摘要： Embodiments generally relate to a method for allowing power supplied through a cable to be determined. The method comprises receiving magnetic field data, the magnetic field data relating to a magnetic field generated by the cable, receiving reference data, the reference data relating to a current supplied to one or more monitored loads powered through the cable; based on the received magnetic field data and reference data, determining at least one parameter of a function that relates the magnetic field generated by the cable to the power supplied through a cable; and making available the at least one parameter, so that a power supplied by the cable can be determined based on the at least one parameter and a magnetic field value. The one or more monitored loads are a subset of all the loads powered through the cable.

摘要： A power generation control apparatus (14) includes a solar cell controller (18) and a range determinator (20). The solar cell controller (18), while changing at least one of an operation current and an operation voltage serving as driving variables within a first range, calculates actual power generated by a solar cell (13). The solar cell controller (18) controls the solar cell (13) to generate power by using a driving variable that maximizes the generated power within the first range. The range determinator (20), based on maximum generated power and at least one of a rated PV curve or an approximation line of the rated PV curve and a rated PI curve or an approximation line of the rated PI curve, updates the first range.

摘要： The power of a device under test (DUT) is monitored without reliance on dedicated current and voltage monitoring signals available from a semiconductor test unit. One or more magneto-resistive current sensors are provided external to, and in between the DUT and a power source. The current sensor(s) provide a detection signal proportional to the current drawn by the device from the power source. A monitoring circuit multiplies the detected current by the core voltage supply to the DUT to obtain a signal representative of the power of the device. The power signal is provided to a control circuit that operates a heat exchanger, such as on active conductive heat exchanger, to adjust the temperature of the device based on the signal representative of the power of the device. In this way the temperature of the DUT can be maintained at or near a constant set point.

摘要： The power consumption associated with use of an application is determined by causing one or more devices to execute the application. The state of the power source for each device is determined before, during, and after execution of the application. The state may include an amount of power discharged by the power source, an amount of power used to maintain a charge level of the power source, or a difference between a baseline power use and the amount of power consumed during use of the application. The determined states for the power sources of each device are used to generate an output that indicates periods of high and low power use. The output may associate these periods of power use with different characteristics of the functions that were performed during those time periods or of the devices. Using the output, a developer may optimize power use associated with an application.

摘要： A method of evaluating an optimization system is disclosed. The system is transitioned from an on state to an off state. Data is collected at time intervals for a time period before and after the system is transitioned from the on state to the off state. The transitioning occurs while a load of a particular type is active. In one embodiment, the optimization system is a Volt/VAR Optimization (VVO) system.

摘要： A method for analysis of energy savings in an electrical network includes obtaining measurements of a plurality of measurement devices linked to loads of the electrical network over a first period of time. A unified signature that characterizes the recorded measurements during the first period of time is calculated. Measurements of the plurality of measurement devices in the electrical network are obtained over a second period of time after introduction of a modification into the electrical network. A unified signature that characterizes the recorded measurements during the second period of time is calculated. The unified signature that characterizes the measurements during the second period of time is compared with the unified signature that characterizes the measurements during the first period of time to calculate energy savings resulting from introduction of the modification.
