Digital Protective Relaying through Recursive Least Squares Identification

Abstract [en]

Parameter estimation is applied to the problem of transmission line protection. The Fourier coefficients of voltage and current are estimated using recursive least-squares identification. The estimates are then used to detect short circuits. The method is evaluated using data generated by the program EMTP
