Abstract

Methods are provided for creating dynamic lists from selected areas of a power system of a utility company. The utility company has an energy management system with a control panel. The energy management system is used to access one or more source displays of a site. Rubber-banding or lassoing is used to create selected areas from at least a portion of the source displays. Lists are dynamically created. Operator defined information is displayed for each element type in a list of network elements from the selected areas that have been rubber-banded or lassoed.

Claims

1. A method of injecting or removing a unit of reactive power of an alternating current (VAR) from a power system of a utility company, the utility company having an energy management system with a control panel and logic resources, comprising:

using the logic resources to provide a real time situation awareness of a potential failure relative to the utility company that can effect one or more conditions prior to an occurrence of a failure in the power system, the situation awareness being an auditory or visual comprehension in the power system;

accessing one or more source displays of the selected one or more geographic areas;

identifying station or line elements located in an operator selected one or more geographic areas to obtain information relative to station or line elements at the one or more geographic areas;

creating one or more lists of operator defined information relative to the station or line elements that are savable for future use for at least a portion of the station or line elements;

obtaining information relative to the station or line elements in selected one or more geographic areas;

in response to determining an amount of VAR reserves available, generating an overlaid geographic display by overlaying a geographic display with a superimposed VAR reserve;

using the overlayed geographic display to identify potential low or high voltage instances in the selected one or more geographic areas; and

injecting or removing a VAR in or from the selected one or more geographic areas from the power system.

2. The method of claim 1, further comprising:

providing a menu to display VAR reserves available within the selected one or more geographic areas.

3. The method of claim 2, further comprising:

selecting by the operator a show reserves element from the menu to display the VAR reserves available within selected one or more geographic areas.

4. The method of claim 1, further comprising:

for the selected one or more geographic areas generating a query to obtain the VAR reserves associated with selected network elements.

5. The method of claim 1, further comprising:

using voltage contours to identify potential low or high voltage instances.

6. The method of claim 5, wherein the information for vital signs is selected from at least one of, a state of a line, energization status of lines, MegaWatt flows, MegaVAR flows of a line, a station load and a station generation in MegaWatt and MegaVARs.

7. The method of claim 1, further comprising:

using the overlayed geographic displays to provide power flow information of the power system.

8. The method of claim 7, wherein the power flow information of the power system is in real time to determine available VAR reserves.

9. The method of claim 1, wherein available VAR reserves are displayed.

10. The method of claim 9, wherein the available VAR reserves are displayed as a summary for injection into the system and for absorption out of the system by a device type.

11. The method of claim 10, wherein the device type is selected from at least one of, generation units, capacitor banks, reactor banks and a static VAR system.

12. The method of claim 1, further comprising:

providing a VAR reserve dashboard.

13. The method of claim 12, wherein the VAR reserve dashboard is updated based on a value related to the selected one or more geographic areas.

14. The method of claim 13, wherein the update of the VAR reserve dashboard is automatically.

15. The method of claim 1, further comprising:

displaying violations as violation markers.

16. The method of claim 15, further comprising:

drilling down on a particular violation in response to receiving a selection of a violation marker via an operator input device.

17. The method of claim 15, further comprising:

showing only an elected violation marker on a monitored element tab in the control panel and all other violation markers disappear.

18. The method of claim 1, wherein the selected one or more geographic areas are placed in a new control panel tab.

19. The method of claim 18, wherein in response to placing the selected one or more geographic areas in the new control panel tab, a new list of elements is selected by the operator to obtain information for vital signs.

20. The method of claim 19, wherein the new list of elements is created by identifying station or line elements within perimeters of the selected one or more geographic areas.
