To obtain a graphic user interface which can search and display various kinds of data of many facilities in a large-scale system with less screen hopping and simple operations.
When 'SYSTEM MONITOR' is selected, an electric power station tree diagram display screen 401 and a monitored data display screen 402 are displayed, and the latter is divided into a monitored data list screen 402-1 and a particularly-monitored data display screen 402-2. Electric power station selecting TAB (4)-1 and data selecting TAB (4)-3 are each provided on the display screens 401, 402. When 'SYSTEM' is selected in the selecting TAB (4)-1, an electric station tree diagram (4)-2 grouped (controlled in a folder) in accordance with the connection of systems is displayed from the upper rank of voltage classes. For example, when an arbitrary electric station (500 kV-A1s/s) is selected in the electric station tree diagram (4)-2 and 'TM' is selected in the data selecting TAB (4)-3, the list of TM data of the A1s/s is displayed on the screen 402-1. By selecting the data of an arbitrary line from the list, a trend graph is displayed on the screen 402-2. The selecting TABs (4)-1, (4)-3 can each be selected independently.
