In this paper a new method for digital identification of synchronous machine parameters from short circuit tests is presented. The method is based on discrete dynamic filtering algorithm. The proposed method uses digital set of measurements for the short circuit current for estimating direct axis reactance’s and time constants. A set of over-determine system of equations is constructed using digitized short circuit current samples. The identification problem is then solved using the proposed method. A case study is presented. Results are reported and evaluated.
