摘要

阐述了IEEE 1588协议比以往时间同步方式如网络时间协议（NTP）的优点，分析了IEEE 1588协议的2个核心算法———最佳主时钟（BMC）算法和本地时钟同步（LCS）算法，提出了解决IEEE 1588协议在实际应用中不能满足其假设前提的解决方法，在实验室环境中利用ARM9200平台实现了IEEE 1588协议并进行了测试，结果表明其明显优于NTP。该研究工作对于IEEE 1588协议在电力系统中的实际应用具有重要意义。

Abstract

The IEEE standard precision time protocol（PTP） IEEE 1588 is at present a very comprehensive solution for highly precise time synchronization in an Ethernet network for its many advantages over the traditional power station time synchronization protocol， such as the network time protocol（NTP）. The core algorithms of the IEEE 1588， the best master clock（BMC） algorithm and the local clock synchronization（LCS） algorithm， are analyzed. A solution is proposed for the situation in which the protocol is incapable of meeting its assumptions in actual application. The protocol is finally realized and tested based on an ARM9200 platform in laboratory surroundings， with evidently better accuracy than NTP. The research is of great significance for actual power system application.
