Description

The present disclosure relates to a monitor control device for monitoring and controlling a device to be monitored and controlled in a power system.

Conventionally, when a monitoring control device (system) controls a plurality of monitoring control target devices, an interlock condition set for each monitoring control target device (another monitoring control target device related to the monitoring control target device, an alarm, etc.) (State combination) is determined, and if the determination result is "control operation is impossible", the control is blocked.

As a technique related to interlock, Japanese Patent Laying-Open No. 2001-142527 (Patent Document 1) discloses a monitoring control system. In this supervisory control system, after the operator performs a series of operations on the supervisory control target device, interlock determination is performed only when the control operation command for controlling the supervisory control target device is output. The result is displayed.

Further, in the display method of the monitoring control system according to Japanese Patent Laid-Open No. 2008-123427 (Patent Document 2), interlock determination is performed in advance independently of the control operation, and the monitoring control target device is displayed in advance during the control operation. The result of the interlock determination is displayed on the display screen.

JP, 2001-142527, A JP, 2008-123427, A

However, according to the technique according to Patent Document 1, the interlock determination is performed only when the operator performs the control operation on the monitoring control target device, and thus the interlock determination result is “control operation impossible”. Therefore, the operator was performing unnecessary and unnecessary control operation.

Further, according to the technique according to Patent Document 2, the interlock determination is performed independently of the control operation or when there is a change in the input information, so that the device of “control operation is impossible” is performed. This avoids the useless operation of executing the control operation. However, there is a problem that the processing load of the supervisory control system increases when a large number of supervisory control target devices are provided in the power system, or when the states of the supervisory control target devices frequently change. ..

The present disclosure has been made in view of the above problems, and an object of a certain aspect is to prevent a user from performing useless control operation and reduce a processing load. It is to provide a supervisory control device.

<Display method of monitoring control screen>
(Normal control mode)
The monitoring control device 100 has a normal control mode and an emergency control mode as operation modes for monitoring and controlling the controlled device 2. First, the display method of the monitor control screen when the monitor control device 100 is set to the normal control mode will be described.

3 to 6 are diagrams showing the display method of the monitor control screen in the normal control mode. The monitoring control screen includes a system screen provided to the user for monitoring and controlling the controlled device 2, an interlock determination result screen, an interlock condition screen, a control operation screen, and the like.

Specifically, FIG. 3 is a diagram showing an example of the system screen in the first aspect. FIG. 4 is a diagram showing an example of a system screen in a second phase after the first phase. FIG. 5 is a diagram showing an example of a system screen in a third aspect after the second aspect. FIG. 6 is a diagram showing an example of a system screen in a fourth aspect after the third aspect.

Referring to FIG. 3, on the system screen 300, device objects 11 to 13 and 21 to 23 symbolizing each of the control target devices 2, a generator object 31 symbolizing a generator, and these devices. And electric wire objects 41 to 43 that symbolize electric wires and bus bars for connecting the generators to each other, and bus bar objects 61 and 62 are displayed. For example, the device objects 11 to 13 represent circuit breakers, and the device objects 21 to 23 represent disconnectors. The device objects representing the circuit breaker and the disconnector are represented by squares and circles, respectively, and the generator object 31 representing the generator is represented by double circles.

Further, on the system screen 300, a label (for example, “CB1”, “LS1”, etc.) for identifying each device is displayed adjacent to the device objects 11 to 13 and 21 to 23. Further, on the system screen 300, a pointer 50 for indicating an operation position on the system screen 300 is displayed.

The system screen 300 is configured to change the color of each corresponding device object according to the open/close state of each controlled device 2. For example, when the controlled device 2 is in the open state, the color of the corresponding device object is represented by black (for example, the device object 23), and when the controlled device 2 is in the closed state, the color of the device object is white (for example, the device object). 11 to 13, 21 and 22). The system screen 300 may be configured to be able to determine the open/closed state of the controlled device 2 by another display method. For example, the size of the device object may be changed according to the open/closed state, or the wording indicating the open/closed state may be displayed adjacent to the device object.

Next, referring to FIG. 4, when the user operates the input device 160 (for example, a mouse) from the state of FIG. 3 to place the pointer 50 on the device object 21, the interlock determination result screen 310 is displayed. It is displayed on the screen 300. Specifically, when the monitor control device 100 receives an operation input such that the position of the pointer 50 is superimposed on the position of the device object 21, the monitoring control device 100 determines whether or not the control operation of the control target device 2 corresponding to the device object 21 is possible. To execute. Specifically, since the control target device 2 corresponding to the device object 21 is in the “closed state”, the monitoring control device 100 determines that the control target device 2 is based on the interlock condition stored in the secondary storage device 154 or the like. Whether or not the control operation for putting the device 2 into the "open state" is possible is determined.

In the example of FIG. 4, it is determined that the control operation of the control target device 2 is impossible (prohibited), and the determination result screen 310 indicating the determination result is displayed. In addition, when it is determined that the control operation of the control target device 2 is possible (permitted), the determination result screen 310 indicating that is displayed. This allows the user to know whether or not the desired control operation can be performed before executing the desired control operation on the controlled device 2.

Next, with reference to FIG. 5, a specific operation A (for example, by a user) in a state where the determination result screen 310 is displayed as shown in FIG. 4 (for example, a state where the pointer 50 is overlaid on the device object 21). , Right-click operation), a condition screen 320 including interlock conditions defined in advance for the control target device 2 corresponding to the label “LS1” (device object 21) is displayed on the system screen 300. Hereinafter, for ease of explanation, the control target device 2 corresponding to the label “LS1” (device object 21) may be referred to as “control target device X”.

The condition screen 320 includes a status column 322 indicating the open/closed state (“closed state” in the example of FIG. 5) of the control target device X, a result column 324 indicating the determination result, and whether or not the control operation of the control target device 2 is possible. A condition column 326 indicating the interlock condition used for the determination is included. Specifically, the condition column 326 shows a condition for permitting a control operation (open operation) for opening the control target device 2 in the open state. Typically, when any of the conditions (1), (2) and (3) in the condition column 326 is satisfied, the interlock condition is satisfied. The condition (1) is satisfied when the control target device 2 corresponding to the label “CB1” is in the open state. The condition (2) is satisfied when each control target device 2 corresponding to the label “CB2” and the label “CB3” is in the open state. The condition (3) is satisfied when the controlled device 2 corresponding to the label “CB2” is in the open state and the controlled device 2 corresponding to the label “LS3” is in the closed state. This allows the user to first understand what control operation should be performed on which control target device 2 in order to permit the desired control operation to the control target device 2.

Subsequently, with reference to FIG. 6, when the monitor control device 100 receives an input of a specific operation B (for example, a left click operation) from the user in a state where the condition screen 320 is displayed, the monitoring control device 100 determines that the control target device X has A control operation screen 330 for executing a control operation is displayed on the system screen 300. It should be noted that the monitoring control device 100 may be configured to display the control operation screen 330 on the system screen 300 when an input of the operation B is received from the user while the determination result screen 310 is being displayed.

The control operation screen 330 displays a field 332 indicating the control target device 2 (the control target device X in the example of FIG. 6) that is the target of the output of the control operation signal, and a control operation for closing the control target device X. A close button 334 for accepting, an open button 336 for accepting a control operation for opening the controlled device X, and a control operation signal corresponding to the control operation accepted by the close button 334 or the open button 336 are sent to the controlled device X. And an output button 338 for outputting. For example, the user can output an open operation signal to the controlled device X by selecting (for example, pressing) the open button 336 and then selecting the output button 338.

From the above, an example of the operation procedure of the user in the normal control mode is as follows. First, while checking the system screen 300, the user moves the pointer 50 so as to be superimposed on the device object corresponding to the desired controlled device 2 (see FIGS. 3 and 4).

When the user confirms the determination result screen 310 displayed on the system screen 300 and the determination result is “controllable”, the user performs operation B (left click operation) to display the control operation screen 330 (FIG. 6). Then, the user can output the control operation signal to the desired controlled device 2 by selecting the close button 334 or the open button 336 of the control operation screen 330 and further selecting the output button 338. ..

On the other hand, the user confirms the determination result screen 310 and, if the determination result is “control disabled”, performs the operation A (right-click operation) to display the condition screen 320 (see FIG. 5 ). The user confirms the condition screen 320 and specifies which control target device 2 needs to be opened or closed. The user moves the pointer 50 so as to be superimposed on the device object corresponding to the specified control target device 2, and repeats the above operation.

(Emergency control mode)
Here, the display method of the monitor control screen when the monitor control device 100 is set to the emergency control mode will be described. The emergency control mode is a mode used, for example, when an emergency occurs in which the state information on the specific control-target device 2 cannot be properly acquired due to some trouble.

FIG. 7 and FIG. 8 are diagrams showing a system screen display method in the emergency control mode. Specifically, FIG. 7 is a diagram for explaining the condition screen in the emergency control mode. 8: is a figure which shows the aspect after the aspect of FIG.

When the supervisory control device 100 receives an operation input on the system screen 300 where the pointer 50 is superimposed on the device object, the monitoring control device 100 determines whether the control operation of the control target device 2 corresponding to the device object is permitted or not. The judgment is executed and the judgment result screen 310 is displayed (see FIGS. 3 and 4).

Referring to FIG. 7, when monitoring control apparatus 100 receives an input of operation A (for example, right-click operation) from the user in a state where determination result screen 310 is displayed as shown in FIG. 4, the interlock condition is set. The condition screen 320A shown is displayed on the system screen 300. On the system screen 300, mode information 350 indicating that the emergency control mode is in progress is displayed.

The condition screen 320A is obtained by replacing the condition column 326 in the condition screen 320 shown in FIG. 5 with a condition column 326A. Specifically, the condition column 326A has a configuration in which a check box group 327 including a plurality of check boxes is added to the condition column 326. Each check box is provided corresponding to each interlock condition (for example, on the right side), and is an object for accepting an operation for invalidating the corresponding interlock condition.

Here, for example, the user understands that an emergency has occurred and the state information of the label “CB3” cannot be properly acquired (state information is incorrect, or state information cannot be received). Imagine a situation where In this case, as shown in FIG. 8, the user moves the pointer 50 to invalidate the interlock condition for the label “CB3”, and the check box arranged on the right side of the label “CB3” in the condition column 326A. Select. As a result, the interlock condition for the label “CB3” can be nullified, and therefore the condition (2) is satisfied when the controlled device 2 corresponding to the label “CB2” is in the open state.

When the user moves the pointer 50 so as to be superimposed on the device object 21 on the system screen 300 after the selection operation of the check box, the monitoring control device 100 ignores the interlock condition regarding the label “CB3” and sets the interlock condition. The lock determination is executed and the determination result screen 310 is displayed.

Thereby, the user can appropriately deal with the emergency situation by exceptionally invalidating a part of the interlock condition during the emergency control mode.

<Functional configuration>
FIG. 9 is a schematic diagram showing a functional configuration of the monitoring control device 100. Referring to FIG. 9, monitoring control device 100 includes a state information acquisition unit 201, an operation input unit 205, an interlock determination unit 207, and a display control unit 220. Each of these functions is realized, for example, by the processor 150 executing a program stored in the secondary storage device 154. The monitoring control device 100 further includes a state information storage unit 203 realized by the main storage device 152 and the secondary storage device 154, and a condition information storage unit 209. It should be noted that some or all of these functions may be configured to be realized by hardware.

The state information acquisition unit 201 acquires information (state information) indicating various states of the control target device 2 from each of the control target devices 2A to 2N. The status information acquisition unit 201 stores the acquired status information in the status information storage unit 203 and sends it to the display control unit 220 (system display processing unit 222). The state information includes at least information indicating the open/closed state, and may include type information of the control target device 2, identification information, and the like.

The operation input unit 205 receives various operation inputs from the user via the input device 160. Specifically, the operation input unit 205 receives a control operation input by the user and a display operation input on the system screen 300.

The interlock determination unit 207 determines whether or not the control operation of the control target device 2 is possible based on the interlock condition stored in the condition information storage unit 209 and the state information of the control target device 2. Specifically, when the operation input unit 205 receives a designation operation that designates the control-target device 2 on the system screen 300, the interlock determination unit 207 determines the control operation of the designated control-target device 2. Execute the determination of availability. The designation operation includes an operation of superimposing the pointer 50 indicating the operation position of the user on the device object indicating the control target device 2 on the system screen 300. The interlock determination unit 207 sends the interlock determination result and the interlock condition used for the determination to the display control unit 220 (determination result display processing unit 224).

The mode setting unit 211 sets the operation mode of the monitoring control device 100 to the normal control mode or the emergency control mode. For example, the mode setting unit 211 switches between the normal control mode and the emergency control mode by receiving an operation signal from a dedicated input device (for example, a dedicated button) for setting the mode. In this case, the user can change the operation mode of the monitoring control device 100 by operating the dedicated input device.

The display control unit 220 controls the display on the display 158 based on various information and various instructions from the user. Specifically, the display control unit 220 includes a system display processing unit 222, a determination result display processing unit 224, and a control operation display processing unit 226.

The system display processing unit 222 generates an overall system diagram (for example, a system screen 300) that symbolizes the entire power system to which the control target devices 2A to 2N are connected, based on each state information of the control target devices 2A to 2N. Then, the entire system diagram is displayed on the display 158. Specifically, the systematic display processing unit 222 causes the display 158 to display various objects as shown in FIG. 3 and the like, and also displays various objects according to the state information (whether the object is open or closed). The display mode (for example, color) of is changed.

The determination result display processing unit 224 displays the interlock determination result (for example, the determination result screen 310) on the display 158. In addition, when the operation input unit 205 receives a specific operation (for example, operation A) in the state where the determination result is displayed, the determination result display processing unit 224 indicates the control operation of the designated control target device 2. The condition screen 320 including the interlock condition used for the determination of approval/disapproval is further displayed on the display 158. Specifically, the determination result display processing unit 224 displays the condition screen 320 when the operation A is accepted in a state in which the determination result indicating that the control operation of the designated control target device 2 is impossible is displayed. Let

When the monitoring control device 100 is set to the emergency control mode by the mode setting unit 211, the determination result display processing unit 224 invalidates the interlock condition for each of the plurality of interlock conditions included in the condition screen 320. An object (for example, a check box group 327) for accepting an operation to be performed is further displayed. In this case, when the operation input unit 205 receives a selection operation for the object, the interlock determination unit 207 uses the remaining interlock condition other than the interlock condition corresponding to the selected object to control the device to be controlled. Whether or not the control operation of 2 is possible is determined. That is, the interlock determination unit 207 ignores the interlock condition corresponding to the selected object and executes the interlock determination.

The control operation display processing unit 226 causes the display 158 to display the control operation screen 330 for executing the control operation of the control target device 2. Specifically, in the control operation display processing unit 226, when the determination result display processing unit 224 displays the determination result indicating that the control operation is possible on the display 158, the operation input unit 205 performs the specific operation ( For example, when the operation B) is received, the control operation screen 330 is displayed.

<Processing procedure>
FIG. 10 is a diagram illustrating an example of a processing procedure of the monitoring control device 100. Here, a flow until the user executes a control operation (for example, an “open” operation) of the control target device 2 corresponding to the device object (for example, the device object 21) displayed on the system screen 300 will be described. .. Each step shown in FIG. 10 is typically executed by the processor 150. It is assumed that the processor 150 periodically acquires the state information of the controlled device 2 via the communication interface 156.

Referring to FIG. 10, processor 150 causes display 158 to display system screen 300, which is an overall view of the power system, based on the state information of controlled device 2 (step S10). The processor 150 receives an operation input from the user via the input device 160, and determines whether or not the pointer 50 is overlaid on any of the device objects 11 to 13 and 21 to 23 on the system screen 300 (step S12). ).

When the pointer 50 is not overlaid on the device object (NO in step S12), the process of step S12 is repeated. When the pointer 50 is overlaid on any of the device objects (YES in step S12), the processor 150 identifies the control target device 2 (control target device X) corresponding to the device object 21 (step S14). ). For example, the processor 150 performs the identification by referring to the device identification information (device ID, device number, etc.) stored in the secondary storage device 154 and associated with the device object.

Subsequently, the processor 150 reads the interlock condition defined for the control-target device X and the state information of each control-target device 2 necessary for determining whether or not the control operation of the control-target device X is possible ( Step S16). The processor 150 determines whether or not the control operation of the controlled device X is possible based on the read interlock condition and the state information of each controlled device 2 (step S18). Typically, when the control target device X is in the open state, the processor 150 determines whether or not a control operation (closing operation) for closing the control target device X is possible, and the control target device X is If it is in the closed state, it is determined whether or not a control operation (open operation) for opening the control target device X is performed.

If the control operation is “OK” (YES in step S18), processor 150 causes display 158 to display determination result screen 310 indicating that the control operation is possible (step S20). Subsequently, the processor 150 determines whether or not an operation B (left click operation on the device object 21) has been received from the user via the input device 160 (step S22). If operation B has not been received (NO in step S22), processor 150 repeats the process of step S22. When the operation B is received (YES in step S22), the processor 150 displays the control operation screen 330 on the display 158 (step S24).

Subsequently, the processor 150 determines whether or not an instruction input of a control operation is accepted via the input device 160 (step S26). When the instruction input of the control operation has not been received (NO in step S26), processor 150 repeats the process of step S26. When the instruction input of the control operation is received (YES in step S26), the processor 150 outputs a control operation signal corresponding to the control operation to the control target device X (step S28), and the process from step S10 is started. Repeat the process.

On the other hand, if the control operation is “impossible” in step S18 (NO in step S18), processor 150 causes display 158 to display determination result screen 310 indicating that the control operation is impossible (step S18). S30). Subsequently, the processor 150 determines whether or not the operation A (right-click operation on the device object 21) has been received from the user via the input device 160 (step S32). When the operation A is not accepted (NO in step S32), the processor 150 repeats the process of step S32. When the operation A is accepted (YES in step S32), the processor 150 displays the condition screen 320 including the interlock condition on the display 158 (step S34), and repeats the processing from step S10.

<Advantages>
According to the present embodiment, the user can know whether or not the control operation can be performed before performing the control operation on the desired control target device. If the control operation is not possible, the interlock condition can be displayed by a simple operation. Therefore, in order for the user to permit the control operation to the desired control target device, first, which control target It is possible to understand what kind of control operation should be performed on the device 2. Further, since the interlock determination is executed only for the control target device desired by the user, the processing load of the monitoring control device can be reduced.

In the case), the control operation screen 330 may be displayed only when the input of the operation B is received from the user.

Specifically, even if the monitoring control apparatus 100 receives the input of the operation B from the user in a state where the determination result screen 310 whose interlock determination result is “uncontrollable” is displayed, the monitoring control apparatus 100 performs the control operation. The screen 330 may not be displayed. According to this configuration, when the interlock determination result is “uncontrollable”, the control operation screen 330 is not displayed even if the user erroneously executes the operation B, so that the user performs unnecessary control operation. It is possible to reduce the possibility that it will occur.
