基于小波变换和LabVIEW的电网谐波分析系统

Power Harmonic Analysis System Based on Wavelet Transform and LabVIEW

随着电力电子技术的广泛应用，谐波对电力系统的污染日益严重。为实现对电网谐波的准确分析，提出了基于小波变换和LabVIEW的谐波分析系统设计方案。系统采用小波补偿的加窗插值FFT算法进行谐波分析，提高了谐波分析精度。

With the application of power electronics widely,the harmonic pollution is more and more serious. In order to detect and analysis the harmonic of power system. The design of power harmonic test system is proposed. The system adopt FFT algorithm based on window functions and interpolation to analysis harmonic. The test precision is improved.
