Fig. 8From: A new measurement algorithm for PMU in power system based on all-phase Fourier transformParameter estimation RMSE versus SNR. The estimation method in the paper enjoys greater performance in terms of accuracy and noise suppression in comparison with the literature method. In this contrast test, white Gaussian noise is injected into the observed signal with SNR 0~30 dB, and the RMSE of above two parameter estimation methods is shown versus SNRBack to article page
