摘要
介绍了目前智能变电站主要采用的脉冲对时、串口对时、SNTP、IRIG-B及IEC61588等对时技术。由于变电站结构配置不同,通常采用多种对时技术方式,分析了基于IEC61588的智能变电站时钟同步方案。针对智能变电站网络化对时系统技术特点及组网模式等进行分析,比较了传统变电站与智能变电站同步对时系统的优缺点。
This paper introduces the different network synchronization of present smart substations, such as impulse synchronization, serial synchronization, SNTP, IRIG- B as well as IEC61588, etc. Due to the various substation infrastructure configurations, mul- tiple synchronization techniques are applied and the time synchronization system based on IEC 61588 in smart substation is analized. The technical feature and network modes of Network synchronization system in smart substation are discussed. A comparion between the clock synchronization systems of conventional substations and in smart substations is also made in this paper.
