Study on the Time Synchronization System in Coal Mine Grid
Zhi Jie Wang, Yan Wen Wang · Advanced materials research · 2013
The paper first introduces the importance of the time synchronization system in the coal mine power supply system and the common reference clock sources, which are GPS and Beidou system. Then, it analyzes the characteristics of the common working modes of time synchronization system. Finally, the time synchronization system in coal mine gird based on host/standby mode and spare each other mode is proposed, which provides significance for the implementation of such technology in coal mine power supply system.
