PURPOSE:To represent an equiphase line around a generator to become unstable by outputting phase data of each time section of a generator of a power system and a substation from data base for storing transient stability calculating result, and sorting the phase of time sections based on the data. CONSTITUTION:A phase sorter 11 sorts generator, substation phase data 9 at respective phases, and sends it to a coordinates forming unit 13 as phase group data 12. The unit 13 forms equiphases line coordinates 15 with the phase group data 12 and system diagram coordinates data 10, and sends it to an equiphase line display unit 14. The unit 14 which receives the coordinates 15 generates an equiphase line display command 8. An equiphase line forming data input unit inputs the data 10 and phase group data. Phase group data system coordinates input unit corresponds coordinates in a system diagram to the generator, substation data of the data 12. Coordinates to become a boundary of the phase group system diagram is calculated in the calculation of the equiphase line coordinates as equiphase line coordinates 15. |
