摘要

电子式电流/电压互感器已成为变电站自动化系统中十分重要的组成部分。笔者提出了一种利用FPGA上的嵌入式处理器实现合并单元的方法

它利用了MicroBlaze处理器内核

并且使用知识产权内核（IP）来实现各功能模块

完成了合并单元同步、多路数据接收和处理以及以太网通讯等功能

满足了电子式互感器数字接口高速、实时、可靠的要求。实验结果表明

该设计基本满足IEC 60044和IEC 61850对合并单元的要求。

Abstract

Because the ECT/EVT has become one of the most important parts of automation system in substation

a scheme using embedded processor on FPGA was proposed to implement merging unit.The MicroBlaze provided by Xilinx was adopted as embedded processor

and the functional modules were implemented using intellectual property core to satisfy the functions of merging unit synchronization

multi-channels acquisition

and Ethernet communication.This method can fulfill the requirements of high-speed

real-time and reliability for electronic transducer.Test results show that this scheme basically satisfy the requirements of IEC 60044 and IEC 61850 for merging unit.
