Abstract:
1. A method of enabling an operator to obtain a better overview of a presentation of electrical power transmission control stations connected to power lines in a power transmission or distribution system, comprising the steps of: presenting graphical objects representing the electrical power transmission control stations together with graphical objects representing the power lines on an operator terminal display, and changing the degree of abstraction of the presentation based on an operator or operator terminal selection, wherein a change from a lower to a higher degree of abstraction of the presentation involves moving a group of graphical objects including graphical objects representing control stations closer to a condensation centre point provided on a graphical object representing a power line that is common for this group, and a change from a higher to a lower degree of abstraction of the presentation involves moving the group away from the condensation centre point provided on the graphical representation of said common power line, where the power lines are of a first and a second type and if one control station is connected to two power lines of different types, the movement of the graphical object representing this control station closer to or away from the condensation centre point of the graphical object representing the power line of the first type has a higher priority over the movement of the graphical object representing this control station closer to or away from the condensation centre point of the graphical object representing the power line of the second type, wherein having a higher priority of movement allows a larger interval of movement closer to or away from the condensation centre point of the graphical object representing the power line of the first type over the movement closer to or away from the condensation centre point of the graphical object representing the power line of the second type.
