Abstract:
A fault is located in a power distribution system 10 having a line frequency. The power distribution system includes a plurality of phases, at least one feeder, and each feeder includes at least one segment. The fault is located by detecting a faulted phase from the plurality of phases of the power distribution system 10. A measurement signal 230 having a measurement frequency is injected into the detected faulted phase, the measurement frequency being a different frequency than the line frequency. The fault location is determined for a selected segment based on at least one measured residual current corresponding to the injected signal and a predetermined relative impedance of the power distribution system 10.
Abstract:
A system and methods that enable a restoration scheme for power distribution systems that is independent of power distribution system component configuration, the number of power distribution system components, and component settings are provided. In a power distribution system, a number of intelligent reclosers having restoration control modules are deployed that execute a restoration scheme. The intelligent reclosers constantly poll cooperating power distribution lines to determine changes in current or voltage provided by the power distribution lines. In the event of a power distribution system fault, the reclosers act in accordance to a predefined restoration scheme to reanimate the unaffected portions of the failing power distribution system.
Abstract:
A local power distribution device monitoring and control system wherein the local power distribution device monitoring and control system monitors the local power distribution device operating status. A dedicated embedded web sever maps the local power distribution device operating status information onto displayable pages and transmits the information to a utility control center using TCP/IP protocol.
