摘要
基于直流电源运行、维护现状分析,提出了一种基于电力局域网的直流电源远程监控及维护系统,给出了该系统的拓扑结构,规划了系统的总体功能。将计算机技术、自动化技术和光纤局域网通讯技术应用于该直流系统,通过光纤网络将分散的直流电源运行参数和系统状态传送到数据中心服务器和远程终端进行实时监控,同时实现了蓄电池的在线均衡和远程核对性放电维护,提高了变电站直流系统的自动化管理水平。
According to the current situation of operation and maintenance of DC power resources, a remote monitoring and maintenance system based on power system LAN is proposed. And the topological structure and general function of the system are presented. Then the computer technique, automation and optical LAN communication technology is ap- plied to IDC power system. Finally, the decentralized parameters of DC power resources are sent to data central server and remote terminal for real-time monitoring. Moreover, online equilibrium of storage batteries and remote check discharging are realized. Therefore, it raises automation management level of DC system in substations.
