电力系统中稳定的时间同步系统研究

Study on Stable Time Synchronous System in Power System

针对电力系统中时间同步不稳定的问题,本文在分析常规时间同步系统的基础上,根据电力系统的特点,提出一种卫星授时与SDH同步的联合时间同步系统。该系统首先根据GPS授时精确测量经过SDH网络的主从时钟的不同延时值,然后利用测量的延时值补偿SDH网络造成的时间延时,提出一种稳定的时间同步系统。

According to the stability time synchronization of power system, the paper presents a stable time synchronous scheme of power system, based on the analysis of the current time synchronization scheme. The system uses the time of GPS to measure the different value of delay between the master clock and the slave clock, and then compensates the delay based on the measured value.
