变电站同步时钟对时系统的优化改造

Optimizing Transformation of Synchronous Clock Timing System of Substations

阐述了同步时钟对时系统在智能化变电站中的作用和要求,简要介绍了几种变电站常用对时方式,并结合其各自特点,通过案例分析,说明了变电站各系统时钟设备在提供统一基准时钟方面存在的缺陷,提出了优化改造方案。

The function and requirement of synchronous clock timing system in intelli-gent transformer substations are described. Some common time-setting methods for substations are introduced; and combining with the respective characteristics of these methods and through case analysis, some defects in the aspects of unified reference clock system provided by the clock devices of various systems in a substation are pointed out and an optimizing plan is proposed.
