The minimum achievable uncertainty of the Doppler frequency estimation of any unbiased estimator is given by the Cramér-Rao lower bound (CRLB). In this paper, we consider the effect of the particle trajectory via the measurement volume on the CRLB by employing the 2D model of the Gaussian envelope of the Doppler Burst Signal (DBS). The simulation results confirmed the theoretical predictions in terms...
This paper proposes a simple technique to estimate the positive sequence synchrophasor and the frequency of three-phase voltages or currents in power systems. The approach is based on the space vector transformation using a reference frame which rotates at the rated angular frequency ω0 of the power system. All the frequency components are shifted by ω0, so that the positive sequence phasor appear...
