为了提高变电站二次系统的设计与管理水平,研究了基于IEC 61850标准的数字化变电站二次系统精细化管理模型.信息流与镜像逻辑节点、合理通信网络、保护实现方式等影响着系统的运行,成为精细化管理的对象.文中设计了相关数据库,对信息流、虚拟输入/输出量、网络拓扑连接、虚拟局域网(VLAN)与多播组、镜像节点等进行信息管理.以某实际变电站为例进行了系统与网络的规划设计,对多种功能应用进行分析,提出了实现精细化管理的建议,是对变电站二次系统设计的有益补充与完善.

To improve the design and managing level of the digital substation secondary system, a refined management model for digital substation secondary system based on IEC61850 is studied. As the configuration information flows between intelligent electronic devices (IEDs) and the mirror logical nodes, the rational communication network and protection implementing modes influence the system operation, they have become refined management objects. The relevant database is designed to carry out refined management of the information flows, virtual input/output variables, network topological connection, Virtual local area network(VLAN) and muhicast group, mirror logical nodes. The planning and design of an actual substation system and network is given and an analysis is made of the multiple function application, providing suggestions for digital substation design and configuration.
