Variable frequency monitoring of power grid: a modified observer approach

Résumé

In most electrical networks, it can be strategic to monitor the frequency over the power grid. This monitoring can help in anticipating power dips on the network thus avoiding blackouts. The aim of this work is to monitor frequency changes with good dynamics. The proposed hybrid structure combines the advantages of a Phase Lock Loop with that of an adaptive observer. The PLL part offers a good tracking performance for slightly varying frequencies while the observer catches signal offset and significant changes in frequency. This paper gives an original technique to adjust frequency estimation dynamics. The tracking capability is validated by simulations and compared with other methods.
