摘要:
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.

According to one embodiment, 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 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.

A power reserve margin trading system according to one embodiment includes a reserve margin trading unit, a determination unit, and a trading consideration distribution unit. The reserve margin trading unit acquires a power reducible amount of a customer, trades the reducible amount as a reserve margin for demand adjustment, and acquires a consideration. The determination unit determines a rank of each customer by giving a higher rank to a customer having a smaller difference between a predicted power demand amount and a power consumption amount. The trading consideration distribution unit distributes a consideration to customers so that a portion of the consideration to be distributed varies depending on whether or not the power reduction request is transmitted.

摘要:
In a controlled object, a process variable of a controlled object process is detected by a sensor and its detection time is measured by a timer. A process signal transmitting device transmits, as a process signal, the process variable and the detection time to a control apparatus. A control variable calculating device calculates a control variable based on the received process variable and a control reference value, and transmits a control signal including the control variable and the received process variable detection time to the controlled object. In the controlled object, a control signal receiving device calculates a transmission delay, that is, a difference between control signal reception time that is measured by the timer and the transmitted process variable detection time, corrects the control variable by processing it in accordance with the transmission delay, and drives an actuator by using the corrected control variable.
