Referring to FIG. 3, when the switchboard panel 10 is installed, breakers may be sequentially installed in the switchboard panel 10.

For example, the first circuit breaker CB1 is installed at the first line PL1 that is the uppermost line, and the second circuit breaker CB2 and the third circuit breaker CB3 are respectively provided at the second line PL2 and the third line PL3. Can be installed. The first circuit breaker CB1 may correspond to an ACB, and the second circuit breaker CB2 and the third circuit breaker CB3 may correspond to an MCCB, but are not necessarily the same.

When the first circuit breaker CB1 to the third circuit breaker CB3 is installed, the PLC module provided in each of the first circuit breaker CB1 to the third circuit breaker CB3 is connected to the first circuit breaker CB1 to the third circuit breaker through lines. A power line communication network between the CB3s can be formed.

When the power line communication network is formed, the PLC module of the second circuit breaker CB2 may determine that the parent circuit breaker of the second circuit breaker CB2 is the first circuit breaker CB1 based on the grid relationship of the lines. The PLC module of the third breaker CB3 may also confirm that the parent breaker of the third breaker CB3 is the first breaker CB1 in a similar manner. Based on the check result, the PLC module of the second breaker CB2 includes a first identification information ID of the second breaker CB2 and information about the parent breaker CB1 of the second breaker CB2.

Referring to FIG. 5, the gateway 14 may receive system information INFO1 to INFO7 of each of the breakers from the first breaker CB1 corresponding to the highest breaker. In this case, since only the first branch information INFO1 to the seventh branch information INFO7 can generate a tree diagram for the first breaker CB1 to the eighth breaker CB8, the branch for the first breaker CB1 itself. Information may not be included. However, according to an embodiment, the gateway 14 may also receive system information on the first breaker CB1.

The gateway 14 may transmit the received system information INFO1 to INFO7 to the data logger 20. The data logger 20 may transmit system information INFO1 to INFO7 received from the gateway 14 to the server 30. According to an embodiment, when the data logger 20 directly generates the schematics of the breakers CB1 to CB8, the data logger 20 does not transmit the received system information INFO1 to INFO7 to the server 30. In addition, the generated schematic may be transmitted to the server 30.

Referring to FIG. 6, the server 30 may generate a schematic diagram ANC_DIAGRAM of the breakers CB1 to CB8 based on the received systematic information INFO1 to INFO7. In FIG. 6, the server 30 generates the schematic diagram ANC_DIAGRAM, but as described above, the data logger 20 may generate the schematic diagram ANC_DIAGRAM.

The server 30 may analyze the system relationship of the breakers CB1 to CB8 from the received system information INFO1 to INFO7, and generate the system diagram ANC_DIAGRAM based on the analysis result.

Accordingly, the server 30 may generate the system diagram ANC_DIAGRAM in which the breakers CB1 to CB8 illustrated in FIG. 2 show the same system relationship as the system relationship.

That is, according to the exemplary embodiment shown in FIGS. 2 to 6, the system analysis system automatically generates a schematic diagram of the circuit breakers 11 by using power line communication, thereby preventing time consumption or an error caused by manual generation of the schematic diagram. You can prevent it.

FIG. 7 is a flowchart for describing an embodiment in which the system analysis system provides a guide for changing a circuit breaker arrangement based on a circuit breaker diagram generated using power line communication, and FIG. 8 is an embodiment illustrated in FIG. 7. Is a view showing an example of a circuit breaker arrangement change guide provided according to.

In the installation of the breakers 11, the manager may determine a line to be arranged based on the allowable current of each of the breakers 11. For example, the manager may place a circuit breaker having a relatively high allowable current on the upper line and a circuit breaker having a relatively low allowable current on the lower line.

However, due to the mistake of the administrator or the complexity of the line, a circuit breaker with a low allowable current may be disposed on the upper line. In this case, a breaker disposed in the current flowing in the upper line is frequently operated, which may cause a problem that the current is not smoothly supplied to the load.

Referring to FIG. 7 based on this, the system analysis system may generate a schematic diagram of the breakers 11 included in the switchboard panel 10 (S700). As described above with reference to FIGS. 3 to 6, the data logger 20 or the server 30 may generate a schematic diagram ANC_DIAGRAM for the breakers 11.

The system analysis system detects a lower circuit breaker having an allowable current greater than the allowable current of the upper circuit breaker based on the generated circuit diagram (S710), and based on the detection result, provides a breaker arrangement change guide. It may be (S720).

In this regard, referring to FIG. 8, the server 30 (or the data logger 20) may allow the current of the parent breaker based on the generated circuit diagram ANC_DIAGRAM and allowable current information of each of the breakers CB1 to CB8. Progeny breakers with larger allowable currents can be detected. To this end, the server 30 may include a memory (not shown) in which allowable current information of each of the breakers CB1 to CB8 is stored.

For example, when the allowable current of the third breaker CB3 is 60 A and the allowable current of the eighth breaker CB8 corresponding to the child breaker of the third breaker CB3 is 100 A, the server 30 may use the third breaker ( The arrangement change guide CHG_GUIDE may be generated to guide the positions of the CB3) and the eighth breaker CB8 to be changed.

The server 30 may transmit the generated batch change guide CHG_GUIDE to the gateway 14. The gateway 14 may display the layout change guide CHG_GUIDE through the HMI 40. According to an embodiment, the server 30 may transmit the layout change guide CHG_GUIDE to a terminal (not shown) of the manager. The manager may change the arrangement of the third breaker CB3 and the eighth breaker CB8 based on the arrangement change guide CHG_GUIDE.

That is, the system analysis system allows the circuit breakers to be optimally arranged based on the allowable current of the breakers, so that when the circuit breaker having a relatively low allowable current is placed on the upper line, the line is frequently cut off to smoothly supply current to the load. This can effectively prevent problems that do not occur.
