摘　　要：为解决面向通用对象的变电站事件(Generic Object Oriented Substation Event,GOOSE)虚端子在变电站扩建、改建时,无法满足场景需求的问题,提出基于采样值(Sampled Value,SV)与实时持续性通信的GOOSE虚端子快速化验证方法。通过分析SV虚端子以及GOOSE虚端子的变电站过程层虚端子连接类型,选取SV和GOOSE共口传输的实时持续性通信方案。利用以太网控制器,实现变电站过程层内SV报文和GOOSE报文共口传输的实时持续性通信。利用所提的通信方案,对变电站配置的描述文件实施标准化验证,通过发送方配置验证、接收方配置验证以及通信配置验证的三方共同验证,实现GOOSE虚端子的快速化验证。实验结果表明,所提方法产生的通信时延均低于8 ms,具有良好的通信性能,可以快速化验证GOOSE虚端子,缩短变电站装置现场调试时间,满足变电站应用场景需求。In order to solve the problem that Generic Object Oriented Substation Event(GOOSE)virtual terminals cannot meet the scene requirements during substation expansion and reconstruction,this article proposes a rapid verification method for GOOSE virtual terminals based on Sampled Value(SV)and real-time continuous communication.By analyzing the connection types of SV virtual terminals and GOOSE virtual terminals in the substation process layer,a real-time continuous communication scheme for SV and GOOSE shared port transmission is selected.Using an Ethernet controller,real-time continuous communication between SV messages and GOOSE messages is completed,and real-time continuous communication between SV messages and GOOSE messages in the process layer of the substation is realized.Using the communication scheme proposed in the article,standardized verification of the substation configuration description file is implemented.Through the joint verification of the sender configuration verification,the receiver configuration verification,and the communication configuration verification,rapid verification of GOOSE virtual terminals is achieved.The experimental results show that the communication delay generated by the proposed method is less than 8 ms,and has good communication performance.It can quickly verify GOOSE virtual terminals,shorten the on-site debugging time of substation devices,and meet the requirements of substation application scenarios.
