摘　　要：为了有效部署变电站自动化系统,一个安全、可靠、有弹性、标准化和可互操作的通信架构必不可少。目前,软件定义网络(SDN)技术正越来越多地应用于智能电网领域。将SDN技术应用于变电站自动化系统中,对时间关键型通用面向对象变电站事件(GOOSE)报文进行优先级排序,以减少其在网络中的延迟,进而提高变电站自动化系统的可靠性和服务质量(QoS)。在虚拟SDN环境中演示了所开发的优先级排序方法,通过开发虚拟租户网络(VTN),对提出的GOOSE优先级算法在基于SDN的变电站自动化系统中的性能进行了评估。结果表明,提出方法可以为GOOSE报文提供较低的传输延迟,从而实现变电站系统的自动化。In order to effectively deploy substation automation systems,a secure,reliable,resilient,standardized,and interoperable communication architecture is essential.Currently,Software Defined Network(SDN)technology is increasingly being applied in the field of smart grids.This article applies SDN technology to the substation automation system,prioritizing time-critical General Object Oriented Substation Event(GOOSE)messages to reduce their latency in the network,thereby improving the reliability and Quality of Service(QoS)of the substation automation system.This article demonstrates the developed priority ranking method in a virtual SDN environment,and evaluates the performance of the proposed GOOSE priority algorithm in a substation automation system based on SDN by developing a Virtual Tenant Network(VTN).The results indicate that the proposed method can provide lower transmission delay for GOOSE messages,thereby achieving automation of the substation system.
