摘要
为解决智能变电站过程层网络装置过分依赖对时网络问题,及智能变电站过程层网络SMV报文间、SMV和GOOSE报文间及GOOSE报文间的相互干扰问题,提出了通过在交换机上实现延时可测技术和业务流量管理技术有效解决过程层网络现存的两个主要问题。延时可测技术通过GOOSE、SMV报文携带经过交换机的延时值实现时间同步。业务流量管理技术通过基于目标MAC地址的流量控制方法解决过程层网络报文间相互干扰问题。
This paper aims to solve the problems of intelligent substation process layer network devices over relying on the synchronous network, and the mutual interference between two SMV packets, between SVM and GOOSE packets as well as between two GOOSE packets. Through realizing delay measured technology and business traffic management technology, two major problems existing process layer network are effectively solved. Delay measure technique realizes time synchronization by using the delay value carried by GOOSE, SMV packets through switch. Traffic management technology is used to solve the problem of mutual interference of process level network packets through the flow control method of destination MAC address.
