In this paper the principles to be applied in developing an expert system, based on CLIPS software shell, for a proper dispatching strategy in a 400 kV power substation, is presented. The process under study is complex and it is difficult to measure, so the modeling process using the PSCAD/EMTDC, EMTP/ATP and Saber software packages has performed a significant role during the design stage of the decision support system for "preventive" switching. The simulations have been used to investigate the expectable effect of changing the time of switching on each phase and to predict the transient overvoltages. The DSOP (Decision Support for Operating Policy) expert system, acts as a consultant in investigating the power system history, simulation analysis and experimental results for a proper voltage control dispatching strategy in a 400 kV power substation and for forecasting an accurate time setting for the synchronised switching relay. This expert system employs dispatcher's experience, quantitative information about the system (correct or/and faulty) behavior obtained in offline simulation studies and field tests
