摘要

智能变电站中合并单元的采样同步直接影响测控与保护设备的可靠性。文中从合并单元的相关技术需求和实际问题出发，提出了一种严格保证等间隔采样控制与同步的优化方法，此方法通过实时测量同步误差来修正同步采样周期。在首先保证采样周期均匀等分的基础上，动态地补偿本地采样时刻的偏差，实现每个采样时刻的精确控制与同步。测试结果表明所提方法使合并单元可靠地实现了采样同步。

Abstract

The quality of sampling synchronization in the merging unit directly influences the reliability of supervision and protection equipments in a smart substation.According to the correlative technical demand and actual problems of the merging unit，an optimization method which strictly ensures equal-interval sampling control and synchronization is proposed.This method corrects synchronous sampling cycle by measuring the synchronization error in real time，and dynamically compensates for the deviation of local sampling moment based on ensured well-distributed and equal sampling cycle to realize precise sampling moment and synchronization.The test results of sampling synchronization performance show that equal-interval sampling synchronization in the merging unit can be reliably implemented using this technology.
