The two-stage Newton Type Algorithm for the tracking of the power quality indicators, frequency and rate of frequency changes is presented in the paper. By this definitions for power quality indicators according to the IEEE Standard 1459-2000 were used. In the first algorithm stage the spectra of voltages and currents are estimated. Frequency and its rate of change are directly estimated from voltage input signals. In the second algorithm stage the power quality indicators are calculated. The algorithm considers frequency as an unknown model parameter simultaneously estimated with the voltage spectrum. The proposed algorithm is implemented for the analysis of transient processes during a real islanding experiment on the Rejsby Hede wind farm in Denmark.
