Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring console for centrally monitoring and operating a plurality of power generation units in one central operation room.

[0002]

2. Description of the Related Art Generally, monitoring and control of a steam power plant involves transmitting information from plant equipment and on-site operation panels provided at various parts of the plant to a monitoring and control device in a central operation room.
The central control room is used for centralized monitoring and control. A monitoring console is installed in the central control room, and the monitoring console is provided with a monitoring operation station and an operation board. That is, the monitoring operation station has a CRT display device that displays a monitoring screen of a plant and a pointing device that performs operation input on the monitoring screen, and an input device such as a console or a keyboard is installed on the operation board. In addition, a large screen device may be provided for sharing information of the entire plant.

FIG. 6 is a configuration diagram of such a monitoring and control device. In FIG. 6, two power generation units 1A and 1B
1 shows a monitoring control device that performs monitoring control in two central operation rooms 2. Each power generation unit 1A, 1
In response to B, monitoring consoles 3A and 3B and large screen devices 4A and 4B are installed, respectively, and each monitoring console 3A and 3B has a plurality (three in FIG. 6) of monitoring operating stations 5A, 5B and operation board 6A,
6B is fixedly provided.

The power generation units 1A and 1B are operated and operated by the control systems 7A and 7B based on the operation commands from the monitoring consoles 3A and 3B, and the monitoring control information of the power generation units 1A and 1B is monitored. Operation console 3A, 3
CR of monitoring operation stations 5A and 5B installed in B
It is displayed on the T display. The operator monitors the power generation units 1A and 1B on the monitoring screen displayed on the CRT display devices of the monitoring operation stations 5A and 5B. Generally, 5 to 8 per two power generation units 1A and 1B
The monitoring operation is performed by human operators.

On the other hand, in response to the recent demand for reduction of the unit price of power generation, even in a steam power plant, instead of monitoring two power generation units at once, collectively monitor and operate a large number of power generation units to save labor. It is being studied to achieve this.

FIG. 7 is a block diagram of a supervisory control device in the central operating room 2 when it is assumed that eight power generating units 1A to 1H are monitored and controlled in one central operating room 2. As can be seen from FIG.
The monitoring consoles 3A to 3H and the large screen devices 4A to 4H are installed for each 1H.

[0007]

However, in the configuration shown in FIG. 7, for example, three monitoring operation stations are required for one power generation unit.
A total of eight power generation units require 24 monitoring and operating stations. For this reason, the number of personnel required for the monitoring operation cannot be significantly reduced.

That is, in the configuration shown in FIG. 7, a large number of monitoring operation stations 5 for monitoring operation are required, so that two to three operators are required for one power generation unit 1. . Therefore, the number of personnel required for the monitoring operation as a whole is about 16 to 24. Therefore, simply concentrating the monitoring and control device in the central control room cannot significantly reduce the number of operators.

FIG. 8 is a block diagram of the monitoring console 3 in the case of the configuration shown in FIG. 7, and FIG. 8 (a) is a side view and FIG.
8B is a partially cutaway plan view of the monitoring console 3 having a linear shape, and FIG. 8C is a partially cutout plan view of the monitoring console 3 having a curved shape.

As shown in FIG. 8A, a control unit 9 is housed in a console body 8 of the monitoring console 3, and the console body 8 is provided.
A monitoring operation station 5 and an operation board 6 are provided on the upper side. The monitoring operation station has a CRT display device for displaying a plant monitoring screen and a pointing device for performing an operation input on the monitoring screen. An input device 10 such as a console or a keyboard is provided.

As shown in FIG. 8B, when the monitoring console 3 has a linear shape, the monitoring stations 5a to 5d for a plurality of power generation units are arranged on the same monitoring console 3. Will be. In this case, since the individual monitoring operation stations 5a to 5d are arranged at substantially equal intervals, the monitoring operation station 5 corresponding to which power generation unit or the adjacent monitoring operation station 5 is the same as its own power generation unit. It is difficult to distinguish whether monitoring control is performed or different, and there is a possibility that a plant is erroneously recognized or erroneously operated, which may lower operational reliability.

When one operator monitors a plurality of monitoring operation stations 5, for example, when he wants to monitor adjacent monitoring operation stations 5b and 5a from the monitoring positions of the monitoring operation stations 5c and 5d, the maximum viewing angle θ1
, The moving distances X1 and X2 are absolutely necessary.

As shown in FIG. 8C, when the monitoring console 3 has a curved shape, the monitoring operating station 5 is installed in a radial direction under the same conditions as in FIG. 8B. Therefore, the moving distances X3 and X4 that are longer than those in the case of FIG. Therefore, there is a possibility that the plant operation efficiency may be further reduced.

Therefore, the actual situation is that the operator manually moves the arrangement interval of the monitoring operation station 5 or moves it to a position where it is easy to see. However, since the monitoring operation station 5 is heavy, it is heavy. The workability is poor and may cause the surface of the monitoring console 3 to be damaged. In addition, the monitoring console to be delivered to the power generation unit is required to have earthquake resistance in terms of safety measures and measures to improve reliability. As a countermeasure, the monitoring operation station 5 is firmly mounted on the monitoring console 3 with screws or fixed bands. Since it is common to fix it, when moving it manually as described above, it was very time-consuming work to release and move the fixation and then fix it again each time .

As described above, when centralized monitoring and control of a plurality of power generation units is performed, it is difficult to reduce the number of facilities simply by centralizing the monitoring and control device in the central operation room. It was also difficult to achieve labor saving and operating cost reduction, which were the main purposes of centralization.

Is installed. The monitoring console 3 is provided with a plurality (12 in FIG. 1) of monitoring operation stations 5a to 5l and an operation board 6.

Each of the power generation units 1A to 1H is operated and controlled by the control system 7A to 7H based on a driving operation command from the monitoring console 3.
The monitoring control information of A to 1H is displayed on the CRT display devices of the monitoring operation stations 5a to 51 installed on the monitoring console 3.

The monitoring operation stations 5a to 5l installed on the monitoring console 3 are a monitoring operation unit 11 for performing a monitoring operation of the power generation unit being stopped, and a start-up operation for performing a monitoring operation of the power generation unit being stopped. Stop monitoring unit 12
And a normal operation monitoring operation unit 13 for performing a monitoring operation of the power generation unit during the normal operation. The monitoring operation stations 5a to 5l are operated by the centralized control unit 14 to operate the respective power generation units 1A to 1H. The corresponding power generation unit is allocated in accordance with.

That is, the monitoring operation of the stopped power generation unit is allocated to the two monitoring operation stations 5a and 5b arranged in the stopped monitoring operation unit 11 of the monitoring console 3, and the power generation unit being started and stopped is operated. Is assigned to the six monitoring operation stations 5c to 5h arranged in the monitoring operation unit 12 during the start / stop operation of the monitoring console 3, and the monitoring operation of the power generation unit during normal operation is performed by the monitoring console 3.

I have. Thereby, the recognition of the operator can be increased.

In the monitoring console of the monitoring control device of the plurality of power generation units 1A to 1H configured as described above, the following monitoring is performed. Since the stopped power generation unit performs steam turbine turning operation and in-plant runback operation, there is almost no need to operate auxiliary equipment, and alarm monitoring for abnormalities is mainly performed. In the monitoring operation stations 5a and 5b of the monitoring operation unit 11 during stop, a small number of operators perform centralized monitoring together with other stopped power generation units.

On the other hand, when the power generation unit is started in response to a request from the electric power system, the power generation unit is controlled by the start-stop monitoring operation unit 12 from the jurisdiction of the stop monitoring operation unit 11.
The start operation is performed by an operator involved in the start / stop of the power generation unit. When starting and stopping, it is necessary to frequently perform operations such as stopping the operation of auxiliary equipment, opening and closing electric valves for system configuration, setting adjustment of control devices such as boilers, turbines, and generators. The monitoring operation is performed by the monitoring operation station exclusively associated with the power generation unit.

After the start of the power generation unit is completed and the normal load operation based on the power supply command is started, the load control is automatically performed based on the load command from the central power supply command.
Frequent operation is not required, and monitoring of parameters of each part of the power generation unit is a central task. For this reason, the monitoring operation unit 13 during the normal operation performs the intensive monitoring operation again by a small number of operators.

In this way, a large number of monitoring operation stations 5 are installed in the start / stop operation meson operation unit 12 for performing a start / stop monitoring operation with a high operation frequency, and a plurality of power generation units are shared, so that the entire power generation unit is shared. The operation can be performed with a small number of facilities and a small number of personnel for the number of power generation units.

In the embodiment shown in FIG. 1, up to two power generation units out of eight power generation units are configured to be activated at the same time. It is considered that the operation can be performed by about 4 to 6 persons as the correspondence of the power generation unit during the start / stop operation and about 2 to 4 persons as the correspondence of the power generation unit during the normal operation,
A total of about 7 to 11 operators can respond.

FIG. 5 is a partially cutaway plan view of a convex curved portion formed in a convex shape toward the viewer when viewed from a member.

As shown in FIG. 2 (a), the monitoring console 3 is formed in a continuous curved shape of a concave shape and a convex shape, and the monitoring operation stations 5a to 5l are arranged along the curved shape. Is done. The stopped monitoring operation unit 11 corresponding to the stopped power generation unit and the normal operation monitoring operation unit 13 corresponding to the normal operation power generation unit can monitor and operate a plurality of power generation units with a small number of people. As described above, it is formed in a concave curved shape portion that is concave toward the operator as viewed from the operator.

On the other hand, the monitoring operation unit 12 during start / stop operation corresponding to the power generation unit during the start / stop operation makes it easy for a plurality of operators to monitor one or a small number of power generation units. In order to avoid complications, it is formed in a special curved shape portion that is convex toward the operator as viewed from the operator.
Thereby, the monitoring of the plurality of power generation units by a small number of people can be rationally realized.

That is, in FIG. 2A, the shape of the operation board 6 of the monitoring console 3 is such that the monitoring operation unit 11 during stop and the monitoring operation unit 13 during normal operation are concavely curved toward the operator. It is formed in a shape. On the other hand, the monitoring operation unit 12 during the start / stop operation is formed in a convex curved shape on the front side as viewed from the operator.

As shown in FIG. 2B, when the operator independently monitors the monitoring operation stations 5i to 51, the maximum viewing angle θ is monitored while monitoring the monitoring operation stations 5k and 51.
Monitoring operation stations 5i, 5k arranged outside the range
Even if the line of sight is shifted, the visual field distance Y may not be able to be confirmed due to the separation of the rails, so that a small number of people can monitor and operate a plurality of power generation units in consideration of the maximum angle visual field θ, the visual field distance Y, and the moving distance X. And the curved size R1 of the operation board 6 is set.

As shown in FIG. 2 (c), when the operator monitors the monitoring operation stations 5c to 5e with a plurality of persons, other operators monitor the monitoring operation stations 5c and 5d.

The curved size R2 of the board 6 is set.

Therefore, since the operation board 6 is curved concavely toward the front side, the moving distance of the operation board 6 can be reduced more reliably than a linear shape or a curved shape convex toward the front side. A plurality of monitoring operation stations can be monitored and operated by the number of people. In addition, since the operation board 6 is convexly curved toward the near side, the monitoring operation station adjacent to the operation board 6 more reliably than a linear shape or a concave curved shape toward the front side is more difficult to see, so that a plurality of operating stations can be operated. It becomes possible for a worker to centrally monitor and operate one or a small number of monitoring operation stations.

That is, the operation board 6 has a curved shape so that the optimum number of personnel can be allocated to each power generation unit according to the operation state of each power generation unit, thereby streamlining the monitoring of a plurality of power generation units by a small number of people. Can be achieved. As a result, erroneous recognition and erroneous operation by the operator can be reduced, and the operational reliability due to centralization is improved.

And a gentle concave arrangement that allows a small number of people to operate multiple units, assuming that the operation is progressing. Further, a special operation monitoring operation unit 15 having a convex configuration is arranged adjacent to the monitoring operation unit 12 during startup and stop so as to easily deal with troublesome troubles and special operation operation.

In FIG. 3A, the shape of the operation board 6 of the monitoring console 3 is such that the stopped monitoring operation unit 11 and the normal operation monitoring operation unit 13 have a strong concave concave shape toward the operator when viewed from the operator. Is formed. The monitoring operation unit 12 during the start-stop operation is formed in a concave gentle curved shape on the near side as viewed from the operator on the premise that the automation operation is relatively advanced. On the other hand, the special operation monitoring operation unit 15 is formed in a concave curved shape on the near side as viewed from the operator.

As shown in FIG. 3B, when the operator independently monitors the monitoring operation stations 5k to 5n, the operator operates the monitoring operation stations 5k to 5n independently so that the visual field distance Y to the monitoring operation stations is substantially the same for all four units. The monitoring operation station is arranged so that a plurality of power generation units can be monitored and operated, and the operation board 6 has a strong curved size R3.

That is, since the operation board 6 has a concavely strong curved shape on the front side, the moving distance becomes extremely small as compared with a linear shape or a convex curved shape on the front side. It becomes possible to monitor and operate a plurality of monitoring operation stations. In addition, since the operation board 6 is curved in a convex shape toward the near side, the operation monitoring operation station adjacent to the operation board 6 more reliably than the linear shape or the concave curved shape toward the near side is hard to see, and a plurality of The operator can monitor and operate one or a few monitoring operation stations.
