1 is a block diagram of an apparatus for generating a single line diagram of a distribution system according to an embodiment of the present invention. Referring to FIG. 1, the distribution system single-line diagram generation apparatus 10 according to an embodiment of the present invention includes a database 11, an entity generation unit 12, a first processing unit 13, a second processing unit 14, and a second processing unit 14. It may be configured to include a three processing unit 15 and a display unit 16.

The database 11 is a flash memory type, a hard disk type, a multimedia card micro type, a card type memory (for example, SD or XD memory, etc.). ), magnetic memory, magnetic disk, optical disk, RAM (Random Access Memory: RAM), SRAM (Static Random Access Memory), ROM (Read-Only Memory: ROM), EEPROM (Electrically Erasable Programmable Read-Only Memory), PROM ( Programmable Read-Only Memory) may include at least one storage medium. In addition, the database 11 may operate a web storage that performs a storage function or may operate in connection with the web storage.

The database 11 may store a system diagram including connection relationship information of a distribution system facility. The database 11 may receive and store a system diagram from a distribution system operation system (not shown), and may be updated periodically.

In addition, the database 11 may store data and programs necessary for the distribution system single line diagram generating apparatus 10 to operate.

In addition, the database 11 may store various user interfaces (UI) or graphical user interfaces (GUI).

The entity generator 12 may generate an entity including a facility symbol and a concentric circle surrounding the facility symbol for each facility of the power distribution facility. In the embodiment, the power distribution facility may mean facilities such as all transformers, disconnectors, switchgears, switches, circuit breakers, and auto load transfer switches (ALTS) constituting the distribution system. In addition, in the embodiment, the multi-circuit facility may mean a facility in which a plurality of facilities are connected to one switch, a circuit breaker, a switch, and the like.

The entity generator 12 may generate an entity including a concentric circle surrounding the facility symbol after generating facility symbols for all facilities existing in the system diagram. The facility symbol can be represented by a circle. The facility symbol or number corresponding to the system diagram may be displayed inside the circle of each facility symbol.

The concentric circle has a larger diameter than the facility symbol and can be expressed as a concentric circle having the same center point. That is, each individual can be expressed in the form of a double circle having the same central point.

In the case of an n-circuit distribution facility, the entity generator 12 may generate a concentric circle size of a distribution facility connected to a lower end of the n-circuit distribution facility smaller than the concentric circle size of an entity representing the n-1 circuit distribution facility ( n is a natural number greater than or equal to 5). In this case, the entity generation unit 12 may generate a diameter of a concentric circle of the distribution facility connected to the lower end of the n-circuit distribution facility 20% smaller than the diameter of the concentric circle of the entity representing the n-1 circuit distribution facility. In the embodiment, the lower stage may mean a facility located at the receiving end with the facility as the center.

That is, the entity generator 12 generates the same size of concentric circles in case of 1 to 4 circuit distribution facilities, and in the case of multi-circuit distribution facilities of 5 or more circuits, adjusts the size of concentric circles of facilities connected to the lower end of the circuit. Can be generated. In this case, if the diameter of the concentric circle of the 1 to 4 circuit power distribution facility is referred to as the reference diameter, the diameter of the concentric circle of the power distribution facility connected to the lower end of the 5 circuit power distribution facility may be generated 20% smaller than the reference diameter. In addition, the entity generation unit 12 may generate a concentric circle diameter of a distribution facility connected to a lower end of the distribution facility in 6 circuits, 40% smaller than a reference diameter.

Therefore, when the reference diameter is set to 10 cm, the concentric circle diameter of the distribution facility connected to the lower end of the five-circuit distribution facility may be set to 8 cm, and the concentric circle diameter of the distribution facility connected to the lower end of the six-circuit distribution facility may be set to 6 cm.

The reason for reducing the size of concentric circles in this way is that the number and size of concentric circles circumscribed to one concentric circle are limited. Accordingly, the object generation unit 12 may variously determine the reduction ratio of the diameter according to the size and number of circles circumscribed to the concentric circles having the reference diameter.

The first processing unit 13 arranges the objects on the first layer, but in the case of a facility connected to each other, the first processing unit 13 may be arranged so that the concentric circles of each object circumscribe. In an embodiment, the first layer may mean a two-dimensional plane. The first processing unit 13 may sequentially arrange objects according to a connection relationship between facilities using a system diagram. The first processing unit 13 may be arranged such that concentric circles are circumscribed in the case of the entities connected to each other. Accordingly, facility symbols and concentric circles may be expressed in the first layer.

The second processing unit 14 may output the second layer by connecting the facility symbols on the first layer according to the connection relationship between the facilities. In an embodiment, the second layer may mean a two-dimensional plane. The second processing unit 14 may output the second layer by connecting facility symbols of interconnected facilities in a straight line with reference to the system diagram. Accordingly, in the second layer, a facility symbol, a concentric circle, and a straight line connecting the facility symbol may be expressed.

The third processing unit 15 may output a third layer by removing concentric circles surrounding the facility symbols on the second layer. In an embodiment, the third layer may mean a two-dimensional plane. The third processing unit may output a third layer in which only a straight line connecting the facility symbol and the facility symbol is expressed by removing the concentric circles on the second layer. The third layer may be expressed in an unstructured form according to the Cartesian coordinate system of the connection relationship of each facility symbol. That is, in the case of a single line diagram of the existing distribution system, facilities may be disposed in all directions, rather than the method in which facilities were disposed only in four directions, up, down, left, and right based on one facility.

The display unit 16 may display a third layer output from the third processing unit.

The display unit 16 includes a liquid crystal display (LCD), a thin film transistor liquid crystal display (TFT LCD), an organic light-emitting diode (OLED), and a flexible display. ), a 3D display, and an e-ink display.

In addition, the display unit 16 may output various user interfaces or graphic user interfaces on the screen.

2 to 7 are views for explaining the operation of the distribution system single line diagram generating apparatus according to an embodiment of the present invention.

2 shows an example of a single line diagram stored in a database. In Fig. 2, each circle represents a facility, and a number inside the facility represents a symbol for classifying the facility. In general, the facility symbol 1 indicates the power side, and numbers are sequentially assigned according to the connection relationship. The straight line between the installations represents the connection relationship between the installations. According to the number n of facilities connected to one facility, it may be referred to as an n-circuit distribution facility.

Referring to FIG. 3, the entity generating unit may create an entity 20 representing each facility. The entity generator may generate an entity 20 for each facility, including a facility symbol 21 and a concentric circle 22 surrounding the facility symbol 21. In the embodiment, the diameter of the facility symbol 21 is 2 cm, and the diameter of the concentric circles 22 is 10 cm. Here, the diameter of the concentric circles 22 may be set as the reference diameter.

4 to 5, the first processing unit may arrange each entity 20 on the first layer 31 according to a connection relationship between facilities. The first processing unit may arrange each entity 20 on the first layer 31 so that the concentric circles 22 of the entities 20 representing the connected facilities on the system diagram are circumscribed. The first processing unit may sequentially arrange each entity 20 on the first layer from the first facility to the 21st facility. At this time, since the 4th facility is a 5 circuit distribution facility, the concentric circle diameter of the 8th to 11th facilities connected to the 4th facility may be set to 8cm, which is 20% smaller than the reference diameter.

Referring to FIG. 6, the second processing unit may output the second layer 32 by adding a straight line connecting the facility symbols 21 of each facility connected on the system diagram to the first layer.

Referring to FIG. 7, the third processing unit may output the third layer 33 by removing concentric circles of all objects on the second layer. In this case, data indicating the location of the concentric circles on the second layer may be separately stored in the database.

In the single line diagram of the distribution system generated according to the embodiment of the present invention, the restriction of expression for the multi-circuit facility disappears. As a result, the expression of the branch point disappears and the expression of the distribution system can be simplified. In addition, it is possible to continuously connect and express multi-circuit facilities regardless of the number of circuits in the facility.

Also, the expression from left to right disappears in the existing single line diagram. In the existing single-line diagram, the left side is assumed to be a substation, and the switches (switches) connected from the substation are displayed in order. This display method may have been an advantage in terms of current flow in the past distribution lines (floor structure) where distributed power was not connected, but is not suitable because it is a situation in which distributed power is connected to the distribution line and reverse current occurs. .

In addition, since it does not follow the formal arrangement according to the Cartesian coordinate system, the loop display of the distribution line becomes simple, and it is easier to find other equipment connected to the loop equipment.

8 is a flowchart of a method for generating a single line diagram of a distribution system according to an embodiment of the present invention.

Referring to FIG. 8, first, an entity including a facility symbol and a concentric circle surrounding the facility symbol is created for each facility of the power distribution facility. In this case, in the case of the n-circuit distribution facility, the size of the concentric circle of the distribution facility connected to the lower end of the n-circuit distribution facility is generated to be smaller than the size of the concentric circle of the entity representing the n-1 circuit distribution facility (S801).

Next, the objects are placed on the first layer. At this time, referring to the system diagram, in the case of interconnected facilities, the concentric circles of each entity are arranged to circumscribe (S802).

Next, referring to the system diagram, the second layer is output by connecting the facility symbols on the first layer according to the connection relationship between the facilities (S803).

Next, the third layer from which the concentric circles surrounding the facility symbols are removed from the second layer is output (S804).
