AN ONLINE DISPATCHER TRAINING SIMULATOR FUNCTION FOR REAL-TIME ANALYSIS AND TRAINING

Today's power systems have become so complex that it is not easy for t he system dispatcher to realistically predict the results of outages. The situation is compounded whenever the power grid is not in its ''no rmal'' configuration due to maintenance switching or equipment failure . The authors feel that the DTS is an excellent tool that can be used to teach the dispatcher how to react under these conditions. In this p aper, the authors present an on-line implementation of the DTS which a llows the user to initialize the DTS to an EMS disturbance using data that was captured at the time of the disturbance; and place the DTS in a playback mode and go back to specific times in the scenario. The fo rmer feature allows the analyst to investigate EMS disturbances and th en train the various dispatchers to be able to recognize such disturba nces and to recover from them when they occur. The latter feature allo ws the instructor (with the trainee) to review and re-experience desir ed portions of the scenario. It is the authors' feeling that these two features will help the EMS operational staff understand their power s ystem better and help their dispatchers in dealing with operational pr oblems associated with the proper running of the system.
