The Design and Implementation of Power Harmonic Analysis System Based on Wavelet Packet Transform and ARM Platform

摘要：

In this paper, the design of a real-time harmonic analysis and measurement system is proposed, the system is combined by the ARM and virtual instrument technology, the wavelet packet transform is used to detect harmonic, also, the paper set out the systems hardware structure diagram, harmonic analysis algorithm, the simulation result, and the LabVIEW subroutine which used to show the result. As a result, it proved that the system can improve the timefrequency resolution obviously and track the changes of all harmonics on real-time by using wavelet packet transform.The system increased the feasibility of monitoring the harmonics.
