Abstract: A method and system for establishing a load model (120) that utilizes a measurement from a second monitor (140) to estimate a value taken by a first monitor (150). A base load value associated with a load (160) is collected. The load model (120) is applied to the base load value, yielding an estimated load value. The estimated load value is representative of at least one measured load value for the load (160).

The monitoring device measures a utility characteristic and stores data indicative of the utility characteristic on a memory of the monitoring device. The method further includes receiving a file from the monitoring device. The file includes the device information. The device information includes at least device model information that identifies a model or type of the monitoring device.

Abstract: A monitoring system includes a discoverable wireless device, a proximity monitor, and a monitoring server. The proximity monitor is configured to automatically discover the discoverable wireless device in response to the discoverable wireless device being within a wireless range of the proximity monitor. The monitoring server is communicatively connected to the proximity monitor via a communications network. The monitoring server is configured to i) receive proximity information associated with the discoverable wireless device from the proximity monitor, and ii) transmit an instruction signal based on the received proximity information to an electrical component located remotely from the proximity monitor. The instruction signal causes the electrical component to modify an operating parameter of the electrical component.

Abstract: A system and method are disclosed for the automated discovery of devices on a network, such as a TCP/IP network using Dynamic Host Configuration Protocol (“DHCP”) and Domain Name System (“DNS”) servers. Devices on the network may be discovered, identified, and tracked by a monitoring server. Communications with the monitoring server may include identification information for each device. The identification information may be stored in DHCP option fields, transmitted with DHCP messages, and used to identify whether the device is new to the network.

Abstract: A power management architecture for an electrical power distribution system, or portion thereof, is disclosed. The architecture includes multiple intelligent electronic devices (“IED's”) distributed throughout the power distribution system to manage the flow and consumption of power from the system. The IED's are linked via a network to back-end servers. Security mechanisms are further provided which protect and otherwise ensure the authenticity of communications transmitted via the network in furtherance of the management of the distribution and consumption of electrical power by the architecture. In particular, public key cryptography is employed to identify components of the architecture and provide for secure communication of power management data among those components. Further, certificates and certificate authorities are utilized to further ensure integrity of the security mechanism.

Abstract: A method of storing data in a utility monitoring system includes monitoring a characteristic of a utility system in an intelligent electronic device (IED) to produce monitored characteristic values that are buffered in the IED. The IED is communicatively coupled to a server via a network. The monitored characteristic values are indicative of the characteristic. The method further includes storing a first monitored characteristic value of the buffered monitored characteristic values periodically at a first logging interval in a memory of the IED. The method further includes storing a second monitored characteristic value of the buffered monitored characteristic values periodically at a second logging interval in the memory of the IED in response to satisfying a criterion. The second logging interval is distinct from the first logging interval.

Abstract: An alarm management system includes an alarm management system server (“alarm server”), one or more data sources, and one or more system users (and associated user devices), all of which can be communicably connected through a communications network. The system can be configured by defining the data sources and users, defining attributes, assigning and associating attribute values with the data sources and users, and defining alarm conditions in terms of attribute values and measurements. The data sources generate measurement data which is provided to the alarm server, and the alarm server evaluates the data to determine whether the alarm conditions have been met. A data set of data sources matching alarm conditions can be generated and reported to one or more of the users.

Abstract: A method of detecting an electrical load loss following an electrical power disturbance in a monitored electrical power distribution system comprises (1) determining an expected characteristic of a parameter representing normal operation of an electrical load receiving power from the electrical power distribution system, (2) detecting a disturbance in the monitored electrical power distribution system, and (3) determining whether the load, or power circuit, or a portion of the load or power circuit, was lost as a result of the disturbance, by evaluating an actual characteristic of the parameter after termination of the disturbance with respect to the expected characteristic of said parameter.

Abstract: A system and method of synchronizing measurements between a master monitor (130 and/or 132) and a slave monitor (154 and/or 164). A system controller (110) receives master samples representing a signal characteristic from the master monitor (130 and/or 132) and slave samples representing the signal characteristic from the slave monitor (154 and/or 164). The master samples and slave samples are aligned using correlation analysis to obtain the identification of a slave sample that aligns with a predetermined master sample. This identification is transmitted to the slave monitor and used to synchronize a master measurement with a slave measurement.
