Abstract:
Methods, devices and systems of phase identification for a meter. One aspect includes a method of phase identification for a smart meter. One embodiment of the method includes connecting a device to at least a first phase of a poly-phase electrical system; metering at least the first phase of the poly-phase electrical system that the device is connected to for electrical consumption information using a meter; storing a first phase identifier for the first phase of the poly-phase electrical system that the device is connected to in a memory associated with the meter; and transmitting at least the first phase identifier over a network operably connected with the meter.
Abstract:
A system, in one embodiment, includes a voltage fault detection system. The voltage fault detection system may be configured to acquire a reference voltage signal from a power line to determine if a voltage sag condition is present in the power line, determine a correction voltage for correcting the voltage sag condition, use the reference voltage to produce the correction voltage, and apply the correction voltage to the power line.

Abstract:
Described herein are embodiments of methods, devices and systems of phase functionality for a meter. One aspect comprises a method of phase functionality for a meter. One embodiment of the method comprises determining a load value for each phase of a poly-phase electrical system; comparing, using a processor, the load value for each phase of a poly-phase electrical system with a respective threshold value for each phase of the poly-phase electrical system; and opening or closing one or more relays based on the comparison, wherein the one or more relays are each associated with respective phase of the poly-phase electrical system.
Abstract:
Embodiments of the invention can provide systems and methods for controlling the load of demand response metering devices. According to one embodiment of the invention, a system can be provided. The system can be operable to receive a load limit, store the load limit, determine a load demand of a location, provide an alarm when the load demand is greater than the load limit, and restrict electricity to the location when the load demand remains greater than the load limit for a predetermined amount of time.

Abstract:
In one embodiment, a system is provided including: a first intelligent electronic device (IED); and a second IED in communication with the first IED, wherein each IED comprises: a transmitter for transmitting a Generic Object Oriented Substation Event (GOOSE) message to another IED at a first timestamp; a receiver for receiving the GOOSE message from the another IED at a second timestamp; a calculator for calculating a roundtrip time based on the first timestamp and the second timestamp; and a determinator for determining if the roundtrip time is within a specified roundtrip time.
Abstract:
An electrical substation management system maintains, and activates a backup device with, a backup configuration file if a primary device becomes inactive. Peer-to-peer communication may be used in an embodiment so that primary devices communicate with other devices so configured. A master device, such as a substation computer, in an embodiment may monitor status of all connected devices status, while a primary device or a backup device may monitor primary device or IED status and select a backup device for activation if a primary device changes status, and/or retain backup configuration files.
Abstract:
Systems, methods, and apparatus for providing energy management utilizing a power meter are provided. A request for a graphical user interface may be received by a power meter in communication with an external device. The requested graphical user interface may be associated with at least one of (i) operation of the power meter or (ii) provision of electrical power to one or more loads. Based at least in part on the received request, information associated with the graphical user interface may be generated by the power meter and communicated to the external device.
