| 摘 要： | 在介绍数字化变电站系统基本结构和组网方案的基础上,通过对报文传输的测试,提出数字化变电站过程层组网方案.星形结构在运行维护、传输时间等多方面优于总线型、环形结构,宜采用双星形结构构建过程层网络.在不同的交换机数据传输流量下对采样值和保护跳闸命令2类最重要的报文传输进了测试,结果表明:交换机数据流量大时,会造成采样值变化...

| Abstract: | The basic structure and networking schemes of digital substation are introduced,and some networking schemes are proposed for the process level of digital substation based on the message transmission tests.As star structure is superior over bus and ring structures in operational maintenance,transmission time and so on,dual-star structure is proposed for process level networking.The transmission of sampling value message and protection trip message is tested under different conditions of switch data flow.Resu... |
