Abstract

A wireless radio repeater includes an antenna configured to receive a message associated with an electric power delivery system. The wireless radio repeater also includes circuitry configured to receive electrical measurement data, identify a condition of the electric power delivery system based on the electrical measurement data, and cause the antenna to re-transmit the message received via the antenna in response to identifying the condition based on the electrical measurement data.

First claim

What is claimed is:

1. A wireless radio repeater, comprising:
an antenna configured to receive a message associated with an electric power delivery system, the message including a first condition of the electric power delivery system; and
circuitry configured to perform operations comprising:
receiving electrical measurement data;
identifying a second condition of the electric power delivery system based on the electrical measurement data;
comparing the first condition from the received message with the second condition;
when the first condition corresponds with the second condition, causing the antenna to re-transmit the message received via the antenna in response to identifying the condition based on the electrical measurement data;
blocking receipt of incoming messages via the antenna while the second condition of the electric power delivery system is not identified based on the electrical measurement data;
enabling receipt of the incoming messages via the antenna in response to identifying the second condition based on the electrical measurement data, wherein the antenna is configured to receive the message after enabling the receipt of the incoming messages via the antenna; and
causing the antenna to re-transmit the message in response to the antenna receiving the message.

2. The wireless radio repeater of claim 1 , wherein the second condition comprises a low current, an overcurrent, an instantaneous voltage, a time after zero crossing of voltage or current, a sudden change in voltage or current, a low voltage, a sudden change in phase between voltage and current, a harmonic issue, or any combination thereof.

3. The wireless radio repeater of claim 1 , wherein the antenna is configured to receive the message and re-transmit the message via radio signals.

4. The wireless radio repeater of claim 1 , wherein the circuitry is configured to amplify the message received via the antenna and to cause the antenna to re-transmit the message after amplifying the message.

5. The wireless radio repeater of claim 1 , wherein the antenna is configured to receive the message at a first frequency, and the circuitry is configured to cause the antenna to re-transmit the message at a second frequency.

6. A non-transitory computer-readable medium comprising instructions that, when executed by processing circuitry, are configured to cause the processing circuitry to perform operations comprising:
receiving a message associated with an electric power delivery system, the message including a first condition of the electric power delivery system;
receiving electrical measurement data associated with an electric power delivery system;
identifying a second condition of the electric power delivery system based on the electrical measurement data;
comparing the first condition from the received message with the second condition;
operating in a closed configuration to block receipt of incoming messages while the second condition of the electric power delivery system is not identified based on the electrical measurement data;
operating in an open configuration to enable receipt of the incoming messages in response to identifying the second condition based on the electrical measurement data;
receiving the message from the device of the electric power delivery system during operation in the open configuration;
re-transmitting the message upon receiving the message during operation in the open configuration; and,
when the first condition corresponds with the second condition, performing an action based on the message received from a device of the electric power delivery system in response to identifying the first condition of the electric power delivery system.

7. The non-transitory computer-readable medium of claim 6 , wherein the action comprises re-transmitting the message, blocking flow of electrical power through a portion of the electric power delivery system, or both.

8. The non-transitory computer-readable medium of claim 6 , wherein the instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to transition from operation in the open configuration to operation in the closed configuration after a threshold period of time has elapsed since operating in the open configuration.

9. The non-transitory computer-readable medium of claim 6 , wherein the instructions, when executed by the processing circuitry, are configured to cause the processing circuitry to receive the message from a wireless radio repeater, an electrical measurement device, a sensor collector, a control system, an intelligent electronic device, or any combination thereof of the electric power delivery system.

10. A system, comprising:
a device configured to transmit a message indicative of a first condition associated with an electric power delivery system;
a repeater configured to perform operations comprising:
receiving the message transmitted by the device;
receiving electrical measurement data;
determining a second condition associated with the electric power delivery system
verifying the message based on the coordination of the first condition and the second condition; and
re-transmitting the message in response to verifying the message; and

an additional repeater configured to perform operations comprising:
receiving the message transmitted by the device;
processing second electrical measurement data associated with a second distribution line in response to receiving the message;
determining that the first condition indicated by the message is not indicated by the second electrical measurement data; and
blocking re-transmission of the message in response to determining that the first condition indicated by the message is not indicated by the second electrical measurement data.

11. The system of claim 10 , wherein the repeater is configured to perform operations comprising:
operating in an open configuration to enable receipt of incoming messages in response to identifying the second condition; and
verifying the message by receiving the message while operating in the open configuration.

12. The system of claim 10 , wherein the device comprises an electrical measurement device configured to perform operations comprising:
obtaining third electrical measurement data associated with the first distribution line; and
transmitting the message indicative of the first condition based on the third electrical measurement data.

13. The system of claim 10 , comprising an additional repeater configured to perform operations comprising:
receiving the message re-transmitted by the repeater;
receiving additional electrical measurement data;
verifying the message based on the additional electrical measurement data; and
re-transmitting the message in response to verifying the condition.
