Abstract

Along with the diversification and complication development of electric equipment in warship, the harmonic pollution in power system is more and more seriously, and the harmonic detection technology increasingly turns into a very important subject. FFT arithmetic is an usual method to detect harmonic component, but this method is often accompanied with spectrum leakage and fence effect which can bring measurement error. The article analyses spectrum character of different window functions, compares merits of different interpolation methods, and then improves FFT arithmetic and defines detection index. The experiment proves that the improved method gets better result on detecting harmonic signal which fundamental frequency is 49.8Hz-50.2Hz.
