摘要
随着智能变电站的推广应用,变电站对标准时间同步系统的要求越来越高,本系统采用FPGA搭建的时间同步系统,实现了GPS、北斗和IRIG-B等多种时钟源输入冗余技术和锁相环技术,输出电站时间同步需要的脉冲、串口、IRIG-B、NTP、PTP和光纤编码等信号。
With the popularization and application of intelligent substation,substation on the standard time synchronization system have become increasingly demanding,the system uses the construction of time synchronization system FPGA to achieve a GPS,BD and IRIG-B input redundancy technical and frequency PLL,the output of the substation needs time synchronization pulse,serial,IRIG-B,NTP,PTP and optical coding signal.
