| Abstract: | The paper develops a power system frequency-tracking algorithm based on iterative technology. The algorithm can achieve the standard on frequency measurement precision by the real-time Fourier-filtering coefficients adjusting. The results from simulation and practical application show that the algorithm can track the change of power system frequency preferably. The algorithm can measure multi-frequency synchronously. |
