摘要
时间同步系统作为智能化水电厂基础支撑系统,在智能化水电厂建设中发挥着基础服务作用。主要介绍了白山发电厂建设对时系统的结构及主要特点,首次采用PTP授时作为备用信号输入,增加了整个时钟系统的稳定性,提高了系统的授时精度,实现远程异地授时。
As the fundamental support system for intellectualized hydraulic power plant,the time synchronism system offers basic service in construction of intellectualized hydraulic power plant.The paper introduces structure and chief characteristics of clock calibration system in Baishan Power Plant,which using PTP time transfer as the standby signal for the first time,that improving stability and accuracy of clock system and realizing the remote time transfer.
