A system and method for inferring the feeder and phase of a transmitter on a plurality of electrical distribution lines. The system may include a low-voltage electrical distribution grid having one or more phases and one or more lines, a mechanism for transmitting a measuring data, a mechanism for receiving the measuring data, and a mechanism that analyzes the transmitted data to infer the phase and feed on which the transmission is injected.

A system and method for detecting theft of power in an electrical distribution grid. The system may include at least two communicating meters which form a transformer area network, a mechanism for measuring current and voltage at the meters, a mechanism for transmitting the measured current and voltage data to a data center with access to an electric grid database, and a mechanism that analyzes the transmitted data to infer unauthorized taking of electrical power.

System and method for detecting and localizing non-technical losses in an electrical power distribution grid

A system and method for inferring schematic and topological properties of an electrical distribution grid is provided. The system may include Remote Hubs, Subordinate Remotes, a Substation Receiver, and an associated Computing Platform and Concentrator. At least one intelligent edge transmitter, called a Remote Hub Edge Transmitter, may transmit messages on the electrical distribution grid by injecting a modulated current into a power main that supplies an electric meter. The Subordinate Remotes, Remote Hubs, the Substation Receiver, and the associated Computing Platform and Concentrator may contain processing units which execute stored instructions allowing each node in the network to implement methods for organizing the on-grid network and transmitting and receiving messages on the network. The Substation Receiver, Computing Platform, and Concentrator may detect and infer schematic grid location attributes of the network and publish the detected and inferred attributes to other application systems including geospatial information systems.

System and method for inferring schematic and topological properties of an electrical distribution grid

A system and methods for managing a transformer area in an electrical distribution grid having at least one substation transformer and one service transformer are presented. At least one Remote Hub governed by a policy may be provided, which collects data about the transformer area. The Remote Hub may also execute a discovery procedure to inventory Remotes in the transformer area. The Remote Hub may use the collected data to detect events, such as exceptional conditions, configuration changes, or derived results, within the transformer area. Based on the collected data, the Remote Hub is able to transmit data about the transformer area via a Substation-to-Edge channel. A method and system for forming and establishing boundaries of Transformer Area Networks is also presented. Discovery procedures may be used to form Transformer Area Networks out of Remote Hubs and Remotes powered by the same phase of the service transformer.

Methods for discovering, partitioning, organizing, and administering communication devices in a transformer area network

The present invention is directed to utility service delivery wherein distributed intelligence and networking is used in the optimization of the service delivery. The present invention employs a network of data collection nodes and aggregation nodes located on a power grid controlled by a controlling agency. The data collection nodes comprise Intelligent Communicating Devices (ICDs) and Communicating Devices (CDs), which transmit metrics they collect over the power grid from locations near meters or service transformers to the aggregation nodes. Commands, policies, and program updates may be transmitted from a server at an aggregation node to the ICDs and CDs. The ICDs are also capable of issuing control commands to the CDs and grid management devices, acting locally and/or in conjunction with other ICDs, CDs, aggregation nodes, and central controlling agencies. Through these communications and commands, utility services delivery and utilization is optimized.

A system and method for detecting and resolving conflicts in transmissions from DTs located on the edge of an electrical power distribution grid. By examining the frame and time slot of the conflict and inferring a possible DT involved in the transmission conflict and reassigning the DT's transmission to another frame and time slot, the conflict should be resolved and the data being provided by the DT is not necessarily lost nor is its receipt unreasonably delayed.

System and methods for assigning slots and resolving slot conflicts in an electrical distribution grid

A computer system at a substation of an electrical grid examines on-grid communication channels and for very channel, the system compares and correlates a GLA signal provided by a downstream transmitter on that channel to a reference GLA signal. The channel that provided the signal with the best correlation is mostly likely the channel with the transmitter. Thus, the feeder and phase of the signal can be determined from the correlation of signals.

The system may include at least two communicating meters which form a transformer area network, a mechanism for measuring current and voltage at the meters, a mechanism for transmitting the measured current and voltage data to a data center with access to an electric grid database, and a mechanism that analyzes the transmitted data to inter unauthorized taking of electrical power.

A system and method for identifying which of several candidate service transformers is powering a specific service point an electrical distribution grid are disclosed. An audio-frequency electrical signal, the detection signal, is injected onto the power line at the service point via a meter socket or electrical outlet. The Transmitter for the detection signal may be a portable device or it may be incorporated into an electrical meter. The audible or mechanical resonance caused in the service transformer by the detection signal is detected and recorded using an accelerometer or directional microphone in a Receiver. A variety of methods for fixing the Receiver at or in proximity to the service transformers are disclosed in order to adapt to variations in the siting and housing of service transformers. A variety of mechanisms and methods for collecting detection events are disclosed.
