摘　　要：对IEEE 802.11ac的几种工作模式配置进行了测试,并与常用的电缆连接进行比较。将GPS仪器与IEEE 1588时钟同步化结合使用。结果表明,在流量负载为80 Mb/s的IEEE 802.11ac无线链路上,面向通用对象的变电站事件发布方和用户之间的IEC 61850传递时间的平均值和最大值分别为5.4 ms和10 ms。在网络流量负载不大的情况下,测试的IEEE 802.11ac链路能够满足IEC 61850的应用要求。To study the application of wireless communication in smart grid automation,the connection deployment and characteristics of IEEE 802.11ac between IEC61850 electrical automation devices were designed and analyzed.Several working mode configurations of some IEEE 802.11ac were tested and compared with common cable connections.In order to obtain meaningful results and reduce measurement uncertainty,GPS instrument and IEEE 1588 clock synchronization were combined.The experimental results show that on the 802.11ac wireless link with 80 Mb/s traffic load,the average and maximum transfer time of IEC 61850 between the publisher and user of GOOSE are 5.4 ms and 10 ms,respectively.Therefore,the tested IEC 802.11ac link can meet the application requirements of IEC 61850 when the network traffic load is small.
