摘要
文章研究了简单网络管理协议(Simple Network Management Protocol,SNMP),结合与智能变电站中交换机的运行状态信息,设计了交换机状态监测系统,用于监测智能变电站中站控层和过程层交换机设备的实时运行状态;研制了隔离代理设备,实现了对过程层网络交换机的状态监测;对交换机网络拓扑关系进行了分析。该系统能够在线发现交换机运行状态变化,能使变电站运维人员及时消除设备故障,保障了变电站生产的安全。
This paper first studies the SNMP protocol and operation state of switch in smart substation, designs a switch state monitoring system to monitor real-time operation state of station control layer and process layer switch in smart substation. Then, isolation agent equipment is developed to monitor the state of process layer network switch. At last, the topology relationship of switch network is also analyzed in detail. The proposed system can detect switch state changing in time and help the maintenance employees troubleshoot equipment which can guarantee the safe production of substation.
