ABSTRACT: Jane harmonic detection technology is an important content of power system harmonic governance, the paper proposes an improved ITD method combined with singular value difference spectrum of fast high precision detection. By improving the ITD method it can directly according to measured data with feature information contain system parameter identification. First, using singular value different spectrum system order, and then using ITD improved directly on the noise signal accurately detect the actual frequency of each harmonic, using the ...
