摘　　要：面向通用对象的变电站事件(GOOSE)模型是IEC 61850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。通过分析VxWorks操作系统内核的特点,提出了基于VxWorks的IEC 61850 GOOSE发布的实现方案。GOOSE发布任务基于VxWorks事件组,采用事件驱动方式处理GOOSE初始发送、变化发送、快速重发和周期重发。给出了各GOOSE发送控制块共享的高精度定时器的使能和关闭方法。分析了VxWorks网络重发的实现原理,提出了新添加GOOSE协议的重发送实现方式。GOOSE is an important contribution of IEC 61850 to digital substations. The aim of GOOSE is to implement distributed substation automation functions. The realization plan for IEC 61850 GOOSE publisher based on VxWorks is advanced by making an in-depth analysis of the VxWorks kernel. The GOOSE publisher task is based on the VxWorks event group, with the event driver way used to send GOOSE messages including initial transmission, changed transmission, rapid retransmission, periodic retransmission. The method of enabling and disabling the high precision timer shared by all GOOSE publisher control blocks is given. The principle of implementation of the VxWorks network packet retransmission is treated and the way of realizing retransmission by incorporating a new GOOSE protocol in the network device is presented.
