摘要:
A control apparatus (50) is configured to control a control target device among load devices (61, 62) for which power supply from an electricity storage apparatus (10) is controlled based on total power consumption of the load devices (61, 62). The control apparatus (50) includes a power monitor (52) and a device controller (51). The power monitor (52) is configured to acquire a value of the total power consumption of the load devices (61, 62). The device controller (51) is configured to control the control target device to change the power consumption of the control target device so that the value of the total power consumption changes to a value having a level where the electricity storage apparatus (10) supplies the power to the load devices (61, 62) when the value of the total power consumption acquired by the power monitor (52) is at a level where the power is not supplied from the electricity storage apparatus (10) to the electrical devices (61,62).
摘要:
A standardized information acquirer (101) acquires standardized information from an electric device (300). A standardized telegraphic message sender (102) sends a standardized telegraphic message including the standardized information to a communication device (200). An unstandardized information acquirer (103) acquires unstandardized information from the electric device (300). A standardized telegraphic message receiver (201) receives the standardized telegraphic message including the standardized information. An electric device determiner (202) determines whether the electric device (300) meets a specific condition based on the standardized information included in the received standardized telegraphic message. When the electric device (300) is determined to meet the specific condition, an unstandardized telegraphic message sender (105) sends the unstandardized telegraphic message including the unstandardized information. An unstandardized telegraphic message receiver (204) receives the unstandardized telegraphic message including the unstandardized information.
摘要:
A PWM signal is generated without adding any special device by a simple method while imparting a high degree of freedom of modulation ratio and preventing extreme degradation of the efficiency. PWM signal duty creating means (22) creates two basic voltage vectors having a 60-degree phase diffidence and at least one zero vector by a conventional method. PWM signal duty re-distributing means (23) distributes the zero vector generation time ratio to three basic voltage vectors having a 120- degree phase difference between them and including the basic voltage vector present at the rear end in the direction of the inverter rotation out of the two basic voltage vectors having the 60-degree phase difference by using three vectors constituting a zero vector corresponding to the voltage command vector V* and having the same length and a 120-degree phase difference between them, and creates three basic voltage vectors having a 60-degree phase difference between them and a zero vector from the three basic voltage vectors having the 120-degree phase difference between them.

First electrical power meters (71, 72) measure electrical power supplied from a commercial power system to a residence. A second electrical power meter (73) measures electrical power generated by a distributed power source. Third power meters (74 to 84) measure electrical power supplied to each of a plurality of electric devices. A auxiliary memory (103) stores the power measurement results. An inputter (104) is used for selecting an object included in an image displayed by a display part (105). Each time a user uses the inputter (104) to select an object included in the image, the controller (101) changes the image displayed by the display part (105) to a new image in accordance with the selected object.
摘要:
In a controller (100), memories (406, 407) store device status data indicating an operation status of an electrical device, and measurement value data indicating an actual achieved value of a power consumption amount of the electrical device. When an energy saving is requested, a projector (408) calculates, based on the device status data and the measurement data, a first projection value for the power consumption amount of the electrical device in accordance with a first execution plan responding to the request, and a second projection value for the power consumption amount of the electrical device in accordance with a second execution plan not to respond to the request. A calculator (409) presents a projection result to the user.
摘要:
An energy management controller (2) acquires, for each of power lines (D1-D4) in a demand area, from devices (4, 5), measurement data relating to a power value measured by each device (4, 5). The energy management controller (2) selects, when power values are measured from a single power line, one power value as a power value measured from the power line, based on a priority assigned beforehand to each device (4, 5). Then, the energy management controller (2) manages power consumed in the demand area using the power value measured from each power line. Furthermore, the energy management controller (2) causes an operation terminal (3) to display, in a predetermined mode, information indicating the power value measured from each power line.
