DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system for automatically determining a planned power outage section in a power distribution system control system for automatically determining a line section requiring a power outage for the construction of power distribution facilities.

[0002]

2. Description of the Related Art Distribution system control systems are automated by installing switches that can be remotely controlled at various locations on distribution lines and remotely operating these switches from computers installed at distribution branch offices and sales offices. In addition, an automatic accident recovery function is added to this to shorten the power outage time. In recent years, there has been an increasing number of functions to which a function of automating daily power distribution operations other than at the time of an accident is added. FIG. 3 is a configuration diagram showing an example of such a distribution system control system. In the figure, reference numeral 51 denotes a computer, 52 denotes a console, and 53 denotes a distribution system. In each drawing of this specification, ● indicates a switch, one indicates a track, □ indicates a CB, a hatched area indicates a power outage range, uppercase letters indicate section names, lowercase letters indicate track names,
A dotted arrow indicates a data reference path. Now, in the system shown in FIG. 3, when construction such as new installation, change, or removal of distribution equipment is planned, the operator registers the construction subject 54 in advance in the system (computer 51). The registered contents are the construction date and the construction contents, and the construction contents are the target equipment and the construction type. The target facility is, for example, a “switch”, and the construction type is, for example, “new”. Next, corresponding to the registered construction subject 54, the on-site work and switch operation required for the construction are registered in the system as the work subject 55. The contents of the work subject 55 include the start / end date and time of the switching / work / return operation, the operation procedure, the section of the power line, and the like. The power line section is a range of a line where power is stopped for the safety of on-site work, and is input by an operator by judging from the position of the facility to be constructed on the distribution line. It is, for example, C
The operation is performed by displaying a distribution line diagram on the RT and picking the section with a stylus pen. Note that a section is a set of distribution lines divided by switches. The construction subject and the work subject registered in advance in this way are called up on the CRT screen of the console 52 and executed on the day of the implementation. Construction subject 5
In the case of 4, when execution is instructed, the contents of the construction subject are reflected in the distribution system data 56 managed by the system. For example, in the case of a new construction of a switch, the distribution system data 56 is updated as if the switch was newly installed on the track. Further, in the case of the work subject 55, when execution of each operation of switching, work, and return is instructed, the switch remote monitoring control means 57 remotely controls the switch or updates the system status according to the operation procedure. I do. At the time of work, the power outage will actually occur as the power outage section is set in advance.

[0003]

By the way, in the conventional power distribution system control system, when registering a construction subject, the contents of the construction indicating what kind of construction is to be performed on which distribution line is input. Then, when registering a work subject corresponding to the construction subject, a track section requiring a power outage for construction is input. The "track section requiring a power outage for construction" is the minimum necessary range of a line that causes a power outage for safe work, and since the power outage is performed by operating a switch, the section is a unit. In other words, a new switch is designated in the construction subject as shown in FIG. 4A, and a stop line section is designated in the work subject as shown in FIG. 4B. This means that the same information must be entered again in the work subject, despite the fact that the work location was entered in the work subject.
It is displayed on T, and in addition to instructing the section of the power line section using a stylus pen or the like, various related menu items must be instructed, which is a rather complicated operation. In addition, the same information is input twice for the construction subject and the work subject. However, there is a high possibility that the two will be inconsistent when the operators are different due to work assignment. If the subject is implemented without discrepancy, the construction site will be in danger without a power outage, or a site unrelated to the construction will be harmed by a power outage. SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and provides a construction power outage scheduled section automatic determination method for saving labor and speeding up input, preventing input errors, and preventing danger and damage. It is an object.

[0004]

Means for solving the above-mentioned problems in the present invention are: a construction title representing the construction date and time, and the contents of the construction of the new installation or change of the construction object equipment including the switch; In the system for automatically determining the scheduled power outage section of the distribution system control system in which the start / end dates and times of the switching / returning operation and the work subject including the device operation are registered in advance, the work date and time and the line name as the work location are used. A work subject data file for storing data items including the work subject, a work subject data file having a work subject corresponding to the work subject, and having a work subject keyword corresponding to the work subject entered at the time of the work subject registration; and A section comprising a set of lines divided by a switch and a line section data file for storing a relation between the line and the section to which the line belongs are provided. The construction subject line is retrieved by referring to the construction subject data file from the construction subject keyword input at the time of the work subject registration, and the section to which the line belongs is retrieved by searching the line section data file using the relevant line as a key. A construction power outage scheduled section automatic determination method is characterized in that it is determined as a power outage section.

[0005]

According to the present invention, there is provided a system for automatically determining a scheduled power outage section in which the input is saved by improving the data configuration of the distribution system control system. The present invention includes a construction subject data file, a work subject data file, and a track section data file, the construction subject data saves a track of a construction location, the work subject data saves a keyword that refers to a corresponding construction subject, The track section data is searched for the section to which the track belongs by using the track as a key. Therefore, if the construction subject keyword is input when registering the work subject, the construction subject is referred to by the keyword at a desired timing thereafter, and the track section data file is searched by using the extracted construction track as a key and found. It can be determined that the assigned section is a stop line section.

[0006]

Embodiments of the present invention will be described below in detail with reference to the drawings. FIG. 1 is a configuration diagram showing one embodiment of the present invention. In the figure, 1 is a construction subject data file,
2 is a work subject data file, 3 is a track section data file, and 4 and 5 are distribution systems. Construction subject data
Similar to the conventional example, each construction subject is represented, and includes data items such as construction date and time and a track name as a construction location. The work subject data also represents the work subject corresponding to each construction subject, as in the conventional example. In the present invention, however, the work subject data further includes a keyword capable of referring to the construction subject corresponding to the subject. This is, for example, a serial number given to each construction subject, a so-called subject No. Or a unique name or construction number for each construction. It may be. If these are not included in the data, they will be set again. The track section data indicates the relationship between tracks and sections, and indicates to which section the track belongs, indicates a set of tracks that make up the section, and can be referenced using the track or section as a key. And

FIG. 2 is a process chart showing an example of the processing of the above embodiment. In the figure, the operator first (1)
After the registration of the construction subject data 1, (2) the work subject data 2 is registered, and at that time, the keyword of the construction subject is also input. Next, (3) the construction line is taken out by referring to the construction subject data 1 corresponding to this keyword. Further, (4) the line section data 3 is searched using the line as a key, and the section to which the line belongs is taken out. (5) This section is automatically determined as a power line section. Thereafter, the switch operation procedure is automatically created based on the determination result, or the support information is displayed on the CRT in the case of manual creation. Note that (1) and (2) of the processing shown in FIG. 2 are interactive processing by the operator, and (3) to (5) are automatic processing of the computer.

This embodiment has the following advantages.

(1) In the conventional method, the input operation is complicated because the power failure section is input one by one. However, in the present invention, the input of the power failure section becomes unnecessary, and the operation is greatly simplified, and the business operation is simplified. Labor saving and speeding up become possible.

(2) In the conventional method, since it is necessary to input the construction site and the corresponding power outage section, there is a possibility that the two may be inconsistent due to an input error caused by carelessness or erroneous recognition. In the present invention, input of information is unified by simply inputting a construction location, input errors can be completely prevented, and there is no inconsistency.

(3) Due to the above (2), work is not performed while the construction location and the power outage section do not match,
Prevents the danger that power is lost at places where power is to be cut off and that is irrelevant to construction work, which could cause a great deal of damage to life, economy and society due to power cuts.
