The Technique for Accelerated Evaluation of the Instantaneous Values of Power System Performance Parameters

The method is proposed for evaluation of the instantaneous values of power system performance parameters meeting the requirements of operation on a real-time basis, processing the non-stationary and distorted signals, ensuring minimum computational delay. The method allows to evaluate the following parameters: current and voltage magnitude and phase, frequency, active and reactive power. The sampling rate of the resulting parameters corresponds to the one of the initial data.
