Description

[Detailed Description of the Invention] A. Field of Industrial Application The present invention relates to a rule maintenance method of a confirmation item procedure in a power system equipment operation procedure, and more particularly to an AI (Artifici
al Intelligence: A maintenance method for rules that generate confirmation items in a substation automatic procedure creation system that uses an artificial intelligence method.

B. Summary of the Invention The present invention is a rule maintenance method for generating confirmation items by an automatic substation operation procedure creation system using an AI-like method. A condition-related part that contains any of the terms and equipment operating methods, and an execution part that contains the confirmation of the status before and after the operation, the content to be confirmed, and the insertion location as an element. Confirmation procedure that is the most frequently used maintenance item by creating, changing or adding a rule that includes equipment power supply load category, contents of confirmation items and insertion location, and creates syntaxes that assign identification numbers to equipment and facilities. It is possible to enter rules with the minimum number of elements, and the terms should be in accordance with the Japanese description used by substation staff at all times, so that the user side can easily and easily familiarize themselves. Technology that can be used.

C. Conventional technology Conventionally, "device operating procedures" such as switches have been set in power systems such as substations. The contents are categorized into three types: a main circuit (switch) procedure, an accessory equipment procedure, and a confirmation item procedure, and changes and additions are made as necessary, so it is necessary to set rules for that. FIG. 10 is a flow showing an example of the “stepwise inference”, which is composed of a main circuit inference 101, an auxiliary equipment inference 102, and a confirmation item inference 103, and each inference is performed based on a rule.

By the way, those rules are also changed or added as required, and maintenance is required.However, conventionally, the addition of confirmation items at substations was done after the switch operating procedure for each individual purpose command was created. It was determined by electrical reasoning and customs, and was individually added to all individual purpose commands as shown in FIGS. 11 (a), (b) and (c).

D. Problem to be Solved by the Invention However, the rule maintenance method in the conventional automatic creation system of “device operation procedure” has not been performed in Japanese, which is easy for the user to understand. In addition, as described above, it is necessary to perform maintenance for each device individually for each purpose command, and the confirmation items before and after the device operation performed by the staff at the substation site are determined by electrical theory and practice for each device. The rule system was not in place. Therefore, it is unclear what combination of conditions will uniquely determine the "confirmation procedure", and the maintenance frequency will differ greatly between the "main circuit procedure" rule and the "confirmation procedure" rule. Nevertheless, the maintenance was done in exactly the same way. Moreover, conventional maintenance is based on the system side by a computer, and it is very difficult for the user side to have a deep understanding of the data structure of the system.

The present invention was devised in view of such problems, and enables the input of confirmation item procedure rules, which are the most frequently used maintenance items, with the minimum number of elements, and that term is also used by substation personnel at all times. It is intended to provide a maintenance method of the confirmation item rule of the power system equipment operation procedure that can be easily and easily familiarized by the user side.

E. Means for Solving the Problem The means for solving the above problem in the present invention is a confirmation item procedure rule in the rule maintenance method of the power system equipment operation procedure including a main circuit procedure, an auxiliary equipment procedure, and a confirmation item procedure. Includes any of the following: a condition part that contains any of the following: device operation, device type, command facility, command term, and facility operation method, content to check the status before and after operation, and specification of insertion location. A confirmation item that is composed of an execution unit and that creates, modifies, or adds a rule with a syntax that assigns an identification number to the device and facility, including the device, equipment, power load category related to confirmation, the content of the confirmation item, and the insertion location. It is based on the rule maintenance method of the procedure.

F. Action The present invention uses an inductive method from an interview with a substation operator or an actual use procedure, triggered by the recent automatic creation of a device operation procedure of an electric power system by an AI method. Common rules are extracted and they are put together in the condition part and execution part elements of the production rules (if ~, then ~).

The present invention is to maintain the confirmation item procedure rule used for the last "confirmation item inference" among the various rules used for the "stepwise inference". In the automatic creation system, the "main circuit procedure" is used as a key procedure, and a production rule in which "confirmation procedure" is inserted before and after it is created. Therefore, as the element of the condition part of the rule, the "main circuit procedure", that is, "device operation" is the first condition element, and even if the same "device operation" is used, the "confirmation procedure" may depend on the target command. Since it is different, “command equipment” is the second condition element, and even if it is the same “equipment operation” and the same “command equipment”, the “confirmation item procedure” differs depending on the command term, so the “command term” is This is the third condition element. For the case of the service line, the "operation method of equipment" is set as the fourth condition element. On the other hand, the rule execution unit is provided with two execution elements for inserting before and after the key procedure based on the investigation result.

The syntax that should be entered in these condition elements and execution elements is Japanese syntax, including the equipment, equipment, power supply load category related to confirmation, the contents of confirmation items and the insertion place, and the identification number is given to the equipment and equipment. To be done. By associating the identification number with each of the above-mentioned elements, rules can be created, changed, and added in Japanese syntax.

G. Example Hereinafter, an example of the present invention will be described in detail with reference to the drawings.

FIG. 1 is a sample diagram showing one embodiment of the system of the confirmation item procedure rule of the present invention. In the figure, the power system is a substation, the equipment is a switch, and the confirmation item procedure rule is composed of a condition part and an execution part. Elements of the condition part are command terms,
It includes switch operation, command equipment, and operation method of equipment. The elements of the execution part are confirmation of the pre-operation state and confirmation of the post-operation state. As the command term, 4 words of "stop", "use", "use together", "remove use" are set, and the switch is
Various types of service line CB, bus LS, bus CB, bank primary CB, section CB are listed and operated to open or insert.
These switch operations that are combined are the first condition element, and since the "confirmation procedure" differs depending on the target command, a command equipment column is provided as the second condition element, for example, drop line and drop line CB. Distinguished. Also, even if the same switch operation "open the service line CB" and the same command equipment "service line", the "confirmation procedure" differs depending on whether the command term is "stop" or "unlock the combined use". , "Command term" is the third condition element. In addition, as the fourth condition element,
Although it is specific to the service line, the "operation method of equipment" was set to distinguish the power line from the load line. The execution unit is provided with two execution elements for inserting before and after the “key procedure” according to the investigation result.

FIG. 2 is a sample diagram showing an example of the window image of the above embodiment. In the figure, the first row is the rule name,
The first row shows the document contents, the second row to the second row show the condition elements, and the second row to the third row show the execution elements. The left side of each condition element column and execution element column is an instruction to the operator, and the operator shows the blank (A,
All you have to do is fill in B, C, D,).

FIG. 3 is a sample diagram showing an example of Japanese syntax that should be included in each of the above elements. The first syntax 31 in the figure is used in the second stage shown in FIG. Third stage, third syntax
33 is the third stage, fourth syntax 34 is the third stage, fifth syntax 35
Is used in the third stage. In the syntax, those written as i, j, k ... select the above-mentioned A, B, C ... as an identification number, and command equipment, switch, procedure, etc. having the same identification number. Simplifies the construction of the syntax by defining that they are identical in their rules.

On the other hand, A with "attach" and "remove" as command terms
The grounding procedure is summarized in the elements shown in Fig. 4,
Each element 11, 12, 13 and 14 of the window image shown
Insert the Japanese syntax 61, 62, 63, 64 shown in FIG. Correspondence between the identification numbers i, j, k ... And A, B, C.

Summarizing the above into two windows for each command term,
When the command terms are "stop", "use", "combination", "use together" and "unlock combination", by unifying 3 items in the condition section and 4th in the execution section as shown in FIG. In addition, when the command terms are "attach" and "remove", most of the rules can be maintained by unifying the condition section with 10 items in the second execution section as shown in FIG.

An example of changing the confirmation item procedure rule due to the above maintenance is shown below.

(1) First, create a procedure with the rules before the change.

For example, suppose the following procedure is created.

(Objective command = 500KV instep 1 bus stop work) O100 Open R100 Open S100 Open 500KV instep 1 bus 43-99A1 Lock 010 Open 110 Open 210 Open (2) Here, before and after opening 010 in the above procedure,
If it is desired to check the voltage, a rule maintenance request is issued to change the checklist to add a checkpoint procedure rule.

(3) The rule shown in FIG. 9 is added. The figure (a) is a window image, the figure (b) is a syntax list, and the figure (c).
Shows a word list, and FIG. (D) shows a list of identification symbols. Input of the condition request and the execution element is performed as follows by selecting these syntaxes and words.

A syntax list for selecting "operation procedure" is output.

Select the desired syntax in the syntax list.

In the syntax? When a word to which is added is selected, a list of words that can be assigned to the word is output, and a desired word is selected from the list.

Select i, j, k ... in the syntax and enter the identification symbol.

(4) When "Rule expansion" is instructed, the rules entered in Japanese syntax and words are translated into a predetermined computer language.

(5) Try to create a procedure with the changed rules. For example,
The following procedure is created.

(Purpose command = 500KV instep 1 busbar work stop) O100 Open R100 Open S100 Open 500KV instep 1 busbar 43-99A1 Lock * 010 current confirmation 110 Open * 500KV instep 1 busbar voltage confirmation 110 Open 210 Open here * The marked part is the confirmation item procedure output by the added rule.

By applying this embodiment, it is possible to change the following all procedure creation rules.

 As described above, the following effects are apparent in this embodiment.

(1) The user can easily perform maintenance of the “confirmation item rule” that is frequently changed in each substation and is frequently used in operation, which is frequently maintained.

(2) The decision logic of the conditional part is a decision logic that does not make the operator feel uncomfortable by using the terms that follow the Japanese description that the operator of the substation always uses.

H. Effect of the Invention As described above, according to the present invention, the "confirmation item procedure rule" that is most frequently used as a maintenance item.
It is possible to easily perform on the user side by inputting the minimum number of condition part / execution part elements, and the terms of the condition part / execution part should be in accordance with the Japanese description that substation staff always use. It is possible to provide the rule maintenance method of the confirmation item procedure in the operation procedure of the power system equipment, which is easy to be familiar with by the decision logic which does not cause the operator to feel uncomfortable.
