综合电能质量在线监测仪系统设计

摘要

针对目前电网数字化变电站和传统变电站并存的实际情况,本文介绍了一款基于嵌入式平台的新型电能质量在线监测仪设计方案.系统采用模块化设计,包括合并单元采集、传统互感器电压电流信号采集、DSP数字信号处理和ARM处理平台四部分.通过DSP和ARM的有效结合,系统完成合并单元、传统互感器电压电流采集、计算、显示和存储工作.该方案及兼顾传统的变电站和数字化变电站,有较好的市场实用价值.%According to the real situation of digital transformer substation and traditional transformer substation,this paper introduces an new online power quality monitor which isbased on embedded platform.This system adopts modularization design which includes merging unit signal collecting,traditional instrument transformer signal collecting,DSP signal processing and ARM processing platform.This system can collect,count,display and store plant operation data since combination of DSP and ARM.This solution is useful for the power quality monitor in the digital substation and the traditional substation.
