In this work, a different synchronous generator protection algorithm is presented. The proposed approach is based on the wavelet coefficients of current and voltage samples acquired from the terminal nodes of the generator. The proposed technique is termed as wavelet power (WP) relating to each phase, and able to distinguish either internal or external faults. Discrete wavelet transform (DWT) is used to get related coefficients. This technique is tested to show its ability to distinguish the faults by using two different synchronous generators in the laboratory environment and a simulation model on ATP-EMTP. MATLABtrade is used for all required computations
