Abstract

A power management system is configured to comprise: a plurality of power management units (32, 36, 38, 40, 42) that divide power information about a whole facilities complex into power information about a plurality of management areas, and each of which takes partial charge and manages power information about the area pertaining thereto; and a system controller (30) that is connected to each of the power management units (32, 36, 38, 40, and 42) through a communication element, and that is for conducting power management of the whole facilities complex. When failure information is detected from the power information, an alarm signal is output by the system controller (30), and details about the failure information, which are located at a power management unit (32) for a power apparatus, are transmitted to the other power management units via a server (200).

Claims

1. A management system comprising:

a plurality of power management units which divide power information of a facility group including a plurality of facilities into a plurality of management areas and manage the management areas;

a power management unit for a power device, among the plurality of power management units, which manages power information related to a power-related device as the management area; and

a control device which is connected to the plurality of power management units by a communication element, which acquires the power information for each of the management areas, and which manages overall power information of the facility group based on the acquired power information, wherein

when the power information acquired from the power management unit includes failure information, the control device transmits to predetermined destinations a plurality of information having different amounts of information from each other with regard to the failure information.

2. The management system according to claim 1, wherein

for an alert signal and detailed information having a larger amount of information than the alert signal as the plurality of information, the control device sets different destinations for the alert signal and for the detailed information.

3. The management system according to claim 1, wherein

the control device transmits the alert signal to a power management unit for a factory among the plurality of power management units and to a display unit which displays a power management state of the facility group.

4. The management system according to claim 2, further comprising:

a server which stores the detail information and which can be accessed by the plurality of power management units.

5. The management system according to claim 4, wherein

the control device instructs the power management unit which has transmitted the power information including the failure information to transmit the detail information to the server.

6. The management system according to claim 4, wherein

the server is a mail server.

11. The management system according to claim 2, wherein

the control device transmits the alert signal to a power management unit for a factory among the plurality of power management units and to a display unit which displays a power management state of the facility group.

12. The management system according to claim 3, further comprising:

a server which stores the detail information and which can be accessed by the plurality of power management units.

7. A management system comprising:

a plurality of power management units which divide power information of a facility group including a plurality of facilities into a plurality of management areas and manage the management areas; and

a charge and discharge program memory which stores a control program which controls charging and discharging of a plurality of electricity storage devices provided in the facility group, wherein

a charge and discharge controller which controls charging and discharging of the electricity storage device downloads the control program from the charge and discharge program memory via a power management unit which manages the electricity storage device.

8. The management system according to claim 7, wherein

the charge and discharge controller inquires the power management unit at a predefined interval, and, when there is an updated version of the control program, downloads the updated version.

9. The management system according to claim 7, wherein

the charge and discharge program memory further stores an update history of the control program.

10. The management system according to claim 8, wherein

the charge and discharge program memory further stores an update history of the control program.
