摘要
GOOSE(面向通用对象的变电站事件)是IEC61850标准中定义的用于解决智能电子设备(IED)之间互相通信的数据模型,GOOSE报文用于控制开关的跳闸或者合闸等关键信息,因此要求其具有很高的可靠性与实时性。目前在智能变电站中主要使用工业以太网交换机实现GOOSE报文的传输,文章介绍了一种用于工业以太网交换机的GOOSE报文优先转发方法,给出了具体的实施流程,并进行验证,实现了GOOSE报文在网络中的可靠快速传输,特别是在网络中存在大流量高优先级背景数据时,保证GOOSE报文无丢包且传输时延不受影响。
GOOSE（generic object-oriented substation event） is the data model that is defined in the IEC61850 standard for solving inter communication between intelligent electronic devices（IED）. For the usage of controlling key information of switch tripping or switch closing, GOOSE message requires fast and reliable transmission. Nowadays, industrial Ethernet switch is mainly used in intelligent substation for G（X）SE message transmission. It is significant to ensure fast and reliable transmission of GOOSE message in the case of large network traffic. The article provides a kind of G（X）SE message Expedited Forwarding for industrial Ethernet switches including specific implementation process and validation. It accomplishes the realization of fast and reliable transmission of CK）OSE message especially to ensure the transmis- sion of GOOSE message without packet loss and propagation delay in the situation of that networks in the presence of large flow and high pri- ority baekeround data.
