Abstract

In a visual display of power transmission quality, at least three display regions are displayed. The display regions are a time-related, a location-related and a control-related display region. The time-related display region enables a selection of the time interval on the part of the user that is to be examined for a violation of one or more predetermined power quality rules.

Claims

1-14. -14. (canceled)

15. In a power transmission installation, a method for the visual display of the quality of power transmitted in the power transmission installation, the method which comprises:

displaying information in at least three display areas, the display areas including a time-related display area, a position-related display area, and a rule-related display area;

enabling a user to select, in the time-related display area, a time interval to be subjected to a rule infringement investigation with regard to one or more predetermined power quality rules;

displaying in the position-related display area one or more predetermined installation sections to be subjected to the rule infringement investigation;

displaying in the rule-related display area the predetermined power quality rules for which the rule infringement investigation is being carried out; and

following a user selection of the time interval, determining the installation sections in which a rule infringement has occurred during the selected time interval, and determining which power quality rules have been infringed, and visually marking the respective installation sections and power quality rules affected by a rule infringement in the position-related display area and in the rule-related display area.

16. The method according to claim 15, which comprises:

after displaying the installation sections in which a rule infringement has occurred in the selected time interval, and which power quality rules have been infringed,

enabling a user selection for selecting one or more of the power quality rules affected by a rule infringement; and

after a user selection, determining the installation sections affected by a rule infringement with respect to the selected power quality rules.

17. The method according to claim 15, which comprises:

after displaying the installation sections in which a rule infringement has occurred in the selected time interval, and which power quality rules have been infringed,

enabling a user selection for selecting one or more of the installation sections affected by a rule infringement; and

after a user selection, determining the power quality rules which have been affected by a rule infringement with respect to the selected installation sections.

18. The method according to claim 15, which comprises:

after displaying the installation sections in which a rule infringement has occurred in the selected time interval, and which power quality rules have been infringed,

enabling a user selection for selecting one or more of the installation sections affected by a rule infringement and one or more of the power quality rules affected by a rule infringement; and

after a user selection, determining the selected power quality rules that have been affected by a rule infringement with respect to the selected installation sections.

19. The method according to claim 15, displaying a time profile of a power quality value that represents a measure of the power quality at the respective time within the time interval in the time-related display area for the respective user-selected time interval.

20. The method according to claim 19, which comprises taking into account all predetermined installation sections and all predetermined power quality rules for determining the power quality value.

21. The method according to claim 19, which comprises taking into account only those installation sections and power quality rules which are affected by a rule infringement within the user-selected time interval for determining the power quality value.

22. The method according to claim 21, which comprises taking into account all the installation sections and all the selected power quality rules for determining the power quality value when no rule infringement is found within the time interval.

23. The method according to claim 15, which comprises:

when a user selection is made of one or more power quality rules for determining and displaying the power quality value in the time-related display area, taking into account only those selected power quality rules and those installation sections that have been affected by a rule infringement within the time interval and with respect to the selected power quality rules.

24. The method according to claim 15, which comprises, upon a user selection of one or more installation sections for determining and displaying the power quality value in the time-related display area, taking into account only the selected installation sections and those power quality rules which have been affected by a rule infringement within the time interval and within the selected installation sections.

25. The method according to claim 15, which comprises visually marking in traffic light form, with red and green traffic light symbols.

26. A display device, comprising:

a screen for visually displaying a quality of power transmitted in a power transmission installation;

a control device connected to said screen and configured to carry out the method according to claim 15;

an input device connected to said control device, said input device enabling a user input of a time interval and a user selection of one or more power quality rules and/or a user selection of one or more installation sections.

27. The display device according to claim 26, which further comprises a memory connected to said control device, said memory storing a time profile of the rule-specific and section-specific power quality value for each predetermined power quality rule and for each installation section.

28. A computer program product which, after installation on a data processing installation, programs the data processing installation to carry out the method according to claim 15.
