摘要:
分析了IEC61850标准中保证面向通用对象的变电站事件(GOOSE)服务具备实时应用特征的相关协议规范。数字化变电站内部主要通信报文为基于客户/服务器模式的MMS报文、GOOSE报文和采样报文。讨论了主要通信报文的应用特点;基于GOOSE网络通信的安全性、可靠性、实时性,讨论了在数字化变电站发展过程中,从独立组网至全站共网的各种组网方式以及装置单环网、星形网等网络结构在GOOSE组网应用中的优缺点,分析了VLAN技术、报文优先级、链路聚合等网络技术在GOOSE组网过程中的应用。最后结合具体实例对GOOSE组网方式、组网结构以及交换机的配置进行分析研究。

Abstract:
The protocols in IEC61850 standard to ensure the real-time performance of GOOSE service are analyzed. The internal communication messages of digital substation are mainly MMS messages,GOOSE messages and sampling messages,and their application features are analyzed. Based on the security,reliability and real-time performance of GOOSE network,the development of networking mode from special network to common network in digital substation is discussed and the application features of single loop-type and star -type network structures in GOOSE networking are explained. Applications of VLAN technology,message priority technology and link aggregation technology in GOOSE networking are studied. Case study is provided for GOOSE networking mode,network structure and switch configuration.
Key words:  IEC61850  GOOSE  digital substation  switch  network technique
