A power management system includes: customer terminals; and a power management apparatus connected to the customer terminals, wherein each of the customer terminals includes a weather forecast acquisition unit that acquires a local weather forecast for a corresponding customer terminal, and a power prediction unit that predicts a power consumption and an amount of power that can be reduced for a predetermined period based on the weather forecast, and the power management apparatus includes an integration processing unit that integrates the power consumptions and the amounts of power that can be reduced that are predicted for the respective customer terminals to calculate a total power consumption and a total amount of power that can be reduced for all of the customer terminals.
摘要:
A power consumption management system includes power consumption managers and a power supply manager. Each of the power consumption managers creates changeable power amount information with respect to a planned value of power consumption for each predetermined time range in a preset predetermined period in future, the planned value being related to a load of each piece of equipment in a building as a monitoring target. The power supply manager is connected to each of the power consumption managers through a network, decides a power change request amount for each building based on the created changeable power amount information, and transmits the decided power change request amount to each of the power consumption managers for the purpose of notification.

According to one embodiment, a PMV estimating device calculates a PMV value from an average room radiation temperature, room temperature, room humidity, room air velocity, an amount of cloth worn by a person in the room, and an amount of activity of the person in the room. The PMV estimating device includes: indoor solar radiation calculator; solar radiated article temperature estimator; and average radiation temperature estimator. The indoor solar radiation calculator calculates an amount of solar radiation entered into the room. The solar radiated article temperature estimator estimates a temperature of a solar radiated article receiving the solar radiation entered into the room, by using the amount of solar radiation entered into the room calculated by the indoor solar radiation calculator. The average radiation temperature estimator estimates the average room radiation temperature by using the temperature of the solar radiated article estimated by the solar radiated article temperature estimator.

摘要:
A plant monitoring apparatus includes: a process measuring unit; a warning determining unit; a warning selecting unit; a display processing unit; a display/setting unit; a warning criteria setting unit; a warning criteria database; and a warning criteria supplying unit. The warning determining unit determines a plurality of warning data to be issued as warnings from a large amount of process data collected by the process measuring unit on the basis of a predetermined determination criterion. The warning selecting unit compares the plurality of warning data with one or more classification criteria supplied by the warning criteria supplying unit so as to classify the plurality of warning data. Warnings are classified into categories according to the classification and the classified warnings are displayed on the display/setting unit.

According to one embodiment, an energy management system is provided, which has the DSM function of controlling energy loads. The system has a database and a load adjustment range prediction unit. The unit predicts a load adjustment range by using the history data stored in the database and outputs the load adjustment range thus predicted.
摘要:
According to one embodiment, each of the nodes incorporated in the respective electrical apparatuses that constitute a local power system establishes a communication path connected to any adjacent node, transmits and receive average supply-and-demand state data to and from the adjacent node through the communication path. Each node adjusts (increases or decreases) the power to generate or consume in it, on the basis of the average supply-and-demand state data. Each node performs a supply-and-demand control of distributed and coordinated type, in which the average supply-and-demand state value is corrected based on the value by which the power has been adjusted (increased or decreased) and the average supply-and-demand state value thus corrected is supplied to the adjacent node through the connection path.
