Description

  The present invention relates to a technique for supporting creation of a program for a digital protection control apparatus.

  As shown in FIG. 5, the program of the digital protection control apparatus for protecting the power system includes a plurality of basic part programs PA, PB, PC, and a plurality of setting data SA1, SA2 for controlling the execution thereof. .., And each of these setting data constitutes a program of the digital protection control device together with each basic part program.

  Of these, the basic part program, which is the basic part, is configured to execute processing according to the contents of the corresponding setting data, such as a monitoring module, an inspection module, an apparatus operation module, a screen control module, a relay operation module, etc. It is a so-called core program, and once it is produced and the function inspection is completed, almost no changes occur except for function improvement.

  On the other hand, setting data gives setting values, setting values, and the like to the modules of the basic program, and includes programs automatically generated from sequence logic.

  This setting data can be obtained from the individual requirement specifications on the side that uses the protection control device, the rating information of the current transformer (CT), transformer (VT), etc. used in the system, or for power transmission line protection, bus protection, etc. If the model is different, change the settings.

  As a conventional work procedure in creating such a program, as a first step, a production specification of the program is created mainly referring to a development connection diagram (also referred to as a logic sequence diagram), and the program, In particular, it expands to setting data.

  Conventionally, there are tools to create setting data and a part of the program, but the function was thought by humans based on the human reference to the contents and program production specifications described in the development connection diagram. It was such that it accepts manual input of setting data and reflects it to generate a program (see Patent Document 1).

  In addition, an automatic software generation tool for the sequence logic unit described in the developed connection diagram has existed in the past, but only generates a part of the program in the specific CPU of the protection control device (patent) Reference 2).

  In this way, when making production specifications with reference to the development connection diagram, and also when creating setting data from production specifications, we have relied on human input, but if human errors such as input errors occur In some cases, the operation responsibility of the protection control device may be affected, and the programs of the digital protection control device are made plural and complicated.

For this reason, conventionally, a lot of time has been spent on confirming the validity after setting data is input. At this time, a lot of setting data is described in the expanded connection diagram that describes the protection method and system configuration of the protection control device and the response of the device. We have collated with the figure.
JP-A-2005-354857 Special No. 2519250

  As described above, in the past, most of the setting data was created manually by humans, and furthermore, in order to prevent erroneous settings, a lot of time was spent on validity verification after setting, so the efficiency There was a need for chemistry.

  In addition, even in the stage of creating production specifications prior to them, duplicate work such as inputting the same content multiple times occurs, and if a mistake in transcription, incorrect input, or an error due to the designer's assumption occurs, the completed program will be It was also a problem that it might not match the contents of the expanded connection diagram.

  In recent years, a dedicated CAD tool has been adopted to create a development connection diagram, and the contents described in the development connection diagram can be extracted as data. There has never been a technology that effectively uses data.

  The present invention solves the conventional problems as described above, and its purpose is to greatly improve the setting data constituting the program of the digital protection control apparatus by automating the generation of information by extracting information from the developed connection diagram. It is to reduce the burden. Another object of the present invention is to automate the validation of such work.

  In order to achieve the above object, according to one aspect of the present invention, in a program generation device that generates at least setting data among programs of a digital protection control device, predetermined information is extracted from a development connection diagram of the protection control device. Using the extracted information, construction means for constructing a database for setting data generation, generation means for automatically generating the setting data of the protection control device based on the database, Is realized by an arithmetic control unit of a computer.

  As described above, according to the present invention, it is not necessary to create a program production specification by automatically generating a database that plays the role of a program production specification based on the contents described in the development connection diagram. Business efficiency improves, such as saving. Furthermore, by automatically generating the setting data based on the database, there is no inconsistency among the developed connection diagram, the database, and the setting data, and the reliability of the program is improved.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS The best mode for carrying out the present invention will be described below with reference to the drawings. Note that assumptions common to the explanation in the background art and problems are omitted as appropriate.

[1. Constitution〕
The present embodiment relates to an automatic program generation device (hereinafter referred to as “this device”) that generates at least setting data among programs of a digital protection control device (also simply referred to as “protection control device”). Is realized by each of the elements 40 to 47 shown in the block diagram of FIG. Each of these elements is processing means for realizing and executing the functions of the following functions in the present invention and this embodiment.

[2. Outline of action)
Next, a processing procedure for creating a program centering on setting data in the present embodiment is shown in the flowchart of FIG. As an outline, based on the development connection diagram D1 that represents the digital protection control device to be programmed as a sequence, the extraction means 40 is required to use a predetermined, ie, predetermined type of information required for the setting data. Is extracted (step S01), and using the extracted information, the construction means 41 constructs the setting data generation database D2 (step S03). After that, based on this database D2, the setting data generation means 42 automates the operations until the setting data S is generated (step S07) and integrated with the basic program (step S09).

In the present embodiment, when the database D2 is constructed by the construction unit 41 and when the setting data S is generated by the generation unit 42, the first confirmation unit 43 and the second confirmation unit that are rationality confirmation units are used. The means 44 confirms the rationality according to the rules inputted in advance.
Hereinafter, each step will be described in detail.

[3. Database creation)
First, FIG. 3 shows an example in which a digital protection relay device is taken as an example, and the setting of the relay element is described in the developed connection diagram. FIG. 4 schematically shows an operation screen of a program (setting data automatic creation tool, also simply referred to as “this tool”) that realizes a function for automatically generating setting data in the apparatus.

  In other words, when creating a development connection diagram using an arbitrary drawing tool such as CAD, the information and characters necessary for the setting data are dedicated to the setting contents prepared in advance so that this tool can automatically extract them. Information component 32 (FIG. 3). This information component corresponds to an actual component constituting the digital type protective relay device, and is a combination of predetermined items such as a setting range and a step, and is identified by an element name or an identification ID. Incidentally, the element names 44SX1 to 44SX3 mean the first to third stages of the short-circuit distance relay.

  Then, on the operation screen (FIG. 4), when the push button “data read” (51), which is the screen GUI element, is selected for the expanded connection diagram that is the target of data extraction, the extracting means 40 displays the expanded connection diagram D1. All the predetermined information is extracted from the information components as described above (step S01), and functions such as set values, setting values, test settings, automatic monitoring settings necessary for generating the protection control device program, that is, for each use Then, a database D2 containing the extracted predetermined values is created (step S03).

  Here, in order to display the contents of each database, a corresponding item is selected from the selection items A to H shown in the selection column 54. For example, the item “A” is assigned as “setting value”. It should be noted that although it is a content that does not need to be displayed in the development connection diagram, information necessary for the setting data is included as an attribute in the drawing component, and such information is also simultaneously developed in the data display area 55 when the database is created. For example, for the set value, information such as “offset” stored in the program is set in the display area 55 of FIG. 4, but these are contents that are not required to be displayed in the developed connection diagram (FIG. 3). It corresponds to.

[4. Check rationality when creating database)
In addition, when generating the database D2 from the expanded connection diagram D1 as described above, the first confirmation unit 43 performs a check for missing or inappropriate description (first rationality check) for the expanded connection diagram D1. Perform (step S02). As a check rule, an absolute value check rule R11 based on an absolute value and a relative value check rule R12 based on a relative value are prepared in a predetermined storage area in advance.

  The former for the absolute value is for confirming whether each data is a value within the limit for each data item included in the development connection diagram D1. The latter with respect to the relative value means whether or not the relative value defined in the rule is satisfied in the correlation with other data, not with individual data items alone. In accordance with these rules, the validity of the original expanded connection diagram D1 is confirmed (step S02), and the database D2 is created (step S03).

  For example, the setting value shown in FIG. 3 will be described as an example. When a value other than a numerical value such as an element name of a character string is entered in the “maximum” item, as an absolute value check, and “maximum” If the “minimum” data is reversed, a rule violation error warning is output as a relative value check.

[5. Generation of setting data)
After the database D2 for each function is generated as described above, when the “Reflect” (52) selection operation is performed on the operation screen (FIG. 4), the generation unit 42 sets necessary settings for the program based on the database D2. Data S is generated (step S07). Here, when there are a plurality of CPUs in the protection control device (so-called multi-CPU), the generation means 42 generates the setting data S while distributing the setting data S to the units of functions handled by the individual CPUs.

  In the generation of the setting data S, based on the functions included in the database D2, that is, the individual values for each element, the basic part program inputs the values from which input channel, for example, alone or in any combination. Alternatively, the generation unit 46 configures the setting data S by a determination process such as from which output channel the data is output or a reference value for condition determination.

[6. Check rationality when generating setting data)
Further, when the setting data S is generated from the database D2 as described above, the second confirmation unit 44 determines whether there is an inappropriate input in the database D2, and the absolute value check rule R21 and the relative value check rule R22. The second rationality check by the absolute value and the relative value is performed according to (Step S04), and the validity of the setting data is ensured. When the second rationality check is passed, the database creation is considered to be officially completed (step S06).

  The rules R21 and R22 may be the same as the rules R11 and R12 at the time of creating the database or may be completely different, but it is desirable to implement the rules so that the user can make additional changes as necessary. .

  As described above, rationality based on rules prepared in advance, that is, validation of validity, it becomes possible not only to improve the efficiency of creation of setting data that forms part of the program, but also to eliminate human check omissions, Reliability can be further improved.

  The generated setting data S is copied to a predetermined area of the program creation environment such as an appropriate management tool when the “copy” (53) operation is performed on the operation screen (FIG. 4). Is integrated with the basic program in such a creation environment, the final target program is completed.

[7. (Reflect to development connection diagram)
In addition, when the database D2 is added and modified, the reflecting unit 45 reflects the contents on the corresponding developed connection diagram D1. Specifically, for example, when generating the database D2 from the expanded connection diagram D1, each element in the expanded connection diagram D1 and each element in the database D2 are linked by identification information such as the element name and ID, and the database Updates such as additions and modifications made to the elements in D2 are reflected in the elements in the original development connection diagram D1 based on the link.

  In this way, the process of reflecting the update in the contents of the database D2 to the expanded connection diagram D1 may be instructed by some other operation. Preferably, for example, the database extracted and generated from the expanded connection diagram D1 is used. For D2, when “Reflect” (52) of this tool as shown in FIG. 4 is selected, not only the setting data S is generated based on the contents of the database D2, but also at the same time by the reflecting means 45, This is also reflected in the original development connection diagram D1.

  As a result, even if the database D2 is corrected as a result of the rationality check, it can be reflected in the expanded connection diagram D1 only by correcting the database D2 without returning to the procedure for correcting the expanded connection diagram D1. Matching is also ensured between the generated setting data S and the development connection diagram D1, and contradiction from the development connection diagram D1 to the programs P1 and P2 is eliminated, and unified management becomes easy.

[8. effect〕
As described above, according to the present embodiment, the trouble of creating the program production specification by automatically generating the database D2 that plays the role of the program production specification based on the contents described in the development connection diagram D1. In addition, the operational efficiency is improved, and the database D2 matches the development connection diagram D1, so that the finally obtained setting data S and the reliability of the program in which it is incorporated are also improved.

  In particular, according to the present embodiment, the program setting data S is automatically generated based on the database D2, so that the creation of the setting data S can be made efficient by minimizing human intervention, There is no inconsistency among the development connection diagram D1, the database D2, and the setting data S. That is, since the setting data S of the program that is the final product matches the description content of the development connection diagram D1 as a starting point, the program can be confirmed by checking the development connection diagram D1 in the validity evaluation after the program is generated. Can be easily evaluated, improving the reliability of the entire program.

In addition, this invention is not limited to the said embodiment, The thing illustrated below and other embodiment other than that are included. For example, if the setting data is generated, the configuration and effect of the present invention are satisfied, and the combination with the program may be optional. In addition, one or both of the rationality checks at the time of database creation and setting data creation and the corresponding configuration, and the reflection to the expanded connection diagram after database update and the corresponding configuration can be omitted in the same way. is there.
