Abstract: The effect of fast power swing conditions causes the apparent impedance 'seen' by distance protection schemes to vary over a wide range. This paper aims to moderate a directional impedance relay by adding a Wavelet Transform (WT) block and combines the outputs in a hybrid algorithm to detect a fault as well as fault during power swing, and blocks relay operation during power swings. The proposed relay has been tested for power swing conditions with different loading conditions and different power angles. In addition, testing the proposed scheme for fault conditions with different fault locations, different fault resistance, different fault types, and different inception angles had been carried out. The integrated relay had been tested on a simulated system using MatLab program.
