Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A system and method are disclosed for synchronizing edge devices on a network, wherein the network has limited bandwidth and does not support a practical carrier sense mechanism. The edge devices transmit, using a slotted protocol, to a server located at a central data aggregation point. The server also controls a Central Transmitter, which sends messages to the edge devices to assign transmission slots and provide timing information to the edge devices to ensure that transmissions sent by devices sharing the same communication channel do not collide.

Abstract: 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.
