A new recursive Newton-type algorithm suitable for measurement applications in power systems is presented. In an improved form, it is used for power system frequency, phasors and spectra estimation. The key algorithm improvement is provided through a new forgetting factor tuning procedure, by which the speed of convergence and accuracy are improved. The results of computer simulation, laboratory testing and offline full-scale real-life data processing are given to show the main algorithm properties
