A New Approach to Power System Frequency Estimation

In this paper, a new time domain algorithm for power system frequency estimation is presented. The algorithm applies only ٤ samples in each window and it is also faster than some ofthe conventional methods. This feature makes the algorithm competent for using in under frequency load shedding where thefrequency relays should sense the online frequency and operate as soon as possible. Moreover, a solution to overcome thedrawbacks of time-consuming computations is proposed. Thealgorithm is successfully simulated on the IEEE ١٤ bus system and also on some practical conditions which may occur in power systems
