As shown in fig. 1 and 2, an embodiment of the topology identification method of the power distribution network based on the identifiable ID of the power line according to the present invention is shown.
The method of the embodiment comprises the following steps:
step 1, ID information of power line terminals connected with all power equipment in a low-voltage transformer area is obtained, and association relations exist among the power line terminals of the same power line.
Among the power line terminals of the same power line (power line in the same network), there is a fixed association relationship between the power line terminal (1 or more) as the power line inlet terminal and the power line terminal (1 or more) as the power line outlet terminal, that is, the same power line can be identified by the ID information, or referred to as the same network power line, and the power devices connected by the power line can be determined, and the connection relationship between the power devices can be determined. The same power line or the same network refers to power line terminals of power lines which are not electrically connected with each other through power equipment, and the power lines can be integrally formed or formed by electrically connecting multiple sections of power lines.
In the method of this embodiment, the power line terminals of the same power line (power line within the same network) have the same ID information, for example, the incoming line terminal(s) and outgoing line terminal(s) of the same power line have the same ID information. Specifically, as shown in fig. 2, the power line for connecting the power device QF0 and the power devices QF1, QF2 and QF3 is a power line or a power line of the same network, which has 1 incoming line terminal and 3 outgoing line terminals, and 4 terminals have the same ID information, which is T2.
As other embodiments, in the power line terminals of the same power line (power line in the same network), the ID information of the power line terminals as the power line terminals is the same, and there is a multiple relationship between the two (for example, the ID information of the power line terminals as the power line terminals is 1, the ID information of the power line terminals as the power line terminals is 2 times the former, the latter is 2 times), or the phase difference is a fixed number (for example, the ID information of the power line terminals as the power line terminals is 100, the ID information of the power line terminals as the power line terminals is 98, the latter is 2 less than the former), or the phase difference is a fixed number of bits (for example, the ID information of the power line terminals as the power line terminals is 100, the two are one bit different), and other various ways are not listed here.
As other embodiments, in the power line terminals of the same power line (power line in the same network), the ID information of the power line terminals as the power line terminals has the same first common value and respective characteristic values and each characteristic value is in an arithmetic progression, the general expression is a-B, the ID information of the power line terminals as the power line terminals has the same second common value and respective characteristic values, the general expression is C-D, the first common value and the second common value are different but there is a fixed functional relationship therebetween, that is, c=f (a); for example, if the first common value of the power line inlet terminal as the inlet terminal is 10000 and the respective characteristic values are in an arithmetic progression, the ID information of the power line inlet terminal as the inlet terminal is 10000-1, 10000-2 in order, and so on; the second common value of the power line inlet terminal as the outlet terminal is 20000, the ID information of the power line terminal as the outlet terminal is 20000-1, 20000-2 in order, and so on.

For example, the ID information includes 10 data bits, the last 6 data bits are taken as identification bits, and the power line terminals of the same identification bits are the same power line (power line in the same network).
Further, the ID information of the terminals of the different phase power lines is different; for example: the ID information can distinguish the power line terminals of the A, B, C, N phase power line. I.e. the ID information comprises information of the phase in which the power line terminal is located. For example, the ID information may include a plurality of data bits, where a number of the data bits indicate a phase pole where the power line is located, that is, the plurality of data bits of the ID information include phase pole data bits, for example, the first two data bits indicate a phase pole where the power line is located, and the first two data bits are identical, and of course, other data bits are different, at the power line terminals connected to the a-phase power line.
Preferably, the ID information is NFC tag information, that is, ID information that can be read by NFC communication.
And 2, obtaining the connection relation of each power device according to the ID information obtained in the step 1, and carding out the topological structure of the power devices in the low-voltage transformer area.
Preferably, at least one of the power devices in the low-voltage transformer area is a concentrator, the concentrator acquires the ID information of the power line terminal connected to each power device, records the device ID of the power device and the ID information of the power line terminal connected to the power device, obtains the device ID of the power device connected through the same power line (the power line in the same network) according to the association relationship between the ID information of the power line terminal, obtains the connection relationship of each power device in the low-voltage transformer area, and combs out the topology structure of the power device in the low-voltage transformer area. For example, as shown in fig. 2, the power devices storing the same ID information are connected, and specifically, the concentrator obtains its own device ID as CO, the ID information of the connected power line terminal as T1, the device ID of the obtained power device QF0 as QFO, the ID information of the connected power line terminal as T1, T2, the device ID of the obtained power device QF1 as QF1, the ID information of the connected power line terminal as T2, T3, the device ID of the obtained power device QF2 as QF2, and the ID information of the connected power line terminal as T2, T4.

The ID information acquired by the concentrator comprises the ID information of the power line terminal connected with the concentrator and the ID information of the power line terminal connected with other power equipment.
