This paper proposes a synchronous generator protection algorithm using Discrete Wavelet Transform for detection of fault currents. The proposed technique is implemented by using the C language and the Wavemenu of MATLAB Toolbox, and consists of normal state and internal fault state. The effectiveness of proposed method is demonstrated by MATLAB simulation package for synchronous generator, which collects the balanced and unbalanced fault currents through simulation.
