Abstract
Frequency deviation incurred by sudden changes of frequency introduces harmonics and inter-harmonics in the power system, which influences the accuracy of frequency estimation with the method of discrete Fourier transform (DFT). A two-layered iterative DFT (TLI-DFT) with re-sampling was presented to measure the frequency in non-steady states. A simple frequency estimation method named exponential sampling is amended to calculate the initial sampling frequency in the inner-layered process of the DFT iteration. TLI-DFT can track the frequency in non-steady states that is contaminated by decaying direct current offsets. Mean squared error of measured frequency and rate of change of frequency indicate that the proposed algorithm is valid and more accurate than the traditional one under a transient condition in the power system.
