Synchrophasors and frequency estimations play an increasingly important role in power systems. Discrete Fourier transform (DFT) may introduce errors into phasor and frequency estimations under dynamic conditions, such as power oscillation. A dynamic phasor and frequency estimator for phasor measurement units (PMUs) is proposed to improve accuracy by considering dynamic characteristics of power systems...
Frequency of voltage signals in power system is a key parameter to reflect the operational state of the whole system. Therefore, a new algorithm is needed to attain a more accurate frequency estimation in both steady state and dynamic conditions, for high level application such as wide area control that let the power system operate in a healthy manner. A dynamic modulation signal model is proposed...
