NKE-90 satellite time synchronization clock system
Clock source PPS and IRIG-B time signal of NKE-90 satellite GPS/ receiving time synchronization of master clock Beidou / satellite, signal can be TTL level, RS485 level or the empty node mode. NKE-90 will be on the received signal into optical signal multipath parallel optical fiber, through precise absolute time stamp to send intelligent device layer and process layer to the quantity of fiber channel, time can be flexibly configured according to the requirements of engineering. When the GPS/ Beidou / satellite clock source is abnormal or not configured GPS/ Beidou / satellite clock source under the condition of NKE-90, according to its own clock source sends out the high precision relative timing signal, time accuracy is better than 1 s.
NKE-90 to the total of all intelligent device synchronization, including: protection device, control device, automatic safety device, electronic transformer and intelligent switch, compared with the traditional transformer substation, it makes all intelligent device for synchronous operation, the realization of the intelligent device interaction, to provide support for the system and wide area control and wide area measurement station domain control
NKE-90卫星同步对时时钟系统
NKE-90卫星同步对时主时钟接收GPS/北斗/卫星时钟源的PPS和IRIG-B对时信号，信号可以是TTL电平、RS485电平或空节点模式。NKE-90将接收到的对时信号转化为多路并行的光信号，通过光纤将精确的绝对时标发送给间隔层和过程层的智能装置，光纤对时通道的数量可根据工程需求灵活配置。当GPS/北斗/卫星时钟源出现异常或不配置GPS/北斗/卫星时钟源的情况下，NKE-90依据自身的时钟源向外发送高精度的相对时标信号，时间准确度优于1μs。
NKE-90给全站所有智能装置对时，包括：保护装置、测控装置、安全自动装置、电子式互感器和智能开关等，与传统变电站相比，它使所有智能装置同步运行，实现各智能装置协同互动，为站域控制、广域控制和广域测量提供支持
