<P>PROBLEM TO BE SOLVED: To cut down on the cost of a power supply system by using a secondary battery having a smaller capacity, in the power supply system that obtains high fuel efficiency by operating a generator set at a rated output by compensating the excess and the shortage of generated power and load demand power by the charging and discharging of a secondary battery by connecting the secondary battery between the generator set and a load. <P>SOLUTION: The charging and discharging of the secondary battery 3 are performed by a control device 5 every time slot defined by dividing an operation time of one day into short times, and a charging period and a discharging period separately and individually operate the power supply system at the end stage of the time slot so that an a power accumulation level of the secondary battery is restored to that of the initial stage of the time slot. <P>COPYRIGHT: (C)2007,JPO&INPIT |
