| 摘 要： | 通用面向对象的变电站事件(GOOSE)服务模型主要用于数字化变电站自动化功能的分布式实现.通过深入分析IEC61850标准针对GOOSE通信实时性所作的规定,提出了在发送端、交换机和接收端全方位实现GOOSE报文传输实时性的方法.在交换机根据虚拟局域网(VLAN)和报文优先级提高GOOSE报文的传输实时性,在接收端根据任务优先级提高GOOSE报文处理实时性.提出了G00SE报文发送端多优先级发送队列的方法,在网卡驱动中根据报文优先级设计不同的待发送队列,优先发送高优先级的报文,从而解决了发送端GOOSE报文的延迟性和不确定性问题.

| Abstract: | GOOSE(Generic Object Oriented Substation Event) service model is mainly utilized to realize dis- tributed substation automation functions.Based on the analysis of the real-time communication for GOOSE service stipulated in IEC61850,an overall realization approach is presented for GOOSE sender,receiver and exchanger.The GOOSE packet transmission speed of exchanger is enhanced based on VLAN and packet priority,and that of receiver is enhanced based on task priority.The method of multiple priority sending queu... |
