| 摘 要： | 提出一种通过采样数据计算信号实际频率的算法。该算法能够准确地得到信号的实际频率,并根据频率动态调整采样时间间隔,实现采样频率的自适应。由于减少了同步误差,从而降低频谱泄漏的影响。该算法实现简单,精度较高。

| Abstract: | A sampling frequency self-adaptive algorithm,and which can obtain the actual signal frequency fairly accurate,has been given.By adjusting sampling time interval the frequency calculation,the algorithm can achieve sampling frequency self-adaptive,reduce synchronous error and the influence of spectral leakage,thereby can improve the accuracy of spectral analysis and harmonic measurement for power system signal which frequency change is slow.This algorithm can be implemented easily,and has high precision. |
