Shengmin Li · Electrical Measurement & Instrumentation · 2012
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.
