摘要
目前,国内大部分变电站系统网络与计算机设备缺乏安全准入监测功能,对于接入各层网络进行运维调试的设备以及系统内各台计算机上的U盘设备尚没有规范的管控手段。为了保障变电站网络及业务系统安全运行,遵照IEC61850规约,在分析智能变电站分层式结构的基础上,研发一种变电站安全准入系统,通过MMS协议实时上传网络设备及U盘拔插的监视信息至位于站控层的主站客户端。经过在南方电网公司的现场测试,该系统运行稳定符合预期,从源头上保证了变电站系统运行的安全性。
At present, network and computer equipment in most of the domestic substation system are lack of function for security access surveillance. There are not normative control means for operating and debugging computers accessed to every layer of net- work and U disk devices on each computer. In order to ensure the safe running of substation network and service system, a sub- station security access system is developed based on the analysis of smart substation layered structure according to IEC61850, which uploads real-time monitoring information of network equipment and U disk's insertion-extraction to master station client in control layer though the MMS protocol. After a spot test in China Southern Power Grid Company, the system runs stable as expec- ted, and which ensures the safety of substation system from the source.
