Each power source switching unit ( 8 ) of a electric power system ( 1 ) constituted of a power operating system having a power generator ( 3 ) driven by an external power source ( 40 ) and an engine ( 4 ) is constituted of a means for sensing information on a selected power source and supply power in time series, calculating a supply power quantity every power source on the basis of sense data, and storing these sensing and calculated data. This power source switching unit ( 8 ), disposed every power load group, comprises a means for communication with another power source switching unit ( 8 ). A power source management system, constituted of the power source switching unit ( 8 ), comprises a means for transmitting the sensed data or calculated data of each power source switching unit ( 8 ) to the control system of the power generating system, a means for receiving data transmitted from the power source management system, and an image display means for displaying the received data by graphing. |
