| 详细分析了SNTP、IRIG-B、IEEE1588三种时钟同步方式的原理及特点,并总结了其优点和缺点。在研究了数字化变电站网络拓扑结构的基础上,按照站控层、间隔层和过程层分层讨论数字化变电站的时钟同步网络,结合三种时钟同步方式的特点,为新建变电站推荐时钟同步网络的建设方案,建议在站控层网络采用NTP协议,在过程层采用点对点连接方式时推荐采用IRIG-B,而组网的情况下建议采用IEEE1588,并建议过程层推广应用IEEE1588时钟同步协议。 |
| 英文摘要: |
| This paper describes in detail the principles and characteristics of three types of clock synchronization schemes, namely SNTP, IRIG-B and IEEE1588, and summarizes their advantages and disadvantages. Based on a study of the network topology structure at digital substations, it discusses clock synchronization networks at digital substations for the station level, bay level and process level, and under consideration of the characteristics of these three types of clock synchronization schemes, it recommends application of the clock synchronization scheme to the construction of new substations, whereby the station level should use the NTP protocol, and the process level should use IRIG-B in the case of point-to-point connection or IEEE1588 in the case of network construction. It is further proposed that the process level should use IEEE1588 clock synchronization protocol. |
