摘　　要：随着我国通信技术的飞速发展,变电站综合通信网络系统已经初步代替了传统二次电路,而变电站综合自动化控制系统也体现了二次电路网络系统在发展过程中的高度智能水平和特性。不过,很多地方电力公司还是采用了传统的检查方式来检测和保养设施,仅通过网络消息来分析变电站设施的互联问题,对于智能变电站是不够的。要改善继电保护设备的使用安全,就需要对其进行实时监控,以便对其进行实时的故障诊断与处理,保证其正常工作。With the rapid development of communication technology in China, the substation integrated communication network system has initially replaced the traditional secondary circuit. The substation integrated automation control system also reflects the high intelligence level and characteristics of the secondary circuit network system in the development process. However, many local power companies still use traditional inspection methods to detect and maintain facilities. They only analyze the interconnection problem of substation facilities through network messages, which is not enough for intelligent substations. In order to improve the safety of relay protection equipment, it is necessary to monitor it in real time so as to diagnose and deal with its faults in real time and ensure its normal operation.
