  Hereinafter, an embodiment of a power consumption reduction guidance system according to the present invention will be described in detail with reference to the drawings.

  FIG. 1 shows the overall configuration of a power consumption reduction guidance system according to this embodiment. This power consumption reduction guidance system is a system for displaying on a display device a power consumption reduction guidance when power is supplied from a power receiving point to a controlled device connected to the end of a power supply system. The apparatus 12, the input / output terminal 13, the meter 14, and the equipment 15 to be controlled are shown.

  The display device 11 displays the state of the equipment 15 to be controlled, the measured value of the meter 14, and the like, and by clicking a mouse (not shown), a set value can be input or a control command can be input. it can. The equipment 15 to be controlled is, for example, controlled equipment such as air conditioning equipment, and will be described as controlled equipment below. In addition to the above-described functions, the display device 11 also has a function for displaying a power consumption reduction guidance described later.

  The control device 12 controls the entire power consumption reduction guidance system including the display device 11, the meter 14, the controlled device 15, and the like, and has various functions to be described later. The input / output terminal 13 is interposed between the control device 12, the controlled device 15, and the meter 14, and transmits and receives signals between them.

  The meter 14 is provided in each feeder part of the power supply system, and measures the power supply value in the corresponding feeder. Here, as shown in FIG. 3, the power supply system is configured to branch from the power receiving point 21 to a plurality of feeders for each of a plurality of layers and reach a terminal, and power is supplied to each controlled device 15 connected to the terminal. Supply. In the power system of FIG. 3, as meter 14, meter 1 provided in the first hierarchy and meters 2-1, 2-2, 2-3,..., 2-N provided in the second hierarchy are illustrated. In each layer, the power supplied from the corresponding feeder to the terminal controlled device 15 is measured. In many cases, the actual power system reaches not only the first and second hierarchies but also more hierarchies to the terminal controlled device 15. When such a power supply system diagram is shown on the display device 11, it is difficult to show meters at all levels because the number of meters becomes too large, as shown in FIG. In many cases, a system diagram reaching the end directly is shown. For this reason, it has been difficult for the operator to immediately grasp which controlled device 15 is supplied with power via which meter 14 only by the system diagram as shown in FIG.

  Therefore, as shown in FIG. 4, it is considered that the relationship between the meter 14 and the controlled device is displayed on the screen of the display device 11 in a table format. The present invention utilizes such a display format displayed on the display device 11, and will be described in detail below.

  In FIG. 4, the display content displayed on the display device 11 is roughly composed of a meter display unit 31, a device name display unit 32, a capacity display unit 33, and a control method display unit 34.

  In the meter display unit 31, the meter display 35 for each layer of each meter 14 shown in FIG. 3 is collectively displayed for each layer. The meter display 35 is provided corresponding to each meter 14 shown in FIG. 3, and is indicated by the name of the meter 14 (meter 1, meter 2-1,..., Meter NO). In addition, they are arranged in a layered manner in order from the left in FIG. As indicated by XXX / YYY, each meter display 35 can display the reduction desired power value XXX set by the administrator in parallel with the measured value YYY of the corresponding meter 14. The meter display 35 is configured such that the desired reduction power value XXX can be set individually. Such setting input is realized by a known setting method, for example, by clicking and specifying a setting target XXX display unit with a mouse (not shown) and operating a keyboard to input a numerical value.

  The device name display unit 32 and the capacity display unit 33 display the name of the controlled device 15 (AHU1,..., FAN3, etc.) and its rated capacity (ZZZ), and the controlled device 15 is connected to the device name display unit 32 and the capacity display unit 33. It is arranged corresponding to the meter display 35 (meters N-1 to NO) of the end layer N.

  In the control method display unit 34, control method display means 36 arranged corresponding to each controlled device 15 are displayed in an integrated manner. The control technique designation display means 36 can designate a control technique for the controlled device 15 and has a function of displaying the designated control technique. That is, the control method display unit 34 lists the control methods that can be adopted by the controlled device 15, and the control method indicated by a circle in the control method designation display means 36 is displayed in the corresponding controlled device. This means that it can be adopted. For example, when the name of the controlled device 15 is AHU1 (air conditioner), there are three control methods marked with a circle: “schedule control”, “temperature control”, and “CO2 control”, and these can be adopted. is there. Which of the plurality of control methods is the designated control method is represented by inverting and displaying the inside of a frame marked with a circle as shown in FIG. 5, for example.

  Which of the plurality of control methods is to be specified is arbitrarily determined by the administrator in accordance with the characteristics of the controlled device 15 and its installation environment, for example, by specifying the corresponding part with a mouse (not shown). Just click. Alternatively, a priority order is set in advance for each controlled device 15 according to the installation environment of the controlled device 15, and the control method of the corresponding controlled device 15 is automatically specified according to this priority order. Also good.

  Note that “schedule control” is to operate the controlled device only for a preset time. “Temperature control” is control in which, when the controlled device is in the cooling operation, the operation is performed when the temperature is higher than a preset temperature. “CO2 control” is control for introducing outside air when the CO2 concentration in the air-conditioning target space is equal to or higher than a preset concentration.

  The control device 12 uses the display method of the display device 11 to execute the power consumption reduction guidance, and includes a computer and its peripheral devices. That is, in order to perform such guidance, the control device 12 sets, as shown in FIG. 2, power reduction amount storage means 121, guidance control means 122, and guidance content execution means 123 as data realizing means. Or it is programmed.

  The power reduction amount storage unit 121 holds power reduction amount data for each controlled device 15. That is, each controlled device 15 holds a value of electric energy that can be reduced by changing the control parameter in the control method specified as described above.

  The guidance control unit 122 sets the desired reduction power value XXX set from the reduction desired power value XXX set in the meter display 35 and the power reduction amount associated with the control parameter change stored in the power reduction amount storage unit 121. In order to realize the above, how much the control parameter of the corresponding controlled device 15 is changed is calculated, and the result is displayed on the display device 11 as guidance. In this case, the controlled device 15 to be used for reducing the power consumption is the controlled device connected to the end side with respect to the meter display 35 (in the example of FIG. 5, the meter 2-1) in which the desired reduction power value XXX is set. 15 (in the example of FIG. 5, it is AHU1, AHU2, and FAN3). Then, as shown in the box display 11A in FIG. 5, in order to realize the desired reduction power value XXX, guidance display is performed on how to control these controlled devices AHU1, AHU2, and FAN3.

  The guidance content execution unit 123 outputs a parameter change command to the corresponding controlled device 15 according to the guidance content calculated by the guidance control unit 122. For example, as shown in FIG. 6, by clicking the “execute” button in the guidance display by the box display 11A, the control function execution dialog shown by the box display 11B is displayed, and the execution period is input and executed.

  In the above configuration, for example, when the administrator sets the desired reduction electric energy XXX in the meter display 35 (meter 2-1) of the meter hierarchy 2 shown in FIG. 5, the meter display 35 (see FIG. In this example, the meters N-1, N-2, and N-3) are based on the reduction desired power amount XXX set in the meter 2-1, for example, the reduction desired power amount that is divided equally is Each reduction desired power amount XXX is automatically set. Further, the meter display 35 (meter 1) higher than the meter display 35 (meter 2-1) includes each meter display (meters 2-1, 2-2,. A value obtained by adding the reduction desired power amounts XXX of -N) is set as the reduction desired power amount XXX.

  At this time, “schedule control” is designated as the control method for the controlled devices AHU1, AHU2, and FAN3 connected to the terminal meter display 35 (meters N-1, N-2, and N-3) as shown in the figure. It is assumed that The guidance control unit 122 is associated with the reduction desired power value XXX set in the meter display 35 (meters N-1, N-2, N-3) and the control parameter change stored in the power reduction amount storage unit 121. From the power reduction amount, in order to realize the set desired reduction power value XXX, how much the control parameter of the corresponding controlled device 15 is changed is calculated, and the result is shown as a box display 11A in FIG. The guidance is displayed on the display device 11. For example, for the controlled device AHU1, as shown in the figure, “Schedule operation time per hour is reduced by 20 minutes” is displayed. The same guidance display is performed for the other controlled devices AHU2 and FAN3.

  By performing such guidance display, the administrator can clearly grasp how to reduce the amount of power in which part of the power supply system configured in a complicated manner. In addition, the operation only needs to set the reduction desired power value XXX in the meter display 35 of the portion to be reduced, and the burden on the administrator is greatly reduced.

  Thereafter, in order to execute the content displayed in the guidance, the box display 11b shown in FIG. 6 is displayed, and the execution period (year / month / day / time to year / month / day / time) is displayed by the control function execution dialog. ) And operating the “execute” button, the guidance displayed is controlled, and a target power consumption reduction amount can be obtained.
