Methods of Phasor Algorithm Applied on Substation Short-Circuit Impedance Calculation Analysis

Article Preview

Abstract:

Dynamic and real-time monitoring of substation, the analysis of the operating state of the substation through the phasor values of the substation. The phase of accurate measurement is a prerequisite to ensure accurate analysis Substation running state. This paper uses Fourier algorithm, recursive least squares algorithm and Kalman algorithm three methods of phasor calculation solving the acquisition voltage, current from the substation, get the results of calculation and error analysis. Come up with a more accurate method of phasor calculation. Provide a practical method for the accurate analysis of the operating state of the substation.
