Abstract

A method and system (30) are disclosed for providing situational awareness to a lineworker executing a switching order in a distribution substation (10). The method includes the steps of wirelessly transmitting a status of at least one circuit breaker (20) in the distribution substation (10), wirelessly receiving the status at a location adjacent a target switch (16) in the distribution substation (10); and displaying the status to a lineworker at the location to allow the lineworker to verify the status immediately prior to executing a switching order for the target switch (16). The system (30) includes a wireless transmitter (32) to perform the transmitting step of the method and one or more wireless receivers (34) to perform the receiving and displaying steps of the method.

Claims

1. A method for providing situational awareness to a lineworker executing a switching order in a distribution substation, the method comprising the steps of:

wirelessly transmitting a status of at least one circuit breaker in the distribution substation;

wirelessly receiving the status at a location adjacent a target switch in the distribution substation; and

displaying the status to a lineworker at the location to allow the lineworker to verify the status immediately prior to executing a switching order for the target switch;

wherein the wirelessly transmitting step comprises transmitting a status for each of a plurality of circuit breakers in the distribution substation, and the displaying step comprises displaying the status for a specific circuit breaker associated with the target switch; and

wherein the wirelessly receiving step comprises receiving the status for each of a plurality of circuit breakers at a plurality of locations by a plurality of wireless receivers, each location being adjacent one of a plurality of target switches and being associated with one wireless receiver of the plurality of wireless receivers and the displaying step comprises displaying at each location the status for a specific circuit breaker associated with the target switch adjacent the location.

2. The method of claim 1 wherein the step of wirelessly transmitting comprises transmitting the status in a data packet, and further comprising the step of the decoding the data packet to display the status at the location.

3. The method of claim 1 wherein the displaying step further comprises displaying at least one additional parameter to the lineworker at the location to allow the lineworker to verify the at least one additional parameter immediately prior to executing a switching order for the target switch.

4. The method of claim 3 wherein the displaying step comprises displaying specific colors of light for each of the status and the at least one additional parameter, each color to indicate a particular condition for each of the status and the at least one additional parameter.

5. The method of claim 1 wherein the wirelessly transmitting step comprises transmitting the statuses in a data packet, and further comprising the step of decoding the data packet at each location to display the status of the specific circuit breaker associated with the target switch adjacent the location.

6. The method of claim 1 wherein the displaying step further comprises displaying at least one additional parameter at each location to allow the lineworker to verify the at least one additional parameter immediately prior to executing a switching order for the target switch at each location.

7. The method of claim 6 wherein the displaying step comprises displaying specific colors of light at each location for the status and the at least one additional parameter associated with the location, each color to indicate a particular condition for each of the status and the at least one additional parameter.

8. A situational awareness system to provide situational awareness to a lineworker executing a switching order in a distribution substation, the situational awareness system comprising:

a wireless transmitter to wirelessly transmit a status of at least one circuit breaker in the distribution substation; and

a wireless receiver positioned adjacent a target switch in the distribution substation to receive the status transmitted from the wireless transmitter, the wireless receiver including a user interface configured to display the status to a the lineworker at the target switch prior to the lineworker executing a switching order for the target switch;

wherein the wireless transmitter is connected to a protection panel and configured to transmit a status for each of a plurality of circuit breakers in the distribution substation, and further comprising a plurality of wireless receivers, each wireless receiver positioned adjacent one of a plurality of target switches in the distribution substation and configured to receive and display the status for one of the plurality of circuit breakers associated with the one of a plurality of target switches.

9. The situational awareness system of claim 8 wherein the wireless transmitter is configured to transmit the status in a data packet and the wireless receiver is configured to decode the data packet to display the status to the lineworker.

10. The situational awareness system of claim 8 wherein the wireless receiver is configured to display at least one additional parameter to a lineworker at the target switch prior to the lineworker executing the switching order for the target switch.

11. The situational awareness system of claim 8 wherein the wireless transmitter is configured to transmit said statuses in a data packet and each wireless receiver of the plurality of wireless receivers is configured to decode the data packet to display the status for the one of the plurality of circuit breakers associated with the one of a plurality of target switches.

12. The situational awareness system of claim 8 wherein each wireless receiver is configures to display at least one additional parameter to a lineworker at the target switch positioned adjacent the wireless receiver.
