Application of Portable Power Grid Harmonic Wave Detection Device in Power System

The quality of electric energy has much to do with the stable operation of power systems.The measurement and analysis of power quality and the reliability of these devices play a crucial role in the detection of power grid harmonic wave.Wavelet transform theory is adopted in the detection and analysis of power grid harmonic wave on the basis of embedded linux operating system and GUI graphical interface with S3C2410 as the core for the research and design of the harmonic detection device.
