摘要:
为解决智能变电站现场站域测试时无线分布式数据的时间同步问题，提出了一种适用于无线数据通信的多终端同步控制策略。介绍了智能变电站的站域测试系统及其实现的关键性问题，说明了网络传输延时不确定对IEEE 1588网络时钟同步协议的影响，研究了基于单点对多点无线通信系统同步的样本滤波、同步校正、时域跟随等问题，并给出了实施方案。实验结果表明，无线通信下经同步控制后时间精度可达微秒级，能够满足智能变电站系统级测试对时间同步的需求。

Abstract:
In order to solve the time synchronization problem of wireless distributed data in the field test of intelligent substation, this paper proposes a multi terminal synchronization control strategy for wireless data communication. It introduces the substation area test for the intelligent substation and its key problems, describes the influence of the uncertain network transmission delay time on the IEEE 1588 network clock synchronization protocol, researches the sample filtering, synchronous correction, time domain following and other issues that based on the single point to multipoint wireless communication system synchronization, and gives the implementation scheme. Experiments show that the synchronization precision with this synchronous control in the wireless communication can reach microsecond, which can meet the synchronization demand of the intelligent substation system-level test.
Key words:  intelligent substation  substation area  test  wireless communication  IEEE 1588  synchronization
