Abstract
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.
