In the first aspect of the present invention, when the name of the functional part is input by the functional part name input unit, the functional part position display unit calls the control center to which the functional part belongs based on the input functional part name. The position of the functional part can be displayed on the distribution board located in the control center, which makes it easy to know the power supply position even if there are a large number of power supply units installed in the power generation unit. It is possible to respond quickly when an accident such as a power failure occurs, and it is easy to work even in the case of periodic inspections where work procedures are determined in advance. is there.

  In the second aspect of the invention, the abnormality transmitting means can transmit the name of the functional part equipped with the power supply unit and the abnormal state to the central control room when an abnormality occurs in any of the power supply units. Then, a subsequent response can be commanded from the central control room, and an accurate process can be performed.

  Embodiments of the present invention will be described with reference to the drawings. First, the outline of the overall configuration will be described. As shown in FIG. 1, a plurality of control centers 2 are connected to the central control room 1, and these control centers 2 include boilers, turbines and power generators. It is provided for each of various facilities 3 such as a machine, a denitration device, an electrostatic precipitator, and a desulfurization device. Next, in each of the control centers 2, a distribution board 4 corresponding to the equipment 3 under the control of the control center 2 is provided. Details of each distribution board 4 are shown in FIGS. As shown in FIG. These distribution boards 4 are 2.5 m in length and 5 m in width, and together with the name 5 of the functional part, the part to which the name 5 is attached is a switch that can be turned on and off. 6 is configured. First, what is shown in FIGS. 2 to 5 is the A control center, B control center, C control center, and D control center, the one displayed above is the front surface, and the one displayed below is the back surface. is there. Moreover, what is shown in FIG. 6 is a fuel control center, and what is displayed above is the front surface, and what is displayed below is the back surface. 7 is an emergency control center, FIG. 8 is a DC control center, FIG. 9 is a DC board, FIG. 10 is a common DC board, and FIG. What is shown is a water intake control center, and what is shown in FIG. 12 is a common control center. In these distribution boards 4, each switch 6 is provided with a display lamp (not shown). As will be described later, when either one is selected, a lighting display, a blinking display, or the like is displayed. And display the position clearly. Such a display is recognized as the functional part position display means 7 for displaying the position of the functional part. Further, if necessary, the status display is also made, such as whether the corresponding power supply is on or off, by color coding such as red or green.

  Each of the switches 6 of the various distribution boards 4 is connected to a corresponding portion of the facility 3 at the site, and the power of the functional part is controlled by operating the switch 6. The Moreover, such a power supply state is also transmitted to the central control room 1.

  Thus, the central control room 1 has a functional part name input means 8 for inputting the name of the functional part, and a power supply unit for virtually displaying the functional part controlled by the control center 2 for each control center 2. Functional part arrangement display means 9 are arranged. The functional part name input means 8 and the functional part arrangement display means 9 are specifically based on computer screen display. When the functional part name input means 8 inputs a functional part name 5 using a keyboard, the name 5 is displayed on the screen. For example, if the name 5 “A-condenser backwash valve” is input, the name 5 is displayed on the screen, and the call control and other controls thereafter serve as a selection signal on the distribution board 4 of the control center 2. Sent out. Further, when an actual operation failure such as a power supply failure occurs in the facility 3, the information is displayed on the function part name input unit 8 on the screen. By clicking on this display section, it is possible to control the calling of the functional part. FIG. 13 shows an example of the display of the functional part name input means 8 at the time of occurrence of an abnormality. As a list of alarms (general) on the computer screen 10, “seawater pump outlet valve control power cutoff” “salting” Abnormal content such as “device abnormality” and “oil recovery tank abnormality” is displayed along with the date and time of occurrence. In this case, since the item of “seawater pump outlet valve control power supply cutoff” is a power supply abnormality, clicking this position causes a power supply abnormality signal to be sent to the distribution board 4 of the control center 2 and the seawater pump. The switch 6 position in the power supply portion of the outlet valve is in a display state by blinking or the like. This information is also sent to the functional part arrangement display unit 9 and is virtually displayed together with the piping diagram of the functional part on the computer screen 11 of the functional part arrangement display unit 9 as shown in FIG. That is, on the virtual screen shown in FIG. 14, the position of the corresponding part is displayed by blinking or the like, and whether the power is locked is also displayed by orange or green.

  In such a configuration, it is assumed that a power supply abnormality has occurred in any functional part of the facility 3. For example, in the case of an accident of “seawater pump outlet valve control power supply cut-off”, the display is displayed on the computer screen 10 as shown in FIG. 13, and the operator clicks this portion to select the corresponding portion. As a result, a necessary functional part is selected, and the signal is sent to the functional part arrangement display means 9 and the corresponding distribution board 4. In the functional part arrangement display means 9, as described above, since the part is displayed together with the piping diagram in the virtual display, it is possible to immediately recognize which functional part is in which control center 2. As a result, it is possible to recognize a necessary portion remarkably quickly compared to the conventional operation of selecting a corresponding portion from a plurality of pre-printed cards, and it is accurate.

  In this way, when the corresponding part can be recognized, it goes to the corresponding control center 2 or sends a message to the operator of the control center 2 to check the corresponding part of the distribution board 4. In this case, since the power supply is abnormal, the “seawater pump outlet valve control power supply” switch 6 is blinking, and is displayed in red to indicate that it is abnormal. In accordance with this display, the operator operates the switch 6 to turn off the “seawater pump outlet valve control power source”, and repairs and inspects the relevant part of the actual facility 3. In this case, since the power of the corresponding part is not turned on, safe work is possible. When the repair work is completed, the power of the corresponding part is turned on again with the switch 6 of the distribution board 4. This state is also sent to the functional part name input means 8 and the functional part arrangement display means 9 in the central control room 1, and their state display also changes. That is, being transmitted to the central control room 1 means that an abnormality transmitting means is configured, and when an abnormality occurs in any of the power supply units, the name of the functional part equipped with the power supply unit and the abnormal state Therefore, an abnormal transmission means is configured to transmit to the central control room.

  Such an operation is similarly performed in a predetermined periodic inspection operation. Therefore, by inputting the name of the functional part of the inspection part, it is possible to easily recognize which control center 2 and the corresponding part on the distribution board 4 so that the inspection part can be turned off and can be safely inspected. It is also easy to restore the power supply at the end of the work. Also. Such recognition of the situation in the work process is fully recognized in the central control room 1.

  In the above-described embodiment, the state where the functional part name input unit 8 and the functional part arrangement display unit 9 are arranged in the central management room 1 has been described. The functional part arrangement display means 9 may be arranged in the control center 2 respectively. In addition, the specific structure of the distribution board 4 has been described on the assumption that the switch 6 is arranged vertically and horizontally. However, the functional part is displayed together with the piping diagram as if it was virtually displayed by the functional part arrangement display means 9. Means may be employed.

  Next, in the above example, when the functional part name input means 8 and the functional part arrangement display means 9 in the central control room 1 recognize the target functional part, the operator of the distribution board 4 of the control center 2 is notified. It has been described that the part is transmitted by relying on human memory and message. However, as this transmission means, for example, it is directly transmitted by a mobile phone, or the function part name input means 8 and the function are used. A method of printing a functional part selected by a printer connected to the part arrangement display unit 9 on a hard copy as a transmission unit is also possible.
