Abstract

A control system is used in an intelligent power distribution network.
The power distribution network includes multiple branches, each of which is connected to a power source, electrical devices connected to the branches, and a normally-open device connected between two or more branches. The control system includes control elements, each control elements being associated with an electrical device connected to a branch of the distribution network.
The control system also includes a master control element associated with the normally-open device.
The master control element communicates with the control elements and, when a fault occurs on the distribution network, prevents the normally-open device from closing when information from the control elements indicate that conditions potentially disruptive to the distribution network would occur if the normally-open device were closed. The master control element permits the normally-open device to close when information from the control elements indicate that conditions potentially disruptive to the distribution network would be avoided if the normally-open device were closed.

Claims (24)

1. A control system for an intelligent power distribution network including multiple branches, each of which is connected to a power source, electrical devices connected to the branches, and a normally-open device connected between two or more branches, the control system comprising:
control elements, each control element being associated with an electrical device connected to a branch of the distribution network; and a master control element associated with the normally-open device, the master control element communicating with the control elements and, when a fault occurs on the distribution network:
preventing the normally-open device from closing when information from the control elements indicate that conditions potentially disruptive to the distribution network would occur if the normally-open device were closed, and permitting the normally-open device to close when information from the control elements indicate that conditions potentially disruptive to the distribution network would be avoided if the normally-open device were closed.
2. The control system of claim 1, wherein a branch comprises a corresponding load.
3. The control system of claim 2, wherein the power source connected to a branch provides a primary source of power to the corresponding load of the branch under predetermined operating conditions of the network.
4. The control system of claim 2, wherein the power source connected to a branch provides an auxiliary source of power to the corresponding load of the branch under predetermined operating conditions of the network.
5. The control system of claim 1, wherein a control element comprises a sensor that detects whether a fault occurs at the associated electrical device.
6. The control system of claim 1, wherein the electrical device comprises a switching system that is controllably switched between a normal operating position and a fault operating position.
7. The control system of claim 6, wherein when the electrical device is in the normal operating position, a load associated with the electrical device is supplied power from the power source connected to the electrical device.
8. The control system of claim 7, wherein the control element switches the electrical device to the fault operating position when the control element detects that a fault occurs at location that would disrupt power supplied to the associated load.
9. The control system of claim 7, wherein the control element switches the electrical device to the fault operating position in response to data from the master control element.
10. The control system of claim 1, wherein the master control element communicates with a control element through a radio link.
11. The control system of claim 1, wherein the master control element communicates with a control element through a fiber optic link.
12. The control system of claim 1, wherein the master control element communicates with a control element through an electrical wire.
13. The control system of claim 1, wherein the master control element reconfigures the power distribution network based on information from the control elements.
14. The control system of claim 13, wherein reconfiguration comprises determining a direction of current flow through the electrical device.
15. The control system of claim 14, wherein reconfiguration comprises accounting for changes in the direction of current flow through the electrical device.
16. The control system of claim 13, wherein reconfiguration comprises a primary reconfiguration that reconfigures an electrical device on the power distribution network independently of the configuration of other electrical devices and the normally-open device.
17. The control system of claim 16, wherein primary reconfiguration of the electrical device is based on a voltage and a current measurement at the electrical device.
18. The control system of claim 16, wherein the reconfiguration comprises a secondary reconfiguration that reconfigures an electrical device on the power distribution network based on input from the master control element.
19. The control system of claim 18, wherein the master control element determines whether to reconfigure the network using the primary or secondary reconfiguration based on whether communication between any of the electrical devices or the normally-open device is active.
20. The control system of claim 1, wherein the master control element monitors parameters in the power distribution network local to the normally-open device.
21. The control system of claim 1, wherein the master control element updates a configuration of the power distribution network.
22. The control system of claim 1, wherein the master control element comprises a general purpose computer.
23. The control system of claim 1, wherein conditions potentially disruptive to the power distribution network include load conditions that exceed the capacity of the power distribution network.
24. The control system of claim 1, wherein the normally-open device comprises a tie recloser.
