Abstract :
The Electromagnetic Transients Program (EMTP) is a general purpose computer program for simulating fast transient effects in electric power systems. The application of the EMTP is not easy, because it requires highly specialized expertise. This paper introduces an intelligent system to support EMTP simulation. This intelligent system works in three steps. Initially, the support system selects a base case, from a case data base to be modified to meet the user´s requirement. Then, the expert system checks the syntax and validity of the new case data. Finally, the EMTP solution is checked whether it is reasonable. The results evaluation of the EMTP solution is presented in more detail using fuzzy logic. The EMTP expert knowledge is expressed by fuzzy sets in order to check the time domain solution of the EMTP. The simulation results show that the fuzzy logic is suitable to evaluate the results of EMTP
