摘　　要：针对卫星信号受环境影响时,会出现授时系统可靠性不够高、安全性差等问题,在原卫星授时系统的基础上,加入IRIG-B时间码作为第3种外部时钟源,通过多模高精度授时算法和驯服守时技术,得到高精度时间同步。实验结果证明该电力时间同步装置能够满足设备的应用需求,可以明显提高授时的可靠性与安全性。Aiming at the problem that it is liable to low reliability and poor security of the timing service when the satellite signals are affected by the environment, the paper proposed to add IRIG B time code as the third external clock source and obrain the high precise time synchronization by multirnode high precise timing service algorithm and disciplining holdover teehnology. Experimental result showed that the studied time synchronization device of electric power could meet the application requirements of the equipment and improve the reliability and security of the timing service obviously.
