Software etc. are memorized.

  Next, among the information distribution / analysis screen creation unit 24 of the analysis screen creation support apparatus 2 as described above, a series of processing operations of the screen creation support processing unit 24b in particular will be described.

  Here, as an example, an example of creating an analysis screen for analyzing the operation content of the device “52R (power receiving AC circuit breaker)” will be described with reference to FIGS. 4 and 5.

  When receiving the analysis screen creation instruction from the input unit 21 (S1), the screen creation support processing unit 24b executes the analysis target specifying unit 24b-1 according to the analysis screen creation software.

  The analysis target specifying unit 24b-1 displays the preset registration screen 100 on the display unit 27 (S2). It is determined whether an instruction of the target device to be analyzed is input from the input unit 21 (S3). Here, when the device information “52R” is directly input from the input unit 21, or is input by clicking selection from the analysis target device “52R” stored in the device information storage unit 25-2, there is an instruction of the analysis target device. And the analysis target device is specified.

  When the screen creation support processing unit 24b specifies the analysis target device, the screen creation support processing unit 24b executes the device information arrangement unit 24b-2 to create the analysis screen 101. That is, the device information arrangement unit 24b-2 places the symbol mark 102 with a character 102 and the vicinity thereof on the registration screen 100 based on the coordinate position corresponding to the device “52R” of the device ID defined in the information management table 25a, for example. The time data 103 of on / off collection information is arranged from the device information storage unit 25-2 (S4).

  The user drags the symbol mark 102 with characters and the time data 103 by the input unit 21 to arbitrarily change the arrangement position. For the symbol mark 102, for example, an appropriate component can be obtained from the palette data storage unit 25-7. It is also possible to select and set a symbol mark.

  Further, the screen creation support processing unit 24b selects the measurement information storage unit 25-5 based on, for example, selection of the selection message, and measures the time related to the event occurrence of the corresponding device “52R” and the measurement related to the corresponding device “52R”.

The contact information display unit 105 with the symbol marks is arranged (S6).

  As for how many auxiliary relays are connected between the corresponding operation device 11 that outputs the operation information described later and the corresponding device “52R”, for example, a system screen simulating a power system diagram was created. Since the storage device 25 stores the basic file data or the data of the development connection diagram of the sequence processing relating to the device group including the number of auxiliary relays that are the monitoring target devices 15 housed in the switchboard for monitoring the power system, Based on this information, symbol marks of on / off contact information of a plurality of monitoring target devices 15 such as auxiliary relays may be sequentially connected and arranged. Further, the user may select and set an appropriate mark from symbol marks of appropriate parts stored in the palette data storage unit 25-7 from the input unit 21.

  In addition, when color data is set in the information management table 25a or the pallet data storage unit 25-7, for example, red when the device is turned on and green when the device is turned off, the symbol mark is displayed when the monitored device 15 is turned on. The color of can be automatically set from green to red. Furthermore, it is also possible to arrange time data when each monitored device 15 is turned on in the vicinity of the symbol mark representing the contact information.

  Finally, the screen creation support processing unit 24b, for example, from the operation information storage unit 25-3 and the accident information storage unit 25-1 for storing the trip operation factor, the operation information serving as the trigger factor, and the accident information for the corresponding device “52R”. Based on the coordinate position corresponding to the device ID of the device that reads the operation information and accident information corresponding to the device “52R” and outputs the operation information and accident information registered in the information management table 25a in the registration screen 100, The operation information display unit 106 for the symbol mark with characters is arranged (S7). At this time, time data 107 at the time of operation may be arranged. In FIG. 5, 50R is a power receiving overcurrent protection relay which is an accident detection device.

  Note that the user selects and sets a symbol mark of an appropriate part from the pallet data storage unit 25-7 using the input unit 21, or determines whether or not an operation is stored in the information management table 25a or the pallet data storage unit 25-7. The time when the color change, trip action factor, or trigger factor occurs may be arranged according to the corresponding color data.

  Further, based on an instruction from the input unit 21 by the user, it is also possible to arrange the line segment connecting each symbol, the direction of the arrow 108, and the like as appropriate.

  When the analysis screen 101 for analyzing the operation content of the device “52R” is created as described above, the analysis screen 101 of the device “52R” is stored in the screen data storage unit 25-6 (S8), and then the screen is displayed. The list creation / registration means 24b-3 is executed. The screen list creation / registration unit 24b-3 creates an analysis screen registration list 109 for linking with the analysis screen 101 of the corresponding device “52R” stored in the screen data storage unit 25-6, and stores it in an appropriate storage unit. (S9).

  As a result, the analysis screen registration list 109 is displayed later, the device “52R” analysis is selected from the list 109, and the analysis screen 101 of the device “52R” stored in the screen data storage unit 25-6 is read and displayed. By doing so, changes such as rearrangement of parts in the analysis screen 101 can be made relatively easily by editing.

  In addition to the device “52R”, the analysis screen registration list 109 registers an analysis list such as the device “52F (feeding AC circuit breaker)” and the device “52D (high voltage distribution AC circuit breaker)”. Yes.

  Next, FIG. 6 is a diagram for explaining an example of a call display on the analysis screen.

  First, a history screen 201 and a system screen 202 simulating a power system diagram have been conventionally displayed on the display unit of the monitoring device, and an accident analysis of the power system has been performed. These history screen 201 and system screen 202 have various locations. Device name, for example, device “52R” exists.

  On the other hand, in the present embodiment, as shown in FIG. 5, an analysis screen 101 for newly analyzing the operation content of the device “52R (power-receiving AC circuit breaker)” is created. A list 109 is created and stored in appropriate storage means.

  Therefore, it is possible to link a device such as the device “52R” existing in the history screen 201 and the system screen 202 with the registration screen 100 or the analysis screen 101.

  As a result, if the device “52R” is clicked in the history screen 201 or the system screen 202 that has been created conventionally with the mouse constituting the input unit 21 as well as the analysis screen registration list 109, the device “52R” is clicked. Can be displayed on the display unit 27.

  Further, FIG. 7 is a diagram illustrating a typical example at the time of event analysis of the device “52R”, using the analysis screen 101 displayed on the display unit 27.

  In this example, the device “52R” is selected from any of the history screen 201, the system screen 202, and the analysis screen registration list 109, and the analysis screen 101 related to the device “52R” is displayed on the display unit 27.

  In this state, if a time traced back to the past from the input unit 21 is input and set, event-changed operation information stored in the operation information storage unit 25-3 after that time, for example, a remote operation is performed. The time data 301 and the symbol mark of the remote operation whose color has changed (black square) at that time are displayed.

  Further, after the color change (black square) due to the remote operation, the contact information such as the auxiliary relay connected to the remote controller stored in the contact information storage unit 25-4 in time series is changed, for example, by turning on with the passage of time (e.g. The various measurement information stored in the black circle) and the measurement information storage unit 25-5 change. Accordingly, the contact information (color change) 302 and the measurement information 303 on the analysis screen 101 change with the change of time. That is, it is possible to display the analysis screen 101 with a state change for each time.

  The analysis screen 101 can also display time data 301 and 304 whose events have changed in time series.

  As a result, the operation content of the device “52R” and the change state of the event can be analyzed from the state change of each device displayed on the analysis screen 101, and a more appropriate analysis result can be obtained.

  For example, when the analysis screen 101 is called from the history screen 201 and selected, an analysis screen 101 ′ with a change in state of the selected history time different from the analysis screen 101 can be displayed.

  Furthermore, when the analysis screen 101 is called and selected from the system screen 202 and the analysis screen registration list 109, the analysis state of the analysis screen 101 ′ at the time of the call can be displayed.

  In any call of the history screen 20, the system screen 202, and the analysis screen registration list 109, it is possible to display the analysis result information at an arbitrary time retroactively.

  Therefore, according to the embodiment as described above, information necessary for event analysis (contact information and measurement information) is newly collected on an existing screen, and a new screen is additionally arranged to capture a visual event change. It is possible to quickly grasp the system status.

  Further, according to the user's intention, the state of the event change of the related device including the monitoring target device can be tracked and displayed as needed, and an appropriate analysis result can be obtained from the event change of the related device corresponding to the monitoring target device.

  Further, when the user sets the time retroactively and selects the monitoring target device, an analysis screen related to the monitoring target device at the time can be quickly displayed on the display unit 27, and the operation state of the monitoring target device can be quickly displayed. Can be analyzed.

  Furthermore, if the color data of the symbol is changed when the event of each device changes, the state change of each device can be grasped instantaneously.

  Furthermore, by displaying a list of various events related to the device to be analyzed as shown in FIG. 5, it is possible to investigate in detail the contents that could not be analyzed so far.

  In the above embodiment, the collected information is arranged according to the processing procedure shown in FIG. 4, but the order of the information arrangement in steps S5 to S7 is not particularly limited.
