摘要:
An electrical power system having an electricity meter connected to power lines on one side and a load on the other side, the electricity meter having a processor and memory, a communications module, a sensor, and a service disconnect switch. The system has a communications and control system adapted to send information to the electricity meter and receive information from the electricity meter. The service disconnect switch is locally operable based on a preprogrammed time delay stored in the memory of the electricity meter to restore power in a controlled fashion following a power outage. Electricity meters and electricity reconnection methods are described, as are other aspects.
摘要:
An information processing apparatus of the embodiment includes a calculator. The calculator acquires an amount of primary energy consumption at timings in a period of time and an amount of primary energy production at timings in the period of time. The amount of primary energy consumptions has been consumed and/or is estimated to be consumed by a plurality of energy-supplying apparatuses configured to supply energy to a load. The amount of primary energy productions has been produced and/or is estimated to be produced by the plurality of energy-supplying apparatuses. The calculator calculates a net amount of primary energy consumption at the timings in the period of time, based on the acquired amount of primary energy consumption and the amount of primary energy production. The calculator calculates an integrated value of the net amounts of primary energy consumption over the period of time, based on the net amounts of primary energy consumption calculated at the timings in the period of time.
摘要:
A thermal load estimating device according to an embodiment receives actual power consumption of various types of devices installed in a room, a thermal load pattern of a time-series maximum thermal load of the room, and power consumption of the various types of devices in the room; estimates a thermal load of the room at appropriate time based on the actual power consumption, the thermal load pattern, and the power consumption; and outputs an estimated thermal-load value as a result of estimation.
