摘要(Abstract)：
合并单元是数字化变电站数字接口的核心功能单元,涉及变电站内甚至变电站间多种设备,是保证各类数据准确可靠的关键。在介绍合并单元主要功能的基础上,分析了合并单元同步方法,从同步误差、采样准确性等方面系统阐述了合并单元的模拟和数字检测两种方法。
Merging units,which involve a variety of equipments in substations and between substations,are the core function units of digital interface in digital substations and also the key to ensuring the accuracy and reliability of various data.This paper introduces the main functions of merging units.Through the analysis on synchronization methods,it elaborates two methods of simulation and digital test systematically in terms of synchronization errors,sampling accuracy etc.
