Abstract

PURPOSE:To realize automatic decision of service interrupting work section in a control system for distribution system where the name of work, detailed name of work, etc., are processing objects, and to save manpower and prevent input miss of information by eliminating input of service interrupting work section including service interrupting section. CONSTITUTION:Work name data, detailed work name data, line section data, work section group data, and section switch connecting data are provided. When a detailed work name is registered, one or more work name keyword is inputted and then the work name keyword is taken out one by one in order to decide a service interrupting line section with reference to each data. Service interrupting line sections associated with work dates are temporarily stored as a work section group data and after all work name keywords are processed, the service interrupting work section is taken out one by one from the work section group data. A service interrupting work section is then decided by retrieving the section switch connecting data and referring to the work section group data. The processing is carried out for all work service interrupting sections.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique for automatically dividing a line section requiring a power outage for construction of power distribution equipment in a power distribution system control system so that a power outage time is short and work efficiency is good. It relates to an automatic determination method.

[0002]

2. Description of the Related Art A distribution system control system is a system that installs switches that can be remotely controlled at various points on a distribution line and automates switch operations by remotely controlling from a computer installed at a distribution branch or sales office. .. Based on this, an automatic accident recovery function is added to reduce the power outage time.

Further, in recent distribution system control systems, as shown in FIG. 4, more and more systems are added with a function for automating a normal distribution operation work except when an accident occurs. In FIG. 4, first, when construction work such as new installation, change, and removal of power distribution equipment is planned, an operator registers in advance in the system as a construction subject. The content of the subject to be registered is the construction date and time and the construction content. The details of the construction are the target equipment and the type of construction. For example, the target equipment is "switch" and the construction type is "new"
And so on.

Next, in accordance with the registered construction subject, on-site work and switch operation required for construction are registered in advance in the system as work subjects. The content of the subject is switched,
Work, start of revertive operation, end date and time, operation procedure, power outage section, etc. This power outage line section is the range of the line that will be out of power for the safety of on-site work, and the operator judges and inputs it from the position on the distribution line of the target equipment. That is, for example, an operation of displaying a distribution line diagram on a CRT and picking the section with a stylus pen. The section is a set of distribution lines divided by switches.

The construction subject and the work subject thus registered in advance are called on the CRT screen on the day of the implementation. In the case of the construction subject, when the execution is instructed, the contents of the construction subject are reflected in the data of the distribution equipment managed by the system. For example, if the switch is newly installed, the facility data is updated so that the switch is newly installed on the track.

In the case of a work subject, switching, work,
When the execution of each operation for switching back is instructed, the switch is remotely controlled and the system state is updated according to the operation procedure. During the work, the power outage line section will actually fail as set in advance.

Here, the construction subject and the work subject are registered, as shown in FIGS. 5 (a) and 5 (b), separately by inputting the construction portion and the power failure portion due to the construction, respectively. The input operation is quite complicated. In addition, even though the information is similar, since the information is input separately, input errors are likely to occur, and the contents are likely to be inconsistent. Furthermore, if the construction subject and the work subject are carried out while the construction site and the power failure site do not match, a dangerous situation will occur in which the construction site will not suffer a power failure.

In order to solve this problem, there has been conventionally proposed the "automatic determination of construction blackout scheduled section". This system first has a data structure as shown in FIG. That is,
Construction subject data that holds the track name of the construction site, and work subject data that holds the keyword of the corresponding construction subject,
It has track section data that can be used to extract the section to which the track name belongs by using the track name as a key. Then, based on the data structure, a processing method as shown in FIG. 7 is adopted. That is, after the construction subject name is registered, when the corresponding work subject is registered, the keyword of the construction subject is also entered. After this input, the line name of the construction site is extracted by referring to the construction subject corresponding to the keyword. Further, with reference to the track section data with the track name as a key, the section to which the track belongs is extracted. This section is automatically determined as the scheduled power outage section.

[0009]

[Problems to be Solved by the Invention] In one work subject,
In consideration of work efficiency and shortening of power outage time, there are many cases where multiple construction subjects whose time is close to the place are targeted. In this case, there may be multiple scheduled power outage sections.

Even if there are a plurality of construction blackout scheduled sections, the section group does not have a simultaneous blackout in the implementation work. In consideration of the work efficiency and shortening of power outage time in more detail, the sections where the construction time is close to the place are set as one group, and the power outage is implemented for each group. This group will be referred to as a power failure construction zone hereinafter.

Conventionally, when registering a work title, an operator inputs a scheduled power outage section for each power outage section and specifies a power outage time to classify the power outage section.

The above-mentioned "automatic determination system for scheduled power outages"
Then, the planned power outage section is automatically determined, but the blackout section is not classified. In order to compensate for this, the operator must perform a complicated input operation that divides the planned power outage sections into power outage sections. If this happens, input and judgment errors may occur, and the construction time and power outage time may not match. If the construction time and the power outage time do not match, it will be dangerous because the work will be performed without power failure.

The present invention has been made in view of the above points, and an object thereof is to enable automatic determination of a power outage section and to eliminate the need for inputting a power outage section including a power outage section to save labor in operation work. It is to provide an automatic judgment method of a power failure site that prevents information input errors.

[0014]

[Means for Solving the Problems] In the present invention, in a distribution system control system for processing a construction subject or a work subject, reference is made to the construction subject data for storing the track of the construction site and the construction date and time, and the target construction subject. Work subject data that saves multiple possible keywords, track section data that allows you to retrieve the belonging section using the track as a key, construction section group data that temporarily saves the construction date and time with the construction date and time, section and switch With the section switch connection data that allows you to search for adjacent sections using the key, enter one or more construction subject keywords when registering the work subject, then retrieve the construction subject keywords one by one, and use the key Refer to the subject to retrieve the track of the construction site and the construction date and time, use the track as a key to refer to the track section data, retrieve the section to which it belongs, and cut the section to blackout. After performing the first judgment process for all construction subject keywords, which is determined as a road section and temporarily stores the construction date and time as construction section group data, one construction blackout section from the construction section group data Take out the section, search for section switch connection data using the section as a key, extract the adjacent section, extract the construction date and time of the section and the adjacent section from the construction section group data, and if both construction dates are close, It is characterized in that the second determination process for recognizing the same power outage section is performed for all the construction power outage sections.

[0015]

[Operation] The construction subject keyword registered in the work subject data is taken out one by one, the first judgment processing is performed for all the construction subject keywords, the power failure line section is judged, and the construction date and time are attached to the construction section group data. As a temporary save. Next, if the construction blackout sections are taken out one by one and the second judgment processing is performed for all the construction blackout sections, the construction blackout sections are divided for each blackout section.

As a result, it is not necessary to input the power outage section and the power outage construction zone by only once inputting the construction site and the construction date and time, and the input of the same information is unified. Therefore, there is no possibility that the construction site, construction date and time, blackout section, and blackout section will not match, and input errors can be completely prevented.

[0017]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. In order to solve the above-mentioned problem, first, the data structure shown in FIG. 1 is adopted as in the case of the conventional “automatic determination system for scheduled power outage section”. The construction subject data is the same as before, and there are data items such as the construction date and time and the track name as the construction site.

The work subject name data is also the same as the conventional one, but it is assumed that it has a plurality of keywords that can refer to the construction subject name corresponding to the subject name. For example, a serial number assigned to each construction subject, so-called subject number. Or a unique name or construction number for each construction subject. And so on. This may be held for screen display even in the past, but if not, it is newly provided.

Further, there is line section data that represents a set relationship between a line and a section. This represents to which section the track belongs, or represents a set of tracks that make up the section. In addition to the above, the data structure of FIG. 2 is adopted in the present invention in which each line and section can be referred to as a key. First, there is construction section group data as data for temporarily storing the construction blackout section. This is to list up the section group of the work subject to the power outage with the work date and time attached.

Further, there is section switch connection data that represents the connection relationship between sections and switches. This represents a switch connected to a section, or searches for an adjacent section via a switch connected to the section. Each section and switch can be used as a key for reference and search.

Based on the above data structure, the processing shown in FIG. 3 is performed. First, after registering the construction subject, the operator registers the work subject, and at that time, the operator should also input the keyword of the construction subject. After this input, the construction subject keywords are extracted one by one and the construction blackout section is determined. As for the detailed processing, as shown in FIG. 1, the corresponding construction subject data is referred to by the construction subject keyword as shown in (1) in FIG. Further, as in (2) in the figure, the line is used as a search key to refer to the line section data, and the section to which the line belongs is extracted. Then, this section is determined as a construction power failure section as shown in (3) in the figure.
At this time, as shown in (4) in the figure, the construction date and time is also attached and saved in the construction section group data.

When all the construction subject keywords have been processed, the construction blackout sections are taken out one by one,
Determine the power outage area to which it belongs. The detailed process is, as shown in FIG. 2, first, referring to the section switch connection data using the section as a key as shown in (1) in the figure, the switch to be connected is acquired. Further, as in (2) in the figure, the section switch connection data is searched using the switch as a key, and a section adjacent to the section is acquired via the switch. Next, using the acquired adjacent section as a key, refer to the construction section group data as shown in (3) in the figure, compare the construction dates and times of the adjacent section and the section as shown in (4) in the figure, and find that they are close to each other. If in the figure (5)
Recognize as the same blackout area as shown in. When the above process is completed for all construction blackout sections, they will be divided into blackout sections. After that, planning and executing work interruption for each power outage area is the same as the current one.

[0023]

As described above, according to the present invention, at the time of registering a work subject, after inputting one or more construction subject keywords,
The construction subject keywords are extracted one by one, the construction subject line is extracted by referring to the construction subject with the relevant key, the belonging section is extracted by referring to the section data with the relevant track as a key, and the relevant section is extracted. After performing the first judgment process for all the construction subject keywords, which is judged as a power failure line section and is temporarily saved as construction section group data with the relevant construction date and time attached, one construction blackout section from the construction section group data Each time, the section switch connection data is searched by using the relevant section as a key, the adjacent section is extracted, and the construction date and time of the relevant section and the adjacent section are extracted from the construction section group data. Since the second determination process for recognizing the same as the same power outage section is performed for all the construction power outage sections, the following excellent effects can be obtained.

(1) Labor saving and speeding up of input Under the present circumstances, the input operation is complicated because each blackout section is input one by one. In addition, with the conventional "Construction blackout scheduled section automatic judgment method", it is not necessary to input the blackout section, but it is not possible to determine the blackout section, and input operation to identify the blackout section is necessary, so it is not complicated. It was not resolved. According to the present invention, there is no need to input a power failure section including a power failure section, and the operation is significantly simplified. This makes it possible to save labor and speed up work.

(2) Input and Prevention of Judgment Mistake Currently, it is necessary to input the construction site, the construction date and time, and the power failure section and the power failure section corresponding to each, so there is a case where they do not match. The direct cause is input or judgment error due to carelessness or recognition error, but the input of information that is essentially the same is not unified. That is, inputting the same information twice separately is the true cause of the mistake.

[Conventional "Construction blackout scheduled section automatic determination method"
Then, the blackout section was automatically determined, but the blackout section could not be identified, and input was required to identify the blackout section. As a result, it was possible that there were mistakes in input due to carelessness and erroneous judgments when dividing the power failure section into blackout sections.
The essential cause is the same as above.

According to the present invention, it is unnecessary to input the power failure section and the power failure work zone by only once inputting the construction site and the construction date and time, and the input of the same information is unified. As a result, there is no possibility that the construction site, construction date and time, blackout section, and blackout section will be inconsistent, and input errors can be completely prevented.

(3) Prevention of danger and control of damage In connection with item (2) above, if work is performed with the construction site, construction date and time, the power outage section, and the power outage section inconsistent, power will be applied to the location where the power outage should occur. It is very dangerous. In addition, if there is a power outage in a place unrelated to the construction, or if the power is cut off when it is not the construction date and time, it will cause great damage to the economy and society. The present invention can eliminate this risk and prevent damage.
