基于全相位FFT算法的電力諧波檢測方法
楊宇祥,樊巨寶*

(西安理工大學 機械與精密儀器工程學院,西安市,710048)

摘要:諧波檢測是電力系統諧波污染防治的關鍵。傳統的基于加窗FFT諧波分析方法受非同步采樣和信號截斷的影響而出現較大的頻譜泄露。全相位FFT綜合考慮了數據中所有截斷情況,因而具有優良的頻譜泄露抑制性能和相位不變性。本文提出基于全相位時移相位差法的諧波檢測方法,并對電力諧波進行了仿真實驗。仿真結果表明:全相位時移相位差法能夠精確提取出諧波信號中各次諧波的頻率、幅值和相位信息,精度可達到小數點后第7位, 遠好于傳統的加窗FFT方法。本方法為進一步提升電力諧波檢測的精度奠定了理論基礎。
關鍵詞:電力諧波檢測;全相位FFT;時移相位差法

A new power harmonic detection method based on all-phase
FFT Algorithm
YANG Yuxiang, FAN Jubao
(Xi'an University of Technology, Faculty of Mechanical and Precision Instrumentation Engineering, Xi'an 710048)
Abstract: Harmonic detection is the key technology of electric power system harmonic pollution
detection and prevention. Affected by signal asynchronous sampling and truncated effect, the traditional harmonic analysis method based on windowed FFT algorithm occurs large spectral leakage. The all-phase FFT algorithm, comprehensively considering every truncated situation in data, has excellent performance on leakage suppressing and the characteristic of phase invariance. This paper proposes a new harmonic detection method based on the all-phase time-shifting phase
difference correcting algorithm, and the simulation experiments with electric power harmonic are performed. The simulation results show that the proposed algorithm can extract accurately the signal frequencies, amplitudes and phases of every harmonic. The precision reaches 7 decimal places, whick is far better than the traditional windowed FFT algorithm. The proposed method lays a theoretical foundation for further improving the precision of power harmonic detection.
