频谱细化在电力谐波分析仪中的应用
Application of a Power Harmonic Analyzer Based on Zoom-FFT
摘要
Abstract
This paper presents a spectrum zoom based on two-section FFT algorithm,uses the storage space which stored the data of the previous calculation,increases the actual calculation of the length of the data,but the computation time increasing no much,improves FFT frequency resolution.Using the powerful digital signal processing capability of the DSP chip on the harmonic analyzer for data analysis and processing.The algorithm as harmonic analysis method is applied to harmonic analyzer,could improve the accuracy and rapidity of the harmonic analyzer.关键词
