PURPOSE:To easily recognize a power flow route by a method wherein the color of a connection display element arranged at a place where a bus displayed on a power flow diagram and symbolized for every voltage class by a single lines is connected to system constituent apparatus such as a transformer, a transmission line or the like is made identical to that of the bus. CONSTITUTION:The connection state of the following is represented by colors of connection display elements DU1 to DU30: system constituent apparatuses such as transformers Tr1 to Tr7, transmission lines Tl1 to Tl8 and the like which are displayed on a power flow diagram; and buses which are represented by single-line symbols BUS1 to BUS6 for every voltage class such as e.g. 275kV or 154kV. The colors of the connection display elements DU1 to DU30 are determined to be different for the individual buses to be connected. When a breaker and a disconnecting switch are turned on and off, they are displayed by the colors of the buses which are connected electrically. Thereby, the visual recognition property of the connection state is not deteriorated in the power flow diagram of a large-scale power system, and it is possible to easily recognize the route in which a power flow flows. |
