Research on a Method of Clock Synchronization of Power Users' Power Information Acquisition Terminal Based on a New Timing Algorithm

摘要

In order to solve the problem that the accuracy of time synchronization in power consumption information collection system is insufficient, a method of clock synchronization of power users' power information acquisition terminal based on a new timing algorithm is proposed. This paper first analyzes the traditional NTP time synchronization algorithm. In view of the shortcomings of the algorithm in clock synchronization, the channel asymmetry is fully considered and the algorithm is optimized in this paper. Also, a synchronization calculation method based on minimal round trip difference of NTP is proposed. By implementing this method in the synchronized structure of electricity info-collecting acquisition terminal clock, it can be seen that the new synchronization calculation method is largely improved in both accuracy and convergence compared with older one.
