The own device operation information management unit 14 (first information acquisition unit) acquires and manages the own device operation information. Further, the own device operation information management unit 14 is connected to the own device operation information output unit 13 and the work procedure determination unit 16, and outputs the acquired own device operation information to the own device operation information output unit 13 and the work procedure determination unit 16. To do.

The other device operation information acquisition unit 15 (second information acquisition unit) is connected to the protection control device operation information output unit 3 in the monitoring terminal 1 via the local network 30. Then, the other device operation information acquisition unit 15 receives (acquires) the operation information (other device operation information) of the other protection control device collected by the monitoring terminal 1 via the local network 30. Further, the other device operation information acquisition unit 15 is connected to the work procedure determination unit 16 and outputs the acquired other device operation information to the work procedure determination unit 16.

The work procedure determination unit 16 (work determination unit) controls construction and maintenance based on the input own device operation information (first information), other device operation information (second information), and work procedure data. Determines if there is a work (operation) that can be performed next. Further, the work procedure determination unit 16 is connected to the operation command blocking unit 17, and outputs the determination result to the operation command blocking unit 17. At this time, when it is determined by the determination process by the work procedure determination unit 16 that there is an work that can be executed next, the work procedure determination unit 16 determines at least the information regarding the executable work (for example, the type of work). The determination result information including the identifiable information) is output to the operation command blocking unit 17.

On the other hand, when it is determined by the determination process by the work procedure determination unit 16 that there is no work that can be executed next, the work procedure determination unit 16 outputs information on the determination result including at least information indicating that there is no next operation. Output to the operation command blocking unit 17. Further, the work procedure determination unit 16 is connected to the display unit 20 (not shown), and when it is determined that there is no next work, the information of the determination result is output to the display unit 20. When the information of the determination result is input, the display unit 20 displays (notifies) information indicating that there is no work that can be executed next in the control such as construction and maintenance.

In the present embodiment, as described above, the work procedure determination unit 16 can perform the next work in the control of construction, maintenance, etc. based on the own device operation information, the other device operation information, and the work procedure data. Determine if there is. At this time, not only when there is no next work on the work procedure data, but also when there is the next work on the work procedure data, it depends on the operation information of other devices (operation status of other protection control devices). Therefore, it may be determined that there is no next work. For example, in the current operating status of another protection control device, when the next work is performed by the own protection control device 10, there is a problem in the work of itself and / or another protection control device (for example, the purpose of the work is achieved). If it is expected that the work cannot be completed, the work cannot be completed, etc.), it is determined that there is no next work.

The operation command cutoff unit 17 (operation command output control unit) is connected to the operation command input unit 21, the work procedure determination unit 16, and the electric power facility 31. The operation command blocking unit 17 determines whether or not the operation command is a valid command based on the operation command of the work input from the operation command input unit 21 and the information of the determination result input from the work procedure determination unit 16. Is determined.

Specifically, when the determination result information input from the work procedure determination unit 16 includes information on the next work, the operation command blocking unit 17 transmits the operation command input from the operation command input unit 21. It is acquired and it is determined whether or not the operation command is a command corresponding to the next work. Then, when the operation command is a command corresponding to the next work, the operation command blocking unit 17 determines that the operation command is a valid command, and determines that the operation command is an operation command (voltage signal corresponding to the operation command, etc.). Is output to the power equipment 31. As a result, in the control of construction and maintenance, predetermined work corresponding to the operation command is performed on the electric power facility 31.

On the other hand, when the operation command blocking unit 17 determines that the operation command input from the operation command input unit 21 is not a command corresponding to the next work, the operation command blocking unit 17 discards the operation command. As a result, the output of the operation command to the power equipment 31 is cut off. When the determination result information input from the work procedure determination unit 16 includes information indicating that there is no next operation (when there is no next operation), the operation command blocking unit 17 is the operation command input unit. The operation command is not acquired from 21, and the output of the operation command to the power equipment 31 is cut off.

Further, the operation command blocking unit 17 is connected to the display unit 20 (not shown), and when the operation command is discarded, the information indicating that the operation command is invalid is output to the display unit 20. When this information is input, the display unit 20 displays (notifies) information indicating that the operation command is invalid.

In addition to the OS (Operating System) and various parameters, the non-volatile storage C4 stores a program for causing the computer device C to function as the monitoring terminal 1 or the protection control device 10.

The network I / FC5 is composed of, for example, a NIC (Network Interface Card) or the like, and transmits and receives various data to and from each device connected via wireless communication.

The input device C6 is composed of, for example, keys and buttons, generates an operation signal according to the operation content input by the operator, and supplies the operation signal to the CPU C1. The display device C7 is composed of, for example, a liquid crystal panel or the like, and displays characters, images, and the like on the screen.

Depending on the configuration of the monitoring terminal 1 or the protection control device 10, the input device C6 or the display device C7 may not be provided. Further, when the protection control device 10 is provided with the input device C6 and the display device C7 as in the present embodiment, the operation command input unit 21, the operation authority input unit 22, and the work procedure data input unit 23 are input device C6. The display unit 20 may be configured by the display device C7.

When the monitoring terminal 1 is configured by the computer device C, each functional block unit in the monitoring terminal 1 shown in FIG. 1 is included in the CPU C1. Further, in this case, the monitoring terminal 1 transmits and receives operation information (own device operation information and other device operation information) to and from the protection control device 10 via the network I / FC5.

When the protection control device 10 is composed of the computer device C, each functional block unit in the protection control device 10 shown in FIG. 1 is included in the CPU C1. Therefore, the CPU C1 reads the program for operation monitoring processing stored in the ROM C2, and by executing the program, the function of each functional block unit is realized, and the work such as construction and maintenance for the electric power facility 31 is performed. Operation monitoring processing is performed.

At this time, the protection control device 10 transmits the operation information of the own device and receives the operation information of the other device with the monitoring terminal 1 via the network I / FC5. At this time, the protection control device 10 is connected to each external device (display unit 20, operation command input unit 21, operation authority input unit 22, work procedure data input unit 23, and electric power equipment via various interfaces (not shown). Input or output the corresponding data to and from 31). When the protection control device 10 and the power equipment 31 are connected by a communication line, the operation command is transmitted from the protection control device 10 to the power equipment 31 via the network I / FC5.

[Operation monitoring process]
Next, with reference to FIG. 3, for example, an operation monitoring process performed by the protection control device 10 during work such as periodic maintenance or construction of electric power equipment will be described. FIG. 3 is a flowchart showing the procedure of the operation monitoring process performed by the protection control device 10.

First, the protection control device 10 (operation authority authentication unit 11) acquires the authority information input to the operation authority input unit 22 by the operator (worker or the like) (step S1).

Next, the protection control device 10 (operation authority authentication unit 11) determines whether or not the operator is a person who has operation authority based on the acquired authority information (step S2).

In step S2, when the protection control device 10 determines that the operator is not a person who has the operation authority (NO determination in step S2), the protection control device 10 (operation authority authentication unit 11) determines the determination result. Output to the display unit 20 (step S3). By this process, information indicating that the operator does not have the operation authority is displayed (notified) on the display unit 20. Then, after the process of step S3, the protection control device 10 ends the operation monitoring process.

On the other hand, in step S2, when the protection control device 10 determines that the operator is a person who has the operation authority (when the determination in step S2 is YES), the protection control device 10 (operation authority authentication unit 11) has the authority. The information is input to the work procedure data authentication unit 12 (step S4).

Next, the protection control device 10 (work procedure data authentication unit 12) performs an activation process on the work procedure data acquired from the work procedure data input unit 23 (step S5). Further, in this process, the protection control device 10 (work procedure data authentication unit 12) outputs the activated work procedure data to the work procedure determination unit 16.

Next, the protection control device 10 (work procedure determination unit 16) has its own device operation information (various information regarding the operation status of its own protection control device 10) and other device operation information (other protections to be monitored by the monitoring terminal 1). (Various information regarding the operating status of the control device) is acquired (step S6).

Next, the protection control device 10 (work procedure determination unit 16) determines whether or not there is a work (operation) that can be executed next based on the acquired own device operation information, other device operation information, and work procedure data. (Step S7).

In the determination process of step S7, if there is no work that can be executed next on the work procedure data of the protection control device 10, the determination process of step S7 is a NO determination. In addition, even if there is a work that can be executed next on the work procedure data, when the work is executed, the self and / or other protection control is performed according to the current operating status of the other protection control device. Even when it is assumed that a problem will occur in the work of the apparatus, the determination process in step S7 is a NO determination. Therefore, when there is a work that can be executed next on the work procedure data of the user, and it is not expected that a problem will occur in the work of the user and / or other protection control device when the work is performed. The determination process in step S7 is a YES determination.

When the protection control device 10 determines in step S7 that there is no work that can be executed next (NO determination in step S7), the protection control device 10 (work procedure determination unit 16) displays the determination result. Output to unit 20 (step S8). By this process, information indicating that there is no work that can be executed next is displayed (notified) on the display unit 20. By notifying the information on the result of such a determination process on the display unit 20, the operator can be made to clearly recognize the presence or absence of the work that can be performed, and the operator's erroneous operation can be prevented more reliably. Can be done. Then, after the processing of step S8, the protection control device 10 returns the processing to step S6, and repeats the processing after step S6.

When the determination in step S7 is NO, the operation procedure determination unit 16 inputs the determination result information including the information indicating that there is no next operation to the operation command blocking unit 17. In this case, even if the operation command is input via the operation command input unit 21, the operation command blocking unit 17 does not acquire the operation command based on the information of the determination result. As a result, the output of the operation command to the electric power facility 31 is cut off.

On the other hand, when the protection control device 10 determines in step S7 that there is work that can be executed next (YES in step S7), the protection control device 10 (operation command blocking unit 17) inputs an operation command. The operation command input to the unit 21 is acquired (step S9). Further, in this process, the protection control device 10 (work procedure determination unit 16) outputs information on the determination result in step S7 (including information on the work that can be executed next) to the operation command blocking unit 17.

Next, the protection control device 10 (operation command blocking unit 17) determines whether or not the acquired operation command is a valid command based on the information of the determination result input from the work procedure determination unit 16 (step). S10). In the determination process of step S10, for example, it is determined whether or not the operation command corresponding to the information related to the next work included in the determination result information is the operation command input to the operation command input unit 21. Then, if both match, it is determined that the operation command is a valid command, and the determination process in step S10 is a YES determination.

If the protection control device 10 determines in step S10 that the operation command is not a valid command (NO determination in step S10), the protection control device 10 (operation command blocking unit 17) discards the operation command (when the operation command is determined to be NO). Step S11). As a result, the output of the operation command to the electric power facility 31 is cut off. That is, in the present embodiment, as described above, the operation command blocking function can be operated in two steps, one when step S7 is NO determination and the other when step S10 is NO determination, and the operator's erroneous operation is further prevented. It can be reliably prevented.

Next, the protection control device 10 (operation command blocking unit 17) outputs information (determination result in step S10) indicating that the operation command is invalid to the display unit 20 (step S12). By this process, information indicating that the operation command is invalid is displayed (notified) on the display unit 20. By notifying the display unit 20 of the information regarding the result of such a determination process, the operator can be made to clearly recognize the validity / invalidity of the operation, and the operator can be given a valid (legitimate) operation command. You can be prompted for input. As a result, erroneous operation by the operator can be prevented more reliably. Then, after the processing of step S12, the protection control device 10 returns the processing to step S9, and repeats the processing after step S9.

On the other hand, in step S10, when the protection control device 10 determines that the operation command is a valid command (when the determination in step S10 is YES), the protection control device 10 (operation command blocking unit 17) issues an operation command. Output to the power equipment 31 (step S13). By this process, a predetermined operation corresponding to the operation command input by the operator is executed on the electric power facility 31.

Next, the protection control device 10 (work procedure determination unit 16) determines whether or not there is a next procedure in work such as maintenance or construction according to the procedure manual currently being executed (step S14). This determination process is performed with reference to the input work procedure data.

When the protection control device 10 determines in step S14 that there is a next procedure (when the determination in step S14 is YES), the protection control device 10 returns the process to step S6 and repeats the processes after step S6. That is, the processes after step S6 are repeated until all the work procedures defined in the currently input work procedure data are completed.

On the other hand, if the protection control device 10 determines in step S14 that there is no next procedure (NO determination in step S14), the protection control device 10 ends the operation monitoring process. In the present embodiment, as described above, monitoring processing of the direct operation of the operator in work such as maintenance or construction of, for example, electric power equipment is performed.

[effect]
As described above, in the protection control device 10 of the present embodiment and its operation monitoring process, only an operator (worker or the like) having an operation authority executes work such as maintenance or construction on the corresponding electric power facility 31. can do. Further, at this time, is the operation to be executed effective in consideration of not only the work procedure data of the work performed by the own protection control device 10 and its own operation status but also the operation status of other protection control devices? Judge whether or not. Then, only when it is determined that the operation to be executed is valid, the work corresponding to the operation is executed for the electric power facility 31.

Further, in the present embodiment, even if an operation command is input by an operator having operation authority, it is assumed that a problem will occur in processing by itself and / or another protection control device when the next operation is executed. If so, the operation command is determined to be invalid. That is, in the protection control device 10 of the present embodiment, even if an operation command is input by an operator having operation authority, the operation command is invalid depending on the operation status of itself and / or another protection control device. If so, the operation command is automatically blocked (locked). Therefore, in the present embodiment, for example, even if work such as construction or maintenance over the entire system including a plurality of devices (electric power equipment, etc.) is executed, the risk of erroneous operation of the work on the equipment in charge of the worker is increased. It can be further reduced.

[Various variants]
Although the operation monitoring method of the protection control device 10, the protection control system 100, and the protection control device 10 according to the embodiment of the present invention has been described above, the present invention is not limited to the above embodiment. The configuration of the present invention may be configured as various other modifications and applications as long as it does not deviate from the gist of the present invention described in the claims. For example, the following various modifications are also included in the present invention.

In the protection control system 100 of the above embodiment (configuration example shown in FIG. 1), an example in which the processing functions of various functional blocks included in each device are realized by software in each of the monitoring terminal 1 and the protection control device 10 will be described. However, the present invention is not limited to this. A part or all of these functional blocks may be configured by hardware.

In the protection control system 100 of the above embodiment, an example in which the protection control device 10 acquires the operation information of the other device (operation information of the other protection control device) via the monitoring terminal 1 has been described. Not limited to. For example, the protection control device 10 may be configured to directly acquire the operation information of the other device from the other protection control device via the local network 30 without going through the monitoring terminal 1. In this case, since it is not necessary to provide the protection control device operation information output unit 3 in the monitoring terminal 1, the configuration of the protection control system 100 can be simplified.

In the protection control device 10 of the above embodiment, a configuration for determining whether or not the input operation command is a command by an operator (worker or the like) having an operation authority, that is, a configuration for always determining the presence or absence of the operation authority. However, the present invention is not limited to this. For example, the configuration may be such that the presence or absence of operation authority is not determined according to the work content and the like.

Further, in the protection control device 10 of the above embodiment, the operation command blocking unit 17 is effective for the operation command based on the operation command input by the operator and the information of the determination result in the work procedure determination unit 16. Although an example of determining whether or not it is a directive has been described, the present invention is not limited to this. For example, the operation command blocking unit 17 may be configured to determine whether or not the operation command input by the operator is a valid command based on the own device operation information, other device operation information, and work procedure data.
