Abstract

A method of graphically representing values of at least one selected parameter at multiple monitoring points in a utility system, comprises receiving data measured at the multiple monitoring points; determining the values of the selected parameter at the multiple monitoring points, based on the received data, and using the values to generate a graphical representation of the values of the selected parameter at the multiple monitoring points, the graphical representation including shapes having (1) sizes representative of the magnitudes of the values and (2) locations representative of the hierarchy of the monitoring points. In one application, the selected parameter is at least one of electrical power and energy consumed in portions of an electrical power distribution system that correspond to the multiple monitoring points.

Claims

1. A method of graphically representing values of at least one selected parameter at multiple monitoring points in a utility system, comprising

receiving data measured at said multiple monitoring points,

determining the values of said selected parameter at said multiple monitoring points, based on said received data, and

using said values to generate a graphical representation of the values of said selected parameter at said multiple monitoring points, said graphical representation including shapes having (1) sizes representative of the magnitudes of said values and (2) locations representative of the hierarchy of said monitoring points.

2. The method of claim 1 in which said at least one selected parameter includes electrical power supplied to portions of an electrical power distribution system that correspond to said multiple monitoring points.

3. The method of claim 1 in which said at least one selected parameter includes energy consumed in portions of an electrical power distribution system that correspond to said multiple monitoring points.

4. The method of claim 1 in which said data includes at least one of measured data and virtual data for each of said multiple monitoring points.

5. The method of claim 1 in which said shapes include segments of concentric circular areas in which the angular extent of each segment represents the magnitude of at least one of said values, and the radial and circumferential locations of said segments represent the hierarchy of said monitoring points.

6. The method of claim 5 in which successive shapes along a common radial line from the center of said concentric circular areas are increasingly subordinate to other shapes on that common radius.

7. The method of claim 5 in which the angular extents of said segments of circular areas having a common radius represent the fractional size of said selected parameter for said monitoring points relative to the overall total for said parameter.

8. The method of claim 1 in which said shapes include segments of rectangular areas in which the width of each segment represents the magnitude of at least one of said values, and the locations of said segments relative to each other represent the hierarchy of said monitoring points.

9. The method of claim 8 in which said segments of rectangular areas are arranged in multiple horizontal rows with the uppermost row representing the highest hierarchical level, and the segments in successive rows below said uppermost row are increasingly subordinate to the adjacent segment in the immediately preceding row.

10. The method of claim 8 in which the lateral dimensions of the segments in a common row represent the relative values of said selected parameter for said monitoring points in a common hierarchical level.

11. The method of claim 1 in which said utility system comprises an electrical power distribution system that includes multiple mains, and which includes separate hierarchies of said monitoring points for each of said multiple mains.

12. The method of claim 1 in which said graphical representation is displayed at a selected monitoring point that is identified in the graphical representation.

13. The method of claim 1 which includes displaying data related to any selected segment in said graphical representation in response to the selection of that segment.

14. The method of claim 13 in which said displayed data includes identification of particular electrical power system components being utilized in portions of a power distribution system corresponding to the different segments.

15. The method of claim 14 in which said displayed data includes identification of selected parameters of at least some of said components.

16. The method of claim 13 in which said displayed data includes data for virtually monitored loads.

17. The method of claim 1 in which said graphical representation is generated in successive displays, beginning with a generalized display of at least a portion of the hierarchy followed by detailed displays of selected portions of the hierarchy.

18. The method of claim 17 in which said generalized display includes multiple electrical power mains, and said detailed displays include a separate hierarchy for each of said power mains.

19. The method of claim 1 in which said component identifications include data relating to at least one characteristic selected from the group consisting of electrical characteristics, mechanical characteristics and nameplate characteristics.
