摘　　要：GOOSE是IEC61850对数字化变电站的重要贡献,其出发点是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实时性所作的规定,提出了全方位实现GOOSE实时性的观点,即在确保GOOSE服务正确可靠的前提下,在发送端、交换机和接收端分别采取措施尽可能地提高GOOSE报文的实时性。分析了在交换机提高GOOSE报文传输实时性、在接收端提高GOOSE报文处理实时性的原理。提出了GOOSE发送端多优先级发送队列的方法,解决了发送端GOOSE报文的延迟性和不确定性问题。GOOSE is an important contribution of IEC 61850 to digital substation.The aim of GOOSE is to realize the distributed substation automation functions.A point of view is advanced by analyzing the real-time communication of IEC 61850 GOOSE service mode ,that we should realize real-time GOOSE from all aspects including GOOSE sender,receiver and switch.The principle of enhancing GOOSE packet transmit speed on switch and enhancing GOOSE packet processing speed on receiver are analyzed. Multiple priority sending queues method on sender is advanced,which resolves the delay and uncertainty of GOOSE packet.
