基于加窗插值压缩感知的谐波/间谐波检测方法
Harmonic/interharmonic detection method based on compressed sensing with windowed interpolation
摘要
Abstract
Aiming at the problem of spectrum leakage and fence effect when transforming harmonic distortion signals with compressed sensing based on DFT base,a windowed and interpolated compressed sensing(WI-CS)algorithm is pro-posed.The algorithm combines the binary sparse measurement matrix and the six-term fifth-order cosine window to con-struct a new window sparse measurement(WSM)matrix.After the sparse vector is reconstructed,the quadratic spectral line interpolation is used to accurately detect the parameters of harmonics and interharmonics.Through MATLAB simula-tion,the results show that the proposed method can have higher detection efficiency and certain anti-noise ability under the condition of less sampling data.关键词
