Abstract

The embodiment of the invention discloses a low-voltage transformer area topology identification method, device and equipment. The method comprises the steps: a processing terminal generates a transformer area power line topological graph according to the logic relation of the transformer area power line topology, and transmits the transformer area power line topological graph to a display terminal for display through a method of improving the link application bandwidth. According to the embodiment of the invention, the method effectively avoids the defects in the prior art that the bandwidthused by the processing terminal for transmitting the information of the power line topological graph of the transformer area is reduced when the processing terminal is located under the condition thatthe interference on the link is large, and the application effect of the link is not promoted.

Description

technical field [0001] The invention relates to the technical field of low-voltage power distribution, in particular to a low-voltage station area topology identification method, device and equipment. Background technique [0002] The distribution station area usually refers to the power supply range or area of ​​a transformer in the power system. As a power supply area from a single distribution transformer to users, the distribution station area can realize power distribution, continuously provide power to users, and ensure the normal power consumption of an area. The automatic identification of the topological relationship of the low-voltage line in the distribution station area is essentially to reliably obtain the connection relationship between the electrical equipment directly connected to the low-voltage line and the low-voltage outlet cabinet in the station area. [0003] In order to efficiently and reliably obtain the power line topology of the low-voltage station...

Problems solved by technology

[0004] With the mature application of LTE communication now, the current processing terminal generally adopts a controller connected to an LTE module, and the display terminal is a PC set in the LTE network, so that it can pass through the LTE terminal of the processing terminal. The module transmits the information of the topological map of the power line in the station area to the display terminal of the PC set in the LTE network for display. At present, the standby mode of the LTE module of the overall processing terminal is often when the processing terminal and the display terminal are monitored. When there is no information transmission of the topological map of the power line in the station area, the LTE module of the processing terminal is in the standby mode, that is, the value of the previously set identification variable in the memory of the controller of the processing terminal will be set to 16 Hexadecimal number 0XFF, until the processing terminal has other power line topology map information to be received, then set the value of the pre-set identification variable in the memory of the controller of the processing terminal to the hexadecimal number 0XEE , so that the LTE module is activated, so that it is in the operating state; when the processing terminal is activated, it needs to perform link monitoring again. If the link between the processing terminal and the display terminal is occupied, the processing terminal has to wait for a while After an interval, wait for the link between the processing terminal and the display terminal to be idle, and then transmit the information of the power line topology map of the station area; The information of the topological map of the power line in the station area monitored by the idle road must be transmitted according to the low bandwidth of QPSK modulation, which reduces the bandwidth used by the processing terminal to transmit the information of the topological map of the power line in the station area when the link is subject to large interference conditions. transmission, which is not conducive to the effect of link utilization
