Abstract

A utility for rapid development of three dimensional representations of electrical distribution switchgear is provided. These switchgear elevations have logical connections to the switchgear devices. An elevation can be modified to any dimensions with an infinite number of combinations and arrangements of meters and protection devices to quickly and accurately represent a customer'"'"'s switchgear. Also, an event logger utility is provided for viewing, organizing and analyzing unusual behavior in a power system. The event logger utility passes a received message as an un-acknowledgeable or acknowledgeable alarm or as an event based upon the contents of a initialization file. A utility for the waveform capture is provided for viewing and analysis of waveforms (e.g., Fourier, frequency and/or harmonic analysis) captured by sophisticated metering devices. Waveforms from a device may be super-imposed for analysis. Processing of the collected waveform data to display any one of the eight waveform parameters (i.e., I_a, I_b, I_c, I_n, V_a, V_b, V_c, V_x) or a combination thereof including an "all" selection in a window tiling format is provided.

Claims

1. A method of generating a switchgear elevation window indicative of the actual switchgear, comprising:

selecting a cabinet wizard;

locating said cabinet wizard in a window;

selecting hardware wizards;

locating said hardware wizards in said window at the same relative positions on said cabinet wizard as the actual switchgear;

selecting a plurality of power monitoring or control device wizards; and

locating said plurality of power monitoring or control device wizards in said window at the same relative positions on said cabinet wizard as the actual switchgear.

2. The method of claim 1 wherein each of said power monitoring or control device wizards has dialog box associated therewith, said dialog box providing a navigational link between said window and another window displaying detailed metering, configuration or control information for the actual corresponding power monitoring or control device.

3. The method of claim 1 wherein each of said power monitoring or control device wizards has a dialog box associated therewith, said dialog box providing a navigational link between said window and another window displaying all available detailed metering, configuration and control information for the actual corresponding power monitoring or control device.

4. The method of claim 2 further comprising:

logging alarms and events of said detailed metering, configuration or control information for the actual corresponding power monitoring or control device.

5. The method of claim 2 further comprising:

collating said alarms and events into a plurality of categories for analysis.

6. The method of claim 1 wherein said power monitoring or control device wizards include trip unit wizards, meter wizards, relay wizards or control device wizards.

7. The method of claim 1 wherein said hardware wizards include handle wizards, panels wizards, of fasteners wizards.

8. The method of claim 1 further comprising:

generating said power monitoring or control device wizards.

9. The method of claim 8 wherein said step of generating further comprises:

configuring setup data for each of said power monitoring or control device wizards.

10. The method of claim 8 wherein said step of generating further comprises:

assigning an identifier each of said power monitoring or control device wizards.

11. A method of waveform capture comprising:

collecting waveform data from a power monitoring device; and

displaying at least two waveform parameters simultaneously on amplitude and phase axis.

12. The method of claim 11 wherein said at least two waveform parameters includes at least two of I_a, I_b, I_c, I_n, V_a, V_b, V_c and V_x.

13. The method of claim 12 wherein said step of displaying at least two waveform parameters comprises displaying I_a, I_b, I_c, I_n, V_a, V_b, V_c and V_x.

14. A method of generating a switchgear elevation window indicative of the actual switchgear, comprising:

selecting a graphical representation of a cabinet wizard;

locating said cabinet wizard in a window;

selecting a graphical representation of one or more hardware wizards;

locating said hardware wizards in said window at the same relative positions on said cabinet wizard as the actual switchgear;

selecting a graphical representation of a plurality of power monitoring or control device wizards; and

locating said plurality of power monitoring or control device wizards in said window at the same relative positions on said cabinet wizard as the actual switchgear.
