摘要
基于数字化变电站的发展要求,分析了数字化变电站数据共享的需求,设计了数字化变电站需要的同步时钟源,分析了同步时钟的实现方案及其差异,介绍了采用现场可编程门阵列(FPGA)芯片实现时钟同步的方案。
Based on the requirement for digital substation development, the digital substation data sharing demand is analyzed, its need for the synchronized clock source designed, and the implementation scheme for the synchroclocks and the difference among them discussed. Finally, a plan for the rational solution with the field programmable gate array （FPGA） is proposed.
