Description

  The present disclosure relates to a monitoring control device for monitoring and controlling monitoring target devices in a power system.

  Conventionally, when a monitoring control device (system) controls a plurality of devices to be monitored and controlled, the interlock conditions set for each device to be monitored and controlled (other monitoring and control target devices related to the monitoring and control target device, alarms, etc.) In the case where the determination result is “impossible control operation”, the control is blocked.

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

  In the display method of the monitoring control system according to Japanese Patent Application Laid-Open No. 2008-123427 (Patent Document 2), the 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 interlock determination result is displayed on the displayed screen.

JP 2001-142527 A JP 2008-123427 A

  However, according to the technique according to Patent Literature 1, since the interlock determination is executed only when the operator performs a control operation on the monitoring control target device, the interlock determination result is “uncontrollable operation”. In other words, the operator has performed unnecessary and unnecessary control operations.

  In addition, according to the technique according to Patent Document 2, by performing an interlock determination periodically or when input information changes, independently of the control operation, the “control operation impossible” device can be obtained. The useless operation of executing the control operation is eliminated. However, there is a problem that the processing load of the monitoring control system increases when many monitoring control target devices are provided in the power system or when the state of the monitoring control target devices frequently changes. .

  The present disclosure has been made in view of the above-described problems, and an object in one aspect is to make it unnecessary for the user to perform a wasteful control operation and reduce the processing load. It is to provide a monitoring control device.

  A monitoring control device according to an embodiment includes a system display processing unit that displays a system screen for a power system to which a plurality of control target devices are connected, on a display, based on state information of the plurality of control target devices, and a plurality of An interlock determination unit that determines whether or not the control operation of each control target device is possible based on the state information of the control target device. When receiving a designation operation for designating a control target device on the system screen, the interlock determination unit determines whether the control operation of the designated control target device is possible. The monitoring control apparatus further includes a result display processing unit that displays the determination result of the interlock determination unit on the display. The result display processing unit displays a condition screen including an interlock condition used for determining whether or not the control operation of the specified control target device is possible when the first operation is received in a state where the determination result is displayed. To display.

  According to the present disclosure, it is possible to reduce the processing load while preventing the user from performing unnecessary control operations.

<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 control target device 2. First, a display method of the monitoring control screen when the monitoring control apparatus 100 is set to the normal control mode will be described.

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

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

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

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

  The system screen 300 is configured to change the color of each corresponding device object in accordance with the open / closed state of each control target device 2. For example, when the control target device 2 is in the open state, the color of the corresponding device object is expressed as black (for example, the device object 23), and when the control target device 2 is in the closed state, the color of the device object is white (for example, the device object). 11-13, 21, 22). The system screen 300 may be configured such that the open / close state of the control target device 2 can be determined by other display methods. For example, the size of the device object may be changed according to the open / closed state, or a word 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 superimpose the pointer 50 on the device object 21, an interlock determination result screen 310 is displayed. It is displayed on the screen 300. Specifically, when receiving an operation input in which 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. 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 the control target device based on the interlock condition stored in the secondary storage device 154 or the like. It is determined whether or not a control operation for bringing the device 2 into the “open state” is possible.

  In the example of FIG. 4, it is determined that the control operation of the control target device 2 is impossible (prohibited), and a determination result screen 310 showing the determination result is displayed. When it is determined that the control operation of the control target device 2 is permitted (permitted), a determination result screen 310 indicating that is displayed. Thereby, the user can grasp | ascertain the propriety of the said control operation, before performing control operation to the desired control object apparatus 2. FIG.

  Subsequently, referring to FIG. 5, a specific operation A (for example, a user's operation) (for example, a state in which the pointer 50 is superimposed on the device object 21) in a state where the determination result screen 310 is displayed as illustrated in FIG. 4. When the input of (right click operation) is received, a condition screen 320 including an interlock condition 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 also be referred to as “control target device X”.

  The condition screen 320 includes a status column 322 indicating the open / closed state of the control target device X (“closed state” in the example of FIG. 5), a result column 324 indicating the determination result, and whether or not the control operation of the control target device 2 is permitted. And a condition column 326 indicating an interlock condition used for the determination. Specifically, the condition column 326 indicates a condition for permitting a control operation (open operation) for opening the control target device 2. Typically, when any of the conditions (1), (2), and (3) in the condition column 326 is satisfied, the interlock condition is satisfied. Condition (1) is satisfied when the control target device 2 corresponding to the label “CB1” is in the open state. Condition (2) is satisfied when each control target device 2 corresponding to the labels “CB2” and “CB3” is in the open state. Condition (3) is satisfied when the control target device 2 corresponding to the label “CB2” is in the open state and the control target device 2 corresponding to the label “LS3” is in the closed state. As a result, the user can first know what control operation needs to be performed on which control target device 2 in order for the control operation to the desired control target device 2 to be permitted.

  Subsequently, with reference to FIG. 6, when the monitoring control apparatus 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 apparatus 100 A control operation screen 330 for executing the control operation is displayed on the system screen 300. Note that the monitoring control apparatus 100 may be configured to display the control operation screen 330 on the system screen 300 when the input of the operation B is received from the user while the determination result screen 310 is displayed.

  The control operation screen 330 displays a column 332 indicating a control target device 2 (control target device X in the example of FIG. 6) that is a target for outputting a control operation signal, and a control operation for closing the control target device X. A closed button 334 to be received, an open button 336 for receiving a control operation for opening the control target device X, and a control operation signal corresponding to the control operation received by the close button 334 or the open button 336 to the control target device X. And an output button 338 for outputting. For example, the user can output an open operation signal to the control target device X by selecting the output button 338 after selecting (for example, pressing) the open button 336.

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

  The user confirms the determination result screen 310 displayed on the system screen 300, and when the determination result is “controllable”, the user performs the operation B (left click operation) to display the control operation screen 330 (FIG. 6). Then, the user can output a control operation signal to the desired control target device 2 by selecting the close button 334 or the open button 336 on 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 when the determination result is “uncontrollable”, the user performs operation A (right click operation) to display the condition screen 320 (see FIG. 5). The user confirms the condition screen 320 and identifies which control target device 2 needs to be opened or closed. The user moves the pointer 50 so as to overlap the device object corresponding to the specified control target device 2 and repeats the above operation.

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

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

  Similarly to the above-described normal control mode, when the monitoring control apparatus 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 target device 2 corresponding to the device object can be controlled. The determination is executed and the determination 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. A condition screen 320 </ b> A is displayed on the system screen 300. The system screen 300 displays mode information 350 indicating that the emergency control mode is being performed.

  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 receiving an operation for invalidating the corresponding interlock condition.

  Here, for example, the user understands that an emergency situation has occurred and the status information of the label “CB3” has not been properly acquired (the status information is incorrect or the status information cannot be received, etc.) Suppose you are in a situation. In this case, as shown in FIG. 8, in order to invalidate the interlock condition for the label “CB3”, the user moves the pointer 50 and checks the check box disposed on the right side of the label “CB3” in the condition column 326A. Select. Accordingly, the interlock condition regarding the label “CB3” can be invalidated, and therefore the condition (2) is satisfied when the control target device 2 corresponding to the label “CB2” is in the open state.

  When the user moves the pointer 50 so as to overlap the device object 21 on the system screen 300 after selecting the check box, the monitoring control apparatus 100 ignores the interlock condition related to the label “CB3” and The lock determination is executed, and the determination result screen 310 is displayed.

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

<Functional configuration>
FIG. 9 is a schematic diagram illustrating a functional configuration of the monitoring control device 100. Referring to FIG. 9, monitoring control apparatus 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 by the processor 150 executing a program stored in the secondary storage device 154, for example. The monitoring control apparatus 100 further includes a state information storage unit 203 and a condition information storage unit 209 realized by the main storage device 152 and the secondary storage device 154. Note that some or all of these functions may be implemented 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 / close state, and may include type information, identification information, and the like of the control target device 2.

  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 the control target device 2 can be controlled based on the interlock condition stored in the condition information storage unit 209 and the status information of the control target device 2. Specifically, when the operation input unit 205 receives a designation operation for designating the control target device 2 on the system screen 300, the interlock determination unit 207 performs the control operation for the designated control target device 2. Determine whether it is possible. The designation operation includes an operation of superimposing the pointer 50 indicating the user's operation position 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 performing mode setting. 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 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.

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

  The determination result display processing unit 224 causes the display 158 to display an interlock determination result (for example, the determination result screen 310). In addition, the determination result display processing unit 224 displays the control operation of the designated control target device 2 when the operation input unit 205 receives a specific operation (for example, operation A) in a state where the determination result is displayed. A condition screen 320 including the interlock condition used for the determination of availability 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 received in a state where a determination result indicating that the control operation of the designated control target device 2 is not possible is displayed. Let

  When the monitoring control apparatus 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, check box group 327) for receiving the operation to be displayed is further displayed. In this case, when the operation input unit 205 receives a selection operation on the object, the interlock determination unit 207 uses the remaining interlock conditions other than the interlock condition corresponding to the selected object to control the target device. Whether or not the second control operation 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 displays a control operation screen 330 for executing a control operation of the control target device 2 on the display 158. Specifically, the control operation display processing unit 226 displays the determination result indicating that the control operation can be performed by the determination result display processing unit 224 on the display 158, and the operation input unit 205 performs a 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 apparatus 100. Here, a flow until the user executes a control operation (for example, “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. . Typically, each step shown in FIG. 10 is executed by the processor 150. It is assumed that the processor 150 periodically acquires the status information of the control target device 2 via the communication interface 156.

  Referring to FIG. 10, processor 150 displays, on display 158, grid screen 300 that is an overall diagram of the power grid based on the status information of control target device 2 (step S <b> 10). The processor 150 receives an operation input from the user via the input device 160, and determines whether or not the pointer 50 is superimposed on any of the device objects 11 to 13 and 21 to 23 on the system screen 300 (step S12). ).

  If the pointer 50 is not superimposed on the device object (NO in step S12), the process in step S12 is repeated. When the pointer 50 is superimposed on any device object (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 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 status information of each control target device 2 necessary for determining whether 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 control target device X is possible based on the read interlock condition and the state information of each control target 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 (close operation) for closing the control target device X is possible. In the closed state, it is determined whether or not a control operation (open operation) for opening the control target device X is possible.

  If the control operation is “permitted” (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) is 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 in step S22. When operation B is accepted (YES in step S22), processor 150 displays control operation screen 330 on display 158 (step S24).

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

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

<Advantages>
According to the present embodiment, the user can grasp whether or not the control operation is possible before executing the control operation on the desired control target device. In addition, when the control operation is impossible, the interlock condition can be displayed by a simple operation. It is possible to grasp what kind of control operation needs to 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.

Although the configuration has been described, the configuration is not limited thereto. For example, the monitoring control device 100 is configured to display the determination result screen 310, the condition screen 320, and the control operation screen 330 independently, such as in a separate window, without displaying them on the system screen 300. Also good.

  (3) In the above-described embodiment, the monitoring control apparatus 100 has basically been described with respect to the configuration in which the control operation screen 330 is displayed when the input of the operation B is received from the user. Not limited. For example, the monitoring control apparatus 100 determines that the control operation of the control target device 2 is possible in a state where the determination result screen 310 whose interlock determination result is “controllable” is displayed. The control operation screen 330 may be displayed only when the input of the operation B is received from the user.

  Specifically, the monitoring and control apparatus 100 controls the control operation even when the input of the operation B is received from the user while the determination result screen 310 with the interlock determination result “uncontrollable” is displayed. 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 when the user mistakenly executes the operation B. It is possible to reduce the possibility of being executed.

  (4) The configuration exemplified as the above-described embodiment is an example of the configuration of the present invention, and can be combined with another known technique, and a part thereof does not depart from the gist of the present invention. It is also possible to change and configure such as omitting. In the above-described embodiment, the process and configuration described in the other embodiments may be adopted as appropriate.

  The embodiment disclosed this time should be considered as illustrative in all points and not restrictive. The scope of the present invention is defined by the terms of the claims, rather than the description above, and is intended to include any modifications within the scope and meaning equivalent to the terms of the claims.
