摘　　要：根据数字化变电站继电保护的面向通用对象的变电站事件(GOOSE)需求,针对速动性分析了网络传输延时后提出了改进方法,并针对可靠性和安全性分别分析了不同冗余方式和交换机分配模式的特点。提出根据系统一次接线形式及继电保护配置特点合理规划继电保护GOOSE网络方案的方法,并给出了典型接线形式下的GOOSE网络方案。此外,应根据一次接线形式及继电保护配置特点对交换机虚拟局域网(VLAN)划分、优先级及多播报文过滤进行合理配置。Based on the GOOSE demand for the relay protection system in the digitized substation, the network latency is analyzed with respect to rapidity and methods for improvement are put forward. In connection with the reliability and security, the ways of redundancy and characteristics of the mode of switch assignment are analyzed, respectively. The method for rational design of the network scheme of the relay protection system according to the primary connection form and the characteristics of relay protection configuration is proposed. The GOOSE network schemes of typical connection forms are also demonstrated. Furthermore, the VLAN, priority and multicast filtering of switches should also be attended to in accordance with the primary connection form and the relay scheme.
