中文摘要: 根据电网参数检测对于交流采样算法的要求,提出了一种新的高精度交流采样算法,对半波傅立叶算法引入小波消噪方法进行信号预处理、运用样条插值法消除非同步采样产生的泄漏误差。仿真结果证明,这种方法与现有交流采样算法相比,具有响应速度快、精确度高的明显优点。
Abstract:In order to satisfy the requirements of measurement of the parameters of power network by using AC sampling algorithms, A new enhanced half-wave Fourier algorithm is presented in this paper. In our algorithm, wavelet denoising method is employed to preprocess the signals; spline interpolation is also applied to eliminate the leak error produced by asynchronous sampling. Simulation results demonstrate that the proposed algorithm has higher precision and faster response than the existing AC sampling algorithms.
