换流站时钟及服务器对时异常故障分析

针对银川东换流站主时钟及服务器对时异常问题,通过对主时钟和服务器对时工作原理进行分析,提出了主时钟增加装置容错机制及内部时钟守时机制,服务器系统增加对时抗干扰机制的解决方案。应用结果表明:该方案有效提升了主时钟及服务器抗外部信号干扰的能力,大大提高了站内设备运行的稳定性。

Fault analysis on GPS time synchronization abnormality of the master clock and server inconverter station

Aiming at the problem of time setting abnormality of the master clock and server inYinchuan Eastern Converter Station, By analyzing the GPS time synchronization principle of themaster clock and server, puts forward the solution scheme that to add device fault-tolerant mechanismand internal clock punctuality mechanism for the master clock, to add time setting anti- interferencemechanism for server system. The application result shows that the scheme effectively improves theanti-interference capability of the external signal for the the master clock and server, at the same timeimproves the stability of the equipments operation in the converter station.
