Digital Filter Design in Power’s Harmonic Wave Detection

Article Preview

Abstract:

Pollution harness of industry power mainly depends on high-accuracy harmonic signal detection. In this paper digital filtering technology and instantaneous reactive power theory are used to detect power harmonic signal and the main motive is to reduce the computation amount. A low-pass filter with Butterworth style is designed and its effectiveness to detect the second-order harmonic wave is shown by numerical simulation.
