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 creating dynamic lists from selected areas of 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 catastrophic failure in the power system, the situation awareness being an auditory or visual comprehension which facilitates drilling down on conditions in the power system;

using the energy management system to access one or more source displays of a site;

identifying station or line elements located within a perimeter of an operator selected area to obtain vital information;

dynamically creating lists of operator defined information relative to the station or line elements from the operator selected area that are savable, recallable for future use, and display operator defined information for each element type in a list of network elements;

producing a query to obtain a unit of reactive power of an alternating current (VAR) reserves associated with the identified network elements

obtaining the vital information relative to the station or line elements;

displaying violations as violation markers;

drilling down on a particular violation by selecting a violation marker;

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

determining a location and amount of available VAR reserves that can be provided.

2. The method of claim 1, further comprising:

saving and recalling the lists for future use.

3. The method of claim 1, wherein the selected area is dragged and dropped into the new control panel tab.

4. The method of claim 3, wherein in response to being dragged and dropped a new list of elements is selected by the operator to obtain vital information for vital signs.

5. The method of claim 4, wherein the new list of elements is created by identifying station or line elements within the perimeter of the selected area.

6. The method of claim 4, wherein the information is operator definable.

7. The method of claim 4, wherein vital information is selected from at least one of, the state of the line, energization status of the lines, MegaWatt flows, MegaVar flows of the line, station load, station generation in MegaWatt and MegaVars.

8. The method of claim 7, further comprising:

automatically keeping retrieved data updated.

9. The method of claim 1, wherein the control panel has a MVAr Reserve tab that contains names of dynamically created MVar Reserve areas for a selected geographic representation of the power system.
