,the application of the network topology structure,and the service demands of consumers require smarter protection. This paper describes the findings of an investigation into extending the concepts of communications within the substation contained in IEC61850 beyond the substation in order to provide substation to substation communications. As the protection of distribution feeder automation and an associated internet communications,this paper describes the technology of fault passage protection and current differential protection in detail,and on the original basis,it proposes the protection scheme which applies them into the protection of distribution network communication.
