It is discussed that the present harmonic analyzers do n ' t satisfy the requirements of china standard for harmonic measure of quick disturbance harmonic load. the measurement error brought about by the harmonic analyzers adopting ft or fft algorithm is analyzed. a cycle discrete fourier algorithm that should n ' t be effected by aperiodic component is presented, and the results of simulation show that it has higher accureacy
本文對電力系統諧波的測量方法,數據處理及電力牽引負荷對電力系統的影響進行了研究,論述了目前國內外生產的諧波分析儀用於快速波動諧波負荷的測量不滿足國標的要求,分析了諧波分析儀普遍採用的ft或fft演算法所產生的測量誤差,提出了一種不受非周期分量影響的全周波離散傅里葉演算法,模擬結果表明精度好。
