【Title】The Multilevel Monitoring Technique for Time Synchronization

【摘要】本文阐述利用电力通信网建立电力系统省、地、站一体的多级时间同步监测系统的方法。该系统以省级区域内最高等级时钟源作为统一时源，利用现有的电力通信网以基于E1通道的精密时钟同步协议POE（PTP Over E1）方式实现各级监测装置的分级授时，保证整个监测系统的时源统一。各级监测装置通过直接采集时间信号、触发并监测时间顺序记录（SOE）报文、利用代理程序等方法实现对电力系统各级时间同步系统、二次设备、服务器和计算机等设备的时差测量，并将测量结果通过调度数据网逐级上送至各级监测管理系统，实现多级时间同步监测。

【Abstract】To create the multilevel monitoring system for time synchronization based on the power communication network, an approach is presented in this paper. To ensure every level’s time reference is coincident to each other, the system uses the highest level time reference as the unified time reference, and transfers the time reference by POE method on the power communication network. Each level’s monitor gets time deviations of time synchronization systems, IEDs, servers and computers through collecting timing signals, triggering and collecting SOE and using agent program. Then each level monitoring system sends the measured results to higher level monitoring system through the power communication network to process and the whole monitoring system is created and running.
