Description

DISTRIBUTION LINE SIMPLIFICATION INFORMATION PROVIDING SYSTEM AND SIMPLIFICATION METHOD

The present invention relates to a distribution line simplification information providing apparatus and a distribution line simplification method indicating a geographical arrangement of a distribution line, and in particular, to simplify location information on facilities to confirm a schematic configuration of a power grid. The present invention relates to a distribution line simplification information providing apparatus and a distribution line simplification method.

Electric power facilities are deployed in a wide area, so it is advantageous to express them as maps using geographic information in order to understand the current status. The distribution line can easily perform distribution route or power plant location selection by using map information together. In consideration of these circumstances, power companies manage facility information for stable operation of power facilities, and the location and connection information of each facility is systematically managed through GPS coordinate measurement.

In particular, in order to manage the city's energy information in a smart city environment, the person in charge of city operation must be able to know information about the power distribution facilities installed in the city. However, in the case of power facilities, as it is a national security facility, accurate facility information cannot be leaked to an external system, so there is a need to simplify the information and express it only to the extent that it can confirm the schematic configuration of the power grid.

The conventional distribution line expression method is a schematic method that allows you to easily understand the network structure of the power system regardless of the actual coordinates of the distribution facility based on the substation, or a single-line diagram and distribution line required for distribution operation for stable power supply. For construction and customer service, the facility diagram expressed on the map is used based on the actual coordinates.

In the case of a GIS-based facility diagram, the facilities are accurately expressed on the map, so it is very useful when responding to individual customers and performing line construction.

In the case of city operation manager, there is no need to respond to individual customers and perform line construction, etc., and the main purpose of the smart city energy monitoring system is to understand roughly how power facilities are distributed on the entire city map. It is appropriate to show the simplified distribution line in the form of a method.

As a method for providing power facility drawings according to the prior art, a system capable of generating a single line diagram of a distribution system including connection information and facility information of the distribution system has been proposed. The system includes: a node tracking unit that tracks a distribution line using system information of a geographic information system (GIS) and configures a tree with facilities included in the distribution line as nodes; a node arranging unit that determines the level of nodes using the tree and generates a single-line diagram in which the nodes are arranged according to the level; A rearrangement unit for rearranging the nodes on the single-line diagram using location information of the geographic information system is provided, and the facility is arranged by reflecting the location information of the GIS in a single-line diagram generation method that expresses power facilities with vertical and horizontal components .

As another method, a method of configuring a single-line diagram to facilitate monitoring of the switchgear state and the blackout section has been proposed. We propose a single-line diagram-based distribution system visualization device that expresses the connection relationship of distribution lines in a single-line diagram consisting of nodes and arcs in a central control room at a remote location through the topology analysis section, tree composition section, and tree rearrangement section. Alternatively, by collecting the open state in real time, it includes a display unit that dynamically visualizes the distribution system operator for easy identification and displays it on a single line diagram. This is to increase the identification of the distribution system operator by dynamically displaying the operating status of the switchgear of the distribution line, and to induce prompt recovery in the event of a failure.

As another method, a CIM system diagram processing method that can express distribution system information according to the IEC 61970 standard CIM (Common Information Model) and easily draw a distribution system has been proposed. Here, distribution system information is expressed using Terminal and ConnectivityNode, the grid facility connection structure generator constructs an mRID set of all routes from the start point to all endpoints, creates a HashMap and stores it in the Hash route storage, and the mRID deleter We propose a method of drawing the distribution system while deleting the mRID from the path storage. Abbreviated ID enables fast operation, and in addition to the fast operation speed, the distribution diagram can be stored and drawn with the same accuracy as the existing CIM diagram processing method.

As another method, a method of automatically simplifying data when synthesizing shape data for making a numerical map of a desired scale from a numerical map of the minimum scale was proposed. Specifically, it is a method of simplifying data when synthesizing shape data to create a higher-level numerical map by processing a lower-level numerical map. For arbitrary shape data, when the total number of shape coordinates is three or more, the total number of shape coordinates is two by deleting the midpoint when the distance between the midpoint and the intersection point among the lines orthogonal to the straight line connecting the beginning and the end point exceeds the tolerance. This method is repeated until the following. This method is used to create a multi-level numerical map by processing a numerical map of a specific level, and is intended to minimize the error when creating a large-scale numerical map from a small-scale numerical map.

As another method, the digital map production method includes: a data input module unit for receiving a numerical map produced using numerical map production software from an operator; a generation module unit for selecting a polyline object to generate an MPolygon object; an attribute information setting module unit and an attribute information attachment module unit configured to set values of attribute information; a search extraction module unit that searches for MPolygon existing in a numerical drawing; a change module unit that converts MPolygon into a general polyline; a database module unit for managing MPolygon objects; and a control module for generating multi-polygons. This method simplifies the operation procedure by giving only attribute information to the object without creating a new object, so that polygons and multi-polygons can be created and managed, and the operation procedure is simplified.

As another method, a system for automatically editing a large-scale numerical map into a small-scale numerical map was proposed, which eliminates errors between workers and simultaneously produces a fast and accurate small-scale numerical map. A module to obtain the original numerical map data of the target work area, a module to delete an unused feature layer from the reduced numerical map, a module to create a classification file by categorizing by major categories, and a reduced number of N maps of the original numerical map It consists of a connection module that regenerates the map into one map leaf, a module that organizes features, a module that removes and simplifies deviations between features, and a module that outputs a reduced numerical map by combining the results organized by classification, A large-scale numerical map can be quickly and accurately converted into a small-scale numerical map.

The above-described method for providing drawings of power equipment according to the prior art is a technology for minimizing data processing errors during map conversion and technologies for accurately indicating the location of equipment on a map (GIS), which simplifies location information to maintain security. No workaround is suggested.

1 is a screen showing a general facility diagram of a power distribution facility.

1 is a facility diagram of a distribution facility using an existing numerical map. For distribution facility management, electric power companies use the power facility based on a Geographic Information System (GIS) to express data with PolyLine, Point, and attributes. are doing

The existing facility diagram shown uses GPS coordinates to display power facilities with an error of less than 1 meter, so it is effectively used for power company employees to link with navigation when a customer visits or troubles, or to establish a facility expansion plan. . However, the illustrated facility diagram precisely provides information on national security facilities, and cannot be provided to external organizations other than power companies. In recent years, as the development of green new deal technologies such as smart cities increases, it is difficult to provide public use of the illustrated facility drawings even if the need to provide a level of simplified facility drawings that can be provided to the outside increases.

2 is a screen showing a simplified diagram of a distribution line simplified according to the spirit of the present invention.

An object of the present invention is to provide a general user with a simplified diagram of a distribution line having the precision shown in FIG. 2 .

The illustrated, simplified distribution line drawing divides the line into upper/middle/lower according to importance, and defines the minimum distance for expressing the line in a simplified drawing by importance, and deletes the line whose length is less than the minimum distance, Tracks that are curved according to roads, buildings, and terrain are simplified and displayed with straight lines. Through this display method, information on the density of power facilities or the direction in which power is supplied can be provided by simplifying facility drawing information that may cause a security problem when leaked to the outside.

3 is a block diagram illustrating an embodiment of an apparatus for providing simplified distribution line information according to the spirit of the present invention.

The illustrated distribution line simplified information providing apparatus includes: a data collection unit 100 for collecting map information and facility information on distribution facilities from an external server such as a power company; a line information generating unit 220 for generating a line information table and a line weight table from the map information and facility information on the power distribution facility;

a single line processing unit 240 that simplifies the lines in a manner of converting the lines to a single line based on the minimum length;

a line integration processing unit 260 for merging points to simplify a connection relationship between lines; and

It may include a simplified information output unit 400 for outputting a distribution line drawing according to the simplified information.

The entire system for performing distribution line simplification processing includes a data collection unit 100 that receives facility drawing data managed by a power company, and a line information generation unit that generates a line information table and a line weight table with the received data ( 220), a single line processing unit 240 that deletes or simplifies according to the minimum length for each line in the line information table, a line integrated processing unit 260 that integrates and processes connection information between the lines, and finally completed simplified It can be seen that the simplified information output unit 400 for outputting a drawing is configured.

Depending on the implementation, as shown, the line information generation unit 220, the single line processing unit 240, and the line integrated processing unit 260 are separate and independent devices, and the simplified processing drawing generator 200 may be configured. .

The data collection unit 100 includes PolyLine information for lines necessary to produce a simplified drawing of power facilities and whether high/low pressure, underground/processing, three-phase information, facility specifications, etc. for weight calculation of power facilities. Attribute information is collected from the power system. The collected information may be stored by configuring an initial line information table. The initial line information table is composed of line connection information according to equipment drawing data input from the outside, and the initial line information table may also be stored for a long time in order to recalculate when the weight setting is changed later.

According to an embodiment, the apparatus for providing simplified distribution line information may further include a user input unit 500 that receives, from a user, values that need to be set according to the purpose of use of the simplified drawing.

The user input unit 500 may receive input from the user as values that need to be set according to the purpose of use of the simplified drawing, for example, the minimum line display distance d and the weight for each equipment attribute.

The minimum line display distance d is a minimum length value of a line to be displayed in a simplified drawing. Accordingly, when the length of a single line is less than or equal to the minimum length, it is not indicated in the drawing. Since the expression method on the map may be different depending on the use of the track, it is advantageous that the input minimum distance is applied differently according to the weight for each track. For example, if the weight of the line is upper or intermediate, the minimum length d may be applied, and in the case of lower weight, 2×d may be applied.

The weight for each facility attribute is for calculating the weight of the line using attribute information of the line. A weight value for each property of each line may be input from the user so that the weight of the line can be changed according to the purpose of using the simplified drawing.

As shown, the line information generating unit 220 includes: a weight calculation unit 224 for calculating a weight using the actual configuration information (PolyLine information) for the line, facility information of the line, and a weight for each facility attribute; and a table generating unit 222 for generating and storing the line configuration information (PolyLine information) for the line, the line facility information, the line information table in which the weight for each facility property is recorded, and the line weight table in which the calculated weight is recorded. may include

The database unit 300 may store an initial line information table, a line information table on which simplified processing has been performed, a distance list, a line weight table, and attribute information of a line, and may be input by a user through the user input unit 500 ( Set) the minimum distance (d) for the line display and the weight for each property of the facility may be stored.

4 is a conceptual diagram illustrating a process of converting GIS facility diagram data into a line information table.

Table 1 below shows a line information table and a line weight table.

For example, when there is GIS-based facility diagram data as shown on the left of FIG. 4 , the data collection unit 100 extracts PolyLine L1, L2, and L3 information shown in the drawing and stores it in the illustrated database unit 300, The information generating unit 220 may generate a line information table and a line weight table necessary for generating a simplified drawing in the form below. The weight of the line can be calculated by multiplying the attribute information of the subsection items included in the line connection information of each line by the weight for each attribute and then adding them.

Each of the points (points) P1_1, P1_2, ... in FIG. 4 is a reference point of an individual section of a distribution line in the power company facility drawing, and may be, for example, a location point of a pole.

The line connection information consists of subsections connecting two points, and the weight of each subsection is high/low voltage of the power facility (ie, line) of each subsection, whether underground/processed, three-phase information, It may be assigned according to attribute information such as equipment specifications (capacity). For example, when the corresponding line is high voltage, in the case of underground, in the case of three phases, a high weight may be given, and a weight proportional to the capacity may be given.

As shown in FIG. 3 , the single line processing unit 240 selects a simplified area for the line by using the line center line connecting the start point and the end point of the target line based on the branch and the minimum line mark distance to select the line simplified area calculation unit. (242); and a simplification processing unit 244 that performs a simplification operation by deleting points outside the line simplification area. That is, the single line processing unit 240 performs line simplification for individual lines existing in the line information table.

5 is a conceptual diagram illustrating a line simplification process for the L1 line of FIG. 4 .

For example, in the case of the illustrated L1 line, a center line connecting P1_1 (start point) and P1_11 (end point) is generated, and an area separated by a line simplification distance (d/2) from the line center line is selected as the line simplification area. At this time, basically, the starting point (P1_1) and the ending point (P1_11) of the line and the intersection points (P1_4, P1_10) with other lines are not deleted even if the line simplification work is performed, and points such as P1_2 and P1_3 exist within the line simplification area. will be deleted

6 is a conceptual diagram illustrating a line simplification process for the L2 line of FIG. 4 .

For example, in the case of the illustrated L2 line, when the line weight is lower, the minimum line display distance is 2×d. Since all points of L2 are within the line simplification area, all points are deleted leaving only the start point (P1_4(P2_7))) and the end point (P2_1). If only the starting point and the end point exist, if the length of the center line of the line is smaller than the minimum distance for the line mark, the line itself is deleted because it is not necessary to mark the line in the simplified drawing.

7 is a conceptual diagram illustrating a line simplification process for the L3 line of FIG. 4 .

For example, in the case of the illustrated L3 line, when the line weight is in progress, the minimum line display distance d is used. Since all the points of L3 are within the line simplified area, only the start and end points exist, and the length of the center line of the line is longer than the minimum distance to display the line, so the corresponding line is displayed on the simplified drawing.

Through the line simplification shown in FIGS. 5 and 7 , L2 is deleted, and finally remaining line connection information is as shown in Table 2 below.

8 is a conceptual diagram illustrating a line simplification process for an L4 line.

For example, in the case of the illustrated L4 lines P4_1, P4_2, P4_3, P4_4, and P4_5, the line is out of the line simplified area. P4_2 and P4_3 present are not saved, but P4_4 is saved when P4_4 is out of the line simplification area. At this time, P4_3, which is the previous point of the deviated point, is also saved, and the line simplification area is continued by setting P4_4 as a new starting point. Since P4_5 is in the new line simplification area, it is deleted and finally the line connection information of the L4 line becomes (P4_1, P4_3, P4_4, P4_6).

9 is a flowchart illustrating a distribution line simplification method as a line simplification process of the single line processing unit 240 of FIG. 3 .

A distribution line simplification method according to the illustrated flowchart includes generating a target line list using a line information table (S110); If there is a line that has not been simplified in the target line list (S120), designating it as a work line, generating a center line of the line and setting a line simplification area (S125); If there is a point that has not been simplified in the line connection information of the work line (S130), selecting it and checking whether the selected point is a starting point, an end point, or an intersection point (S160); If the selected point is a start point, an end point, or an intersection point, storing it in the work connection information as processed (S165); If the selected point is not a starting point, an end point, or an intersection point, checking whether the selected point is in the line simplification area (S170), and deleting the selected point if it is in the simplified area (S175); If the selected point is out of the line simplification area, storing the selected point and the previous point on the line in the work connection information (S180); changing the selected point to a starting point, and calculating a line centerline generation and simplification area (S185); If only the start point and the end point exist in the work connection information (line connection information under simplified processing) (S192), and the length of the center line of the line is less than the minimum distance for the line display (S194), the step of deleting the work line from the line information table (S196) ); If there is a point different from the start point and the end point in the work connection information, it may include a step (S198) of changing the line connection information of the work line to the work connection information.

As the line simplification processing process shown in FIGS. 5 and 7 , the single line processing unit 240 of FIG. 3 performs the line simplification process of deleting points belonging to the line simplification area in the line S120, S125, S130, S160, It can be performed according to steps S165, S170 and S175.

As the line simplification process shown in FIG. 6 , the single-line processing unit 240 may perform the line simplification process of deleting a line shorter than the minimum length of the line display according to steps S192, S194, and S196.

As the line simplification process shown in FIG. 8, the single-line processing unit 240 may perform the line simplification process of setting the line simplification area again based on points other than the line simplification area according to step S185.

The illustrated distribution line simplification method is an arrangement of the line simplification processes of FIGS. 5 to 8 performed by the single line processing unit 240 of FIG. 3 according to a sequential flow, and the important tasks performed in the line simplification process are as follows. .

In the illustrated step S110, all line information is extracted from the line information table to generate a line list for work.

In the illustrated step S125, a line in the line list is selected and designated as a work line, the work area information is initialized, the line center line is generated, and the line simplification area is calculated.

In the illustrated steps S160, S165, S170, S175 and S180, for all points appearing in the line connection information of the work line, the starting point, the end point, and the intersection point are stored in the work connection information, and the points in the line simplification area are excluded from the work connection information. and the points beyond the line simplification area are stored together with the previous point in the work connection information.

In the illustrated step S198, when the processing of all points of the work line is completed, the contents of the remaining points in the work connection information are changed (updated) to the line connection information for the corresponding line in the line information table. At this time, when only the start point and the end point remain in the work connection information, and the length of the center line of the line is smaller than the minimum distance displayed on the line, the corresponding line is deleted from the line information table (S196).

As shown in FIG. 3 , the line integration processing unit 260 includes a point-to-point distance calculation unit 262 for calculating a point-to-point distance with respect to points existing in the line information table; and a point merging processing unit 264 that searches for points having a distance of d/2 or less and merges them into one point. That is, the line integration processing unit 260 performs a line simplification operation as a point merging process for points belonging to the line.

10 is a conceptual diagram illustrating a line simplification process of a point merging process for L4 and L5 lines.

In the case of merging two points, if the track weights of the two points are different, it is changed to a point of the line having a higher weight. Here, as the line weight of each point, the highest weight among the weights of the lines to which each point belongs may be applied.

In the case of the illustrated L4 line, since P4_1 and P4_3 exist within a distance of d/2, they are merged into P4_1. On the other hand, in the case of the L5 line, P5_2 and P4_4 are the same point, and since P4_4 has a high line weight, it is changed to P4_4, and P5_3 and P5_4 are merged into P4_4 because they exist within a distance of d/2 from P4_4.

11 is a flowchart illustrating a distribution line simplification method as a simplification process by the point merging process of the line integration processing unit 260 of FIG. 3 .

The distribution line simplification method according to the flowchart shown includes the steps of extracting all the processing target points from the line information table (S210); generating a list of distances by calculating a distance between two points for all points (S220); selecting a distance value that has not been simplified (S225) in the distance list, and checking whether the distance value between two points is smaller than a reference value (2/d) (S230); If the distance value of the two points is in the range of 0, changing the two points to one point (S270); comparing the line weights of the two points when the distance value between the two points is less than the reference value and does not have a range of 0 (S245); If the line weights of the two points are different, changing the line information table from a low line weight point to a high line weight point (S260); and if the weights of the two points are the same, calculating the center points of the two points and changing the two points to the center points in the line information table ( S255 ).

The illustrated distribution line simplification method is a sequential flow of the point merging processing simplification processes of FIG. 10 performed by the line integration processing unit 260 of FIG.

In the illustrated step S210, after extracting all points from the line information table, a distance list is generated by calculating the distance between two points for all points.

In the illustrated steps S225, S230, S240 and S270, if the distance value between two points for the distance value in the distance list is less than d/2, the maximum distance for line integration, the process of integrating the two points into one is repeated. .

In the illustrated step S270, when the distance value between the two points is less than 2/d and the two points have the same position (the distance value of the two points is 0), it is changed to a single point and stored in the line information table.

In the illustrated steps S245, S250, S255 and S260, if the distance value between two points is less than 2/d and the line weights of the two points are the same, the center points of the two points are calculated and both points of the line information table are changed to the center points. and stored, and if the line weights are different, the line information table is changed from a point with a low weight to a point with a high weight.
