Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for operating a thermal or nuclear power generation unit at a location remote from the unit.

[0002]

2. Description of the Related Art In the present invention, in a thermal / nuclear power plant, generally, each power generation unit (unit for each unit of a power plant) is operated by an operator in each power generation unit.

FIG. 17 shows a diagram of a thermal nuclear power plant.
It is an example of a driving device in a unit. As the plant information, the plant state information is input to the power plant operation device via the plant control device, and is displayed on the display device via the operation information processing means and the display means.

On the other hand, operation information of an operator is input from an operation device such as a touch screen of a CRT or a mouse to an operation information processing means via an operation information input means, and the operation information of the device is appropriately processed. The information is output to the plant via the information output means and the plant control device.

[0005] Here, "appropriate processing of operation information of equipment" means that, for example, certain equipment (valves, pumps, controllers, etc.) cannot be operated simultaneously on a plurality of CRTs.

[0006]

In the case of hydroelectric power generation, operation has already been carried out at a place remote from the power station, called a control station, and it is customary that there are no people on the power station side. However, in the case of thermal and nuclear power generation, there were differences as compared to hydroelectric power generation, as shown below, and it was not easy to operate remotely.

In other words, with respect to the physical quantity of the auxiliary equipment, the hydraulic power is a relatively small physical quantity mainly composed of an inlet valve, a water turbine, a generator, an AVR, a governor and the like. On the other hand, in the case of thermal power and nuclear power, the control is complicated due to the large number of auxiliary equipments due to differences in the number of digits.

In addition, the number of input points to be monitored and controlled is significantly increased due to the large amount of material. In the case of hydraulic power, the number of analog points is several tens, and the number of contact points is 100 to 200. In the case of thermal nuclear power, the number of analog points is several thousand, and the number of contact points is 100.
The order is 00 points.

Next, as for the operation of starting and stopping, the hydraulic power reaches the rated operation in about 5 minutes although it is easy to start and depends on the scale. On the other hand, nuclear power takes several days. Thermal power was faster than nuclear power, but still required longer start-up times than hydropower.

[0010] In addition, the stop is very simple because the hydraulic power stops when the valve is closed, but thermal power and nuclear power cannot be easily stopped. As for the number of operators, the hydraulic power can be operated by one person.

However, thermal power and nuclear power are operated by a driving team of about five people. Furthermore, in the case of thermal and nuclear power generation, there is a period of periodic inspection over a relatively long period. During this period of periodic inspection, it was necessary to maintain and operate many devices on the power generation unit side. For this reason, it is necessary to carry out the operation from two places, the unit side and the remote side, while cooperating with each other.

[0012] However, it has been found that confusion arises, for example, when one device can be operated on both the unit side and the remote side. For example, it was easy to imagine that when a valve was in the "automatic" position, the unit would operate "off" and the remote side would operate "on". Similarly, it can be similarly imagined that, when a controller is in the “M mode”, the unit side operates in the “C mode” and the remote side attempts to operate in the “A mode”.

The exclusion process for preventing such a situation has conventionally been performed by the operation information processing means shown in FIG. Exclusive processing means that if you try to operate the same device, and then try to select that device later,
The operation is disabled on the CRT.

[0014] However, this was realized because it was performed by one information processing device (such as a computer). However, when the operation is performed from two places, the unit side and the remote side,
Since there are two information processing devices, the exclusive processing described above cannot be easily realized.

There is a problem as described above, and in the case of thermal nuclear power generation, it has not been possible to realize a driving operation from a remote side. In view of the above, an object of the present invention is to provide a power plant operation device that enables operation of a thermal and nuclear power generation unit while cooperating with each other on the unit side and on the remote side.

[0016]

Therefore, it is possible to realize an exclusive process for permitting operation on either the unit side or the remote side for each operation device unit, and to operate while cooperating with the unit side and the remote side. Becomes possible.

Further, the present invention provides a unit-side operation device,
A mode display / operation device, a mode input unit for inputting / outputting between the device and the operation information processing unit, and a mode output unit are added to each of the remote side driving device, and the unit side driving device and the remote side driving device are added.

Thus, an operation mode is provided in which operation is permitted only in one of the unit-side operating device and the remote-side operating device, and the unit and the remote side can operate while cooperating with each other.

[0020]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 of the first embodiment is a diagram showing the basic concept of the present invention. As shown in FIG. 1, the overall configuration is largely divided into a unit side and a remote side. The two are connected by a transmission line 5.

The unit includes a plant 1, a plant control device 2, a unit operating device 100, and a display device 101 and an operating device 102 attached to the unit operating device.
It is composed of

On the remote side, the remote side driving device 200
And the display device 201 and the operation device 2 attached to the device.
02. First, the unit-side operation device 100 will be described.

In FIG. 1, a plant control device 2 is for performing operation control processing of each part of the plant 1, inputs state information representing the state of each operation element of the plant 1, and converts the state information into a unit. Is output to the side driving device 100.

The state information input means 110 inputs the state information and outputs it to the operation information processing means 120. The operation information processing means 120 first outputs the input plant information to the display device 101 via the display means 130. Here, the display device 101 is a CRT device or the like.

On the other hand, the operation device 102 is an input device such as a touch screen of a CRT, a mouse, and a keyboard. The operator performs a driving operation via the operation device 102. Specifically, it is an operation of a touch switch or the like. This operation information is output to the operation information processing unit 120 via the operation information input unit 131.

The operation processing means outputs information to the remote operation device 200 via the transmission output means 140. Next, the remote operation device 200 will be described. The transmission input means 210 transmits the input information to the operation information processing means 220
Output to The operation information processing means 220 first outputs the input plant information to the display device 201 via the display means 230.

On the other hand, the operator performs a driving operation via the operation device 102. This operation information is output to the operation information processing unit 220 via the operation information input unit 231. In the operation processing means, via the transmission output means 211,
The information is output to the unit-side operation device 100.

Here, the operation information processing means 120 of the unit-side operation device 100 and the operation information processing means 220 of the remote-side operation device 200 cooperate with each other to exchange information between the unit side and the remote side. Exclusive processing in operation is realized for driving from a location.

This will be specifically described with reference to FIGS. First, the first example is an example in which exclusion processing is performed for each operation device. An example in which an exclusive process is performed for each unit of operation on the unit side will be described with reference to FIGS.

The operation information processing means 120 has a device table. FIG. 2 shows an example of this table. The table contains the device number, the tag number, the bit UB of “operation is being selected on the unit side”, and the “operation is being selected on the remote side”.
From the bit TB. This figure shows an example, and indicates that the operation of the device N11-F001A has not been selected on either the unit side or the remote side. Bit UB = 0 of “operation selected on unit side” Bit TB = 0 of “operation selected on remote side” On the other hand, FIG. 3A shows that the operator is N11-F001A from the remote operation device 202. This is a state in which a selection (for example, a touch on a CRT or a selection with a mouse) has been made to operate the device. Bit UB = 0 of “Operation selected on unit side” = 0 Bit TB of “Operation selected on remote side” In this case, the device has already been selected on the remote side, The side makes the selection for operation impossible.

On the other hand, FIG. 3B shows that, from the state shown in FIG.
This is a case where the user selects the device to operate the device F001A. As a result, the bit UB of “operation selected on unit side” changes from “0” to “1”.

As described above, when the operation information processing means 120 manages the device table on the unit side, it is possible to determine whether or not an operation can be selected when a certain device is currently operated on the unit side. It becomes possible.

FIG. 4 is a flowchart showing this process. First, the status of the device to be operated is read from the device table. Next, it is determined whether the device is selected on the remote side. If it is selected, operation cannot be performed on the unit side.
Message is displayed on the screen.

On the other hand, if it is not selected, "1" is set to the bit "selected on unit side" in the device table. Further, the switch of the device is displayed, and the subsequent operation is accepted.

Next, with reference to FIGS. 5 to 10, an example in which an exclusion process is performed for each device operated on the remote side will be described. The basic concept is similar to that of the unit side, but because of the transmission system, there is a transmission delay.

The operation information processing means 220 has a device table similarly to the above. FIG. 5 shows an example of this table. The table contains device numbers, tag numbers,
It is composed of a bit UB of “operation selected on the unit side”, a bit TB of “operation selected on the remote side”, and a bit RB of “selection request on the remote side”. In this figure, the bit UB of “operation selected on the unit side” = “0”, the bit TB of “operation selected on the remote side” = “0”, and the bit RB of “selection request on the remote side” = “0” And N11
-F001A indicates that no operation has been selected on either the unit side or the remote side.

On the other hand, FIG. 6 shows that the bit of “operation is being selected on the unit side” = 1 and the bit of “operation is being selected on the remote side” =
0, bit of “selection request on remote side” = 0. In this case, from the operation device 102 on the unit side,
This is a state in which the operator has selected to operate the device N11-F001A.

In this state, the device has already been selected on the unit side, and selection for operation is disabled on the remote side. On the other hand, FIG. 7 shows that, from the state of FIG.
This is a case where the device 1A is selected for operation.
As a result, the bit RB of “requesting operation selection on remote side” changes from “0” to “1”.

Here, the "request" is a state in which an act of performing an operation has been applied. It is an application to the last, and it can be determined whether the operation can be actually performed after checking the state of the unit-side operation device. That is, via the transmission path,
From the remote operation device 200 to the unit operation device 100
If the “selected bit on the unit side = 0” at that time, the request is OK, and finally the “selected bit on the remote side TB is changed from“ 0 ”to“ 1 ”. can do.

As described above, when the operation information processing means 220 manages the device table on the remote side, it is possible to determine whether or not the operation can be selected when a certain device is currently operated on the remote side. It becomes possible.

FIG. 10 is a flowchart showing this processing. First, the status of the device to be operated is read from the device table. Next, the unit determines whether the device is selected.

If it is selected, the operation is not possible on the remote side, so that a message "Selecting on the unit side" is output to the display device 201. On the other hand, if it is not selected, first "requesting selection on the remote side"
Set 1 to the bit of.

Next, the operation information processing means 12 on the unit side
Refer to the selected bit in 0, and if “unit selected bit” = 1 in the device table at that time, the request is NG, and the remote operation cannot be performed as before, A message “Selecting on the unit side” is output to the display device 201.

On the other hand, if the “unit currently selected bit” = 0 in the device table at that time, the request is OK.
Therefore, the switch of the device is displayed, and the subsequent operation is accepted.

The following example is an example in which exclusive processing is performed using the concept of operation mode. In the examples so far, the unit and the remote side can operate simultaneously and simultaneously in both places unless the same equipment is used, which is very flexible.

However, there is a problem that it takes a long time to confirm whether or not the device has been selected on the other side every time the operation is performed, especially in order to confirm the operation on the remote side. Therefore, the exclusion is not performed for each device, and the concept of the operation mode is introduced to both the unit side and the remote side. It is an idea to do.

According to this, since confirmation is not performed each time a device is selected, it is possible to expect faster processing. Hereinafter, description will be made with reference to FIGS.

FIG. 11 shows an embodiment in which an operation mode is introduced. Basically, the concept of the mode display is not shown in FIG. That is, the unit-side operation device 10
Mode output means 1 which is a means for adding the mode display operation device 103 to the “0” and outputting the same to the mode display operation device 103
50, and a mode output unit 151 which is a unit for outputting from the operation mode display / operation device 103.

Similarly, a mode display operation device 203 is added to the remote operation device 200, and the mode display operation device 20
3 and a mode output means 251 as a means for outputting from the operation mode display / operation device 203.

FIG. 12 shows an example of the operation mode table. The device table is provided for each tag, but one operation mode table is provided. This table is held on both the unit side and the remote side, and information cooperation is performed between the operation information processing means 120 on the unit side and the operation information processing means 220 on the remote side, and the operation mode is set on either side. Decide on one side. The way to decide will be described later.

First, the man-machine portion will be described. FIG. 13 is a diagram showing a switch in the operation mode and a lamp in the operation mode. The right side of FIG. 12 shows an example of the operation and the lamp display.

In this example, first, the operation mode is started from the OFF state on both the unit side and the remote side. Next, from either side, the operation mode "ON"
push. Then, the operation mode (R) lamp (red lamp) blinks. In this state, the operation mode ON is being requested to the other party.

If the other party is OK, the operation mode (R) lamp is continuously turned on. An example of the logic for determining the operation mode is shown below.

In the example shown in FIG. 14, the unit side and the remote side have an equal relationship, and the side that later enters the operation mode obtains the operation mode. In the example of FIG. 15, the unit side has a higher priority than the remote side. In other words, on the unit side, the operation mode can be entered unconditionally,
The remote side cannot be turned on unless the operation mode of the unit is OFF.

In the example of FIG. 16, on the contrary to the example of FIG. 15, the remote side has a higher priority than the unit side. That is, the operation mode can be unconditionally input on the remote side, but cannot be input on the unit side unless the operation mode is OFF on the remote side.

[0056]

According to the present invention, a cooperative operation can be realized on both the unit side and the remote side. If the unit and the remote side are not the same device, they can be operated at the same time in both places at the same time, and very flexible operation can be expected.

According to the present invention, a cooperative operation can be realized on both the unit side and the remote side. In addition, by introducing the concept of the operation mode to both the unit side and the remote side, it is possible to expect an effect that the driving operation can be performed faster.
