摘要: |
智能变电站通信网络承载着采样值和保护跳闸等重要信号,网络交换机是信息可靠传输的关键。对网络交换机进行信息建模是实施IED化管理的前提。介绍了IEC 61850通信体系架构和IED功能服务建模步骤。在分析智能变电站网络交换机功能的基础上,研究了网络交换机的信息模型,重点列举了逻辑节点零、端口管理、流量统计和告警管理的逻辑节点类模型。然后探讨了网络交换机的服务模型和通信服务映射实现方法,并展示了交换机的变电站配置描述语言(SCL)示例。最后给出了网络交换机信息建模在智能变电站的应用实例。 |

Abstract: |
Communication networks in Smart Substation carry the sampling value and the protection trip signal, and the Ethernet Switch is the key to the reliable transmission of information. Information modeling is the premise of managing Ethernet switches as an IED. Firstly, the IEC61850 communication system architecture and the IED function and service modeling steps are introduced. On the basis of analyzing Ethernet switches function in smart substations, the information model of Ethernet switches is researched, focusing on the logical node class model of the logical node zero, port management, traffic statistics and alarm management. Secondly, the service model of Ethernet switches and communication service mapping are discussed, and the example of switches with substation configuration description language (SCL) is demonstrated. Finally, an application instance of Ethernet switches with information model in smart substation is given. |
