随着智能电网的发展,对时间同步提出了更高的要求。IEEE1588时钟同步协议能够满足智能电网对时间同步的苛刻要求,具有极大的发展潜力。简要概述了目前智能电网时钟同步存在的问题,提出了高精度卫星同步时钟和基于IEEE 1588协议的智能电网时间统一技术的技术方案。
With the development of smart grid,higher requirements on synchronous clock are put forward. The time syn-chronization requirements in smart grid can be satisfied by IEEE1588 clock synchronization protocol. A brief overview of the existing problems on synchronous clock in smart grid is provided in this paper, the technology scheme of high preci- sion satellite synchronous clock and time unification technology in smart grid based on IEEE 1588 protocol is proposed.
