Original Paper


This paper presents a new numeric technique to estimate the operating power system frequency. The technique employs a recurrent scheme which consists of a tunable input FIR filter, frequency calculator and an averaging output filter. The recurrent structure ensures that power system frequency is efficiently tracked while minimizing signal distortions arising from harmonic and noise effects. The performance of the developed technique has been thoroughly investigated using computer simulations, and the results are provided. The effectiveness of the proposed technique is demonstrated by comparing it with three different methods reported in the literature. An experimental setup is successfully developed to evaluate the practical operation of the estimator corroborating the performance during simulations. It was confirmed that the proposed estimator performs well during static and dynamic conditions which makes it useful for the estimation of online power system frequency.
