This paper studied about main protection algorithm for generator protection scheme. In this paper, we investigated relaying method and protection for generator and performed the mathematical modeling combined between machine equation and generator equation of synchronous generator by park transformation. Furthermore, we analyzed transient phenomena by simulating three phase short fault, line to line short fault, and line to ground fault using MatLAB.
In order to derive an optical algorithm, we measured various data of transient state and internal fault of generator system and analyzed the frequencies of simulation outputs by filtering scheme using wavelet transform.
In addition we verified the superiority of the proposed algorithm by trip signal through wavelet window moving after detect the types of internal fault of the generator system.
