Patent number: 8477794Abstract: Techniques for using an Advanced Metering Infrastructure (AMI) system for Utility Automation (UA) purposes in a utility distribution system are disclosed herein. In an AMI system, a metering node often includes a communications option board for connecting to a wide area network (WAN), which can be shared between the AMI system and a UA system. The metering node may be near other devices that can be controlled by a utility company to monitor and control components of the utility distribution system. A data packet is received in a communication device. The communication device determines whether the received data packet is formatted according to a first protocol employed by the AMI system. If so, then the data packet is forwarded to a first device in communication with the AMI system. If not, then the data packet is forwarded to a second device in communication with the UA system.Type: GrantFiled: April 30, 2009Date of Patent: July 2, 2013Assignee: Elster Electricity, LLCInventors: David G. Hart, Edward J. Beroset, Carl J. LaPlace

Patent number: 7545285Abstract: A load control system that communicates with existing automated meter reading communications systems to interrupt and shed loads at a customer location. The system includes a master controller that listens to communications between a utility meter and the reading system. The controller receives tier and/or pricing information and will instruct a load control unit to interrupt certain loads based on the information. In addition, the system may be employed as a load shedding system where a command may be forwarded to the master controller to disconnect loads based on action levels. The command may be sent via a TCP/IP communications system to a node in the reading system and the forwarded via a radio network to the master controller to reduce latency. Predictive shedding may be performed based on forecast loads.Type: GrantFiled: February 16, 2006Date of Patent: June 9, 2009Assignee: Elster Electricity, LLCInventors: Kenneth C. Shuey, Andrew J.

Patent number: 6867958Abstract: 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.Type: GrantFiled: December 27, 2000Date of Patent: March 15, 2005Assignee: ABB Technology AGInventors: Graeme N. McClure, Jeffrey L. McElray, Sr., Robert A. Smith, Carl LaPlace, David G. Hart, William M. Egolf

Patent number: 6735534Abstract: A recloser trips on one phase for single-phase only fault conditions, or all phases for multi-phase fault conditions. During power delivery, the recloser monitors the three phases of a power line (e.g., phases A, B, and C). If a fault is detected on one phase, then a timer is started and subsequently decremented. If the timer finishes counting down while the fault is still present, then it is determined if any of the other two phases are timing a fault. If so, then all three phases are tripped; otherwise, only the faulted phase is tripped.Type: GrantFiled: March 16, 2001Date of Patent: May 11, 2004Assignee: ABB Technology AGInventors: Graeme N. McClure, Carl J. LaPlace, David G. Hart, William M. Egolf

Patent number: 6735533Abstract: A recloser trips on one phase for single-phase only fault conditions, two phases for two-phase fault conditions, or all three phases for three-phase fault conditions. During power delivery, the recloser monitors the three phases of a power line (e.g., phases A, B, and C). If a fault is detected on one phase, then a timer is started and subsequently decremented. If the timer finishes counting down while the fault is still present, then it is determined if any of the other two phases are timing a fault. If so, then those phases having a fault are tripped. Thus, only the faulted phase(s) is (are) tripped.Type: GrantFiled: March 16, 2001Date of Patent: May 11, 2004Assignee: ABB Technology AGInventors: Graeme N. McClure, Carl J. LaPlace, David G.

Patent number: 6667866Abstract: A three phase trip of a power line is prevented in a power distribution network delivering electrical power through multiple current carrying conductors and a neutral/ground line. The three phase trip is prevented after a change in the current in the neutral/ground line caused by a partial trip of a recloser. A partial trip is detected in the power distribution network, and then a threshold current is automatically adjusted from a first level to a second level for the neutral/ground line.Type: GrantFiled: December 28, 2000Date of Patent: December 23, 2003Assignee: ABB Technology AGInventors: Carl J.
