DEVICE FOR MONITORING RELIABILITY OF ELECTRIC POWER SYSTEM

PURPOSE:To classify electric power systems in accordance with the unit and kind of loads, to predict load demands and reactive power by capturing numerical information or turned-on/off form information, and to perform highly accurate demand prediction by referring to meteorological data and social events. CONSTITUTION:A device for monitoring reliability of electric power system inputs the data of an electric power system by means of a fetching means 1, files 2 system information, prepares 3 the present system information, and writes the present condition of the system in a data file 4. A power generation planning means 5 prepares a near- future power generation plan and files 6 the plan. Load element predicting means 111-11n classify electric power systems in accordance with the unit and kind of loads, subdivide load demand prediction by referring to meteorological data and social events, and input demand predicted results to a file 12. Then a future system predicting means 7 performs arithmetic operation on the files 4, 6, and 12 and inputs obtained results to a future system data file 8. The means 7 checks the reliability of a power system and inputs checked results to a man-machine device 10 for operator. Therefore, a highly accurate power generation plan and tidal current can be predicted.
