International Classification:

G06F 1900

US Classification:

700286, 700 79, 702 60

Abstract:

A preferred embodiment of control unit for a power-distribution network comprises a processor, a memory-storage device electrically coupled to the processor, a set of computer-executable instructions stored on the memory-storage device, and an input/output interface electrically coupled to the processor. The control unit receives data from a plurality of switching devices of a power-distribution network, identifies ones of the switching devices located immediately up-line and down-line of a fault in a faulted section of the power-distribution network based on predetermined characteristics of the data, and generates and sends a first control input to at least one of the switching devices located immediately up-line and down-line of the fault to cause the at least one of the switching devices to open and thereby isolate the faulted section from a second section of the power-distribution network.

US Classification:

361 71, 361 67

Abstract:

A preferred embodiment of a system comprises a recloser electrically coupled to a voltage source of a power-distribution network and adapted to isolate a section of a distribution feeder of the power-distribution network from the voltage source in response to an overcurrent condition in the section of the distribution feeder. The system also comprises a sectionalizer electrically coupled to the section of the distribution feeder. The sectionalizer and the recloser are adapted to communicate via a data network and the recloser is responsive to control inputs sent to the recloser from the sectionalizer over the data network.

Abstract:

The invention contemplates a technique for providing loop control on a faulted overhead or underground loop system, while preventing restored current from being fed or back fed into the fault. In particular, the invention provides a method, device, and system for restoring power to a faulted loop distribution system. The inventive method includes detecting a fault on the loop distribution system, interrupting current on the faulted part of the loop distribution system, isolating the faulted part of the loop distribution system from an unfaulted part of the loop distribution system, restoring current to the unfaulted part of the loop distribution system, and preventing the current from flowing to the faulted part of the loop distribution system. The method may further include providing the current to a load.

International Classification:

G01R 31/00

US Classification:

702 59

Abstract:

A digital signal processor implementation of three algorithms used to detect high impedance faults. The algorithms can be wavelet based, higher order statistics based and neural network based. The algorithms are modified to process one second of data instead of ten seconds of data and a double buffered acquisition is connected to the output of the algorithms.
