Abstract

Reduced frequency resolution and spectral leakage are the two major defects on the Fourier spectrum resulting from a data window function and fast Fourier transform (FFT) in power system harmonic measurement. In this paper a novel method, termed the integer periodic extension (IPE) method, is proposed to overcome the noted problems. The proposed method simplifies measurement process and increases measurement accuracy. Finally, five cases from practical demand-side power systems are demonstrated with improved performance.
