Robust Power System Frequency Estimation Based on a Sliding Window Approach

Robust Power System Frequency Estimation Based on a Sliding Window Approach

A novel framework for online estimation of the fundamental frequency of power system in both the single-phase and three-phase cases is proposed. This is achieved based on the consideration of the relationship among the samples within every four consecutive sliding windows and the use of the Wiener f...
