20110029148 | LOAD RESTORATION FOR FEEDER AUTOMATION IN ELECTRIC POWER DISTRIBUTION SYSTEMS - A method and system restores power in a power distribution network. The network includes a plurality of power sources, a plurality of loading zones, a plurality of switching devices interconnected between the plurality of power sources and the plurality of loading zones, and an intelligent electronic device associated with each of the plurality of switching devices to control the switching devices. A base network state is defined and a power restoration logic is created for the base network state. A simulation is run for the power restoration logic and then the power restoration logic is transmitted to a power restoration controller which thereafter monitors and controls the intelligent electronic devices. | 02-03-2011 |
20110098988 | Methods and Apparatus for Designing Device-to-Device Configurations Suitable to be used in a Power System - Graphical tool and method for designing device-to-device configurations used in power systems. The tool comprises software program instructions configured to allow a user to graphically associate on a monitor an intelligent electronic device (IED) selected from an available list to a corresponding switching device of the power system. For a first IED associated to corresponding switching device, the user graphically configures on the monitor a related logic by selecting one or more logical inputs/outputs and one or more target IEDs from/to which said logical inputs/outputs are to be received/sent, respectively. | 04-28-2011 |

20080225452 | Advanced Feeder Architecture With Automated Power Restoration - A method and apparatus for restoring power to loads connected to a feeder powered by a power source. The feeder is provided with a plurality of switching devices and a master electronic device which is in operative communication with the switching devices and has a plurality of power restoration plans stored therein. Upon occurrence of a fault in a zone of the feeder, the identity of the switching device which is closest to and upstream from the faulted zone relative to the power source is used in order to select a power restoration plan and restore power to some or all the loads connected to non-faulted zones of the feeder from one or more additional feeders. | 09-18-2008 |
