Development of Power Quality Analysis Device Based on ARM and DSP
Firstly,the power quality detection device combining DSP and ARM is designed.After that,it mainly completes the design of signal acquisition,signal conditioning and other detection circuit functions;Then,the software design of the device is car-ried out,mainly completing the design of DSP and ARM main programs,using wavelet packet transform and fast Fourier transform to process the sampled data,then using LabVIEW software to make a simulation program,and finally completing the detection perform-ance test of the device on the built experimental platform.The experimental results show that the error of the device is about 1％,and the design has achieved the expected effect.
