基于NTP协议的用电信息采集系统时间同步研究

用电信息采集系统在智能电网建设中所扮演的角色越来越重要,用电信息采集的准确性和高效性是建设智能用电体系的关键技术。为了提高用电信息采集系统的时间精度,提出一种经过网络不对称系数修正的NTP时间同步方法,分别采用客户/服务器模式和广播模式,自上而下对用电信息采集系统的采集终端和电能表进行时间同步,实现了精准同步。最后,研究了用电信息采集时间同步系统,有效提升了系统的用电信息采集准确性和高效性。

Research on power information collection system time synchronization based on NTP

The role of power information collection system in smart grid construction becoming more and more important, the accuracy and efficiency of the collection of power information is the key technology of building smart power utilization system. In order to improve the time accuracy of the power information collection system, this paper present an NTP time synchronization method based on asymmetric coefficient modification, using client/server mode and broadcast mode to synchronize the acquisition terminal and the meter of power information collection system from top to bottom respectively.Finaly, the time synchronization system of power information collection is studied, which effectively improves the accuracy and efficiency of power information collection system.
