Improved Recursive Newton Type Algorithm based power system frequency estimation
Improved Recursive Newton Type (IRNTA) of algorithm is used for power system frequency estimation. Recursive form of unknown parameters and covariance matrix are incorporated in the algorithm to have faster convergence. Performance of the proposed algorithm is studied through simulations and experiments. Efficacy of the proposed algorithm is also compared with RLS and KF. Studies made on industrial data also support for the superiority of the proposed algorithm.
