摘要:
A power measurement device for monitoring power delivered from a source of electrical power to a load, includes a controller configured to receive a line voltage supply input and a current input, the current input being indicative of a current drawn by the load, a load control device coupled between the controller and the load and configured to interrupt power supplied to the load through the measurement device, and a configuration module coupled to the controller and configured to enable rule-based configuration of the measurement device. The controller includes a memory in communication with a processor, the memory including program instructions for execution by the processor to calculate a value of power consumed by the load, compare the value of the power consumed to at least one predetermined control parameter, and enable the load control device to interrupt power to the load based on the comparison.

A system associated with a home energy gateway (HEG) is provided. The system includes a database having a plurality of data entry blocks, each block corresponding to a time interval and an internal database timing device configured to sync with an external real-time time server and maintain accurate time in the database. The home energy gateway is configured to add time-stamped data entries to the database. A homeowner may select a time period for a power outage so that the system sends an alert if the time period power outage is exceeded.

A method and device for managing the operating conditions of a refrigerator unit using a single sensor are disclosed. The method includes the steps of determining a sensor temperature of a refrigerator unit, determining to which a plurality of disjoint temperatures regions the temperature lies within and setting an operating condition of each of a plurality of components of the refrigerator unit based on the determined temperature region.

A device and method for more accurately measuring power consumption in a residential application without having to make connections to high voltage sources in a distribution panel. Since the device calculating the power consumption generally needs to be powered to perform its functions (e.g., plugged into wall outlet), the disclosure utilizes the power supply as a voltage source for measuring voltage without having to make connections to the panel.

System, method, and computer-executable instructions for use in operating one or more energy consuming devices. A load shedding schedule and a load shedding override schedule that is associated with an energy consuming device are determined The energy consuming device is enabled during any portion of the load shedding schedule that coincides with the load shedding override schedule. The energy consuming device is disabled during any portion of the load shedding schedule that does not coincide with the load shedding override schedule.

A power measurement device for use in a system susceptible to a plurality of potential voltage supply and current sensing connection configurations or states, operative to simulate the actual connection configuration and compute power consumed accordingly. The device includes a controller configured to receive a voltage supply input and a current measurement input; and a meter state selection device coupled to the controller, the meter state selection device being operative to selectively simulate a plurality of state settings, each state setting corresponding to a potential voltage and current sensing configuration state. The controller is operative to calculate a value of power consumed for each simulated potential configuration state, determine the simulated configuration state which provides maximum value for power consumed; and set the state of the meter state selection device to correspond to the configuration state which calculated the maximum value as the correct state for measuring power consumption.
