基于变电站配置文件的智能变电站交换机自动配置实现

针对变电站现场人工配置交换机虚拟局域网(VLAN)、组播等工作量大且容易出错的问题,提出了基于变电站配置(SCD)文件提取交换机配置信息以实现交换机自动配置的方案。在建立交换机模型和变电站物理连接关系模型的基础上,通过分析SCD文件中虚连接和物理拓扑连接的内在关联,利用数据库的连接和提取功能,匹配出交换机配置信息,并将配置信息保存成交换机配置(CSD)文件格式。将CSD文件下载到交换机,完成对交换机的统一离线配置,从而降低交换机的配置维护难度。实际证明该方法减少了现场配置工作量,在工程应用上有重要意义。

Implementation of Switch Automatic Configuration ofSmart Substation Based on SCD Files

Aiming at the problem that the workload of switch VLAN configuration and multicast is large and prone to error,a scheme of exchanging the switch configuration information based on the SCD file is proposed to realize the automatic configuration of the switch.Based on establishing switch model and physical connection model of substation,this scheme analyzes the inherent association between the virtual connection and physical topology connection and makes use of database''s function to match out switch''s configuration information,then output the configuration as CSD file.Downloading the CSD files into switch can complete switch''s unified off-line configuration consequently reducing switch''s configure and maintenance difficulty.It is proved that this method can reduce field configure work and is of great significance in engineering application.
