[0040] As shown in the figure, in an embodiment of the present application, a feeder power supply section automatic mapping display method is provided, comprising the following steps: Figure 1

[0041] Step 101, distributed topology analysis is performed on the main grid model, the medium voltage model of the distribution network and the low voltage model of the distribution network, to obtain the main-distribution boundary mapping relationship and the medium-low voltage boundary mapping relationship of the distribution network, specifically: main-distribution boundary analysis is performed on the main grid model and the medium voltage model of the distribution network, to obtain the corresponding main-distribution boundary mapping relationship; medium-low boundary analysis is performed on the medium voltage model of the distribution network and the low voltage model of the distribution network, to obtain the corresponding medium-low voltage boundary mapping relationship of the distribution network;

[0043] Step 102, receiving selection of the feeder in the main-distribution integrated model, performing power supply section splitting on the grid frame of the selected feeder, to obtain a plurality of corresponding power supply sections;

[0044] Step 103, performing distribution network connection relationship analysis on each power supply section according to the devices included in each power supply section, to generate the power supply range and upstream and downstream relationship corresponding to each power supply section;

[0045] Step 104, mapping display of the power supply range and upstream and downstream relationship corresponding to each power supply section. ​

[0046] Specifically, the existing main distribution splicing generally adopts a main network model and a distribution network medium and low voltage model to realize terminal welding of the main distribution, distribution network medium and low voltage, and the hard welding mode is used every time, and the main distribution integrated topology is used every time. The existing model processing method is that the main network and the distribution network medium and low voltage topology model are all resident in the memory, and no matter which link changes, the splicing, extraction and loading of the memory need to be re-performed. The system occupies high resources and has low updating efficiency. Each search is based on the main distribution full amount to complete the topology, and when the main distribution model is large, the search efficiency is low.

[0047] Preferably, the distribution network model comprises a distribution network medium voltage model and a distribution network low voltage model. The application adopts a distributed topology analysis technology to analyze the main distribution boundary of the main network model and the distribution network medium voltage model, to obtain the corresponding main distribution boundary mapping relationship; analyze the medium and low boundary of the distribution network medium voltage model and the distribution network low voltage model, to obtain the corresponding distribution network medium and low voltage boundary mapping relationship; and splice the main distribution according to the main network model, the distribution network medium voltage model, the distribution network low voltage model, the main distribution boundary mapping relationship and the distribution network medium and low voltage boundary mapping relationship; the application only records the boundary position between the main distribution, the distribution network medium voltage and the distribution network low voltage, so as to obtain the main distribution integrated model of the main network and the distribution network. The soft welding model processing method is simpler and faster.

[0048] The application is aimed at the main distribution network model, splices the main network model, the distribution network medium voltage model and the distribution network low voltage model, and integrates the main distribution integrated model. The main network model and the distribution network model are spliced according to the subordinate relationship of the power supply bureau, the power supply station, the substation, the feeder group and the tie switch, the main distribution integrated model of the navigation tree containing the power supply bureau, the power supply station, the substation, the feeder group and the tie switch is constructed and displayed. The power supply bureau, the power supply station, the substation, the feeder group and the tie switch are the actual subordinate relationship of the main distribution network, and how many power supply stations are under a certain power supply bureau, how many substations are under a certain power supply station, how many feeder groups are associated with a certain substation, and how many switches are on a certain feeder group, which are determined according to the power grid architecture of the main distribution network.

[0049] Then, receiving selection of a feeder in the main distribution integrated model, performing power supply section splitting on a network frame of the selected feeder to obtain a corresponding plurality of power supply sections. Specifically, a topology analysis can be performed on an xml model file of the selected feeder to generate a basic feeder topology tree corresponding to the selected feeder, with a substation outlet switch as a root node and distribution transformers and tie switches as leaf nodes. That is, all devices on the selected feeder are traversed according to electrical connection relationships, including various types of switches. Thus, the process of generating a topology tree for the selected feeder is as follows: without considering the state of a switch / switching device, traversing with the tie switch or a specified switch as a boundary to generate a topology tree containing busbars, switches, switching devices, loads, distribution transformers and the like; in the topology process, a substation outlet busbar is a root node and distribution transformers and tie switches are leaf nodes.

[0050] When performing second-level, minute-level and hour-level restoration capability calculation of a distribution network, the network frame of a feeder needs to be sectionally split according to different switch types. The present application performs power supply section splitting on the network frame of a selected feeder according to different switch types to obtain a plurality of power supply sections corresponding to the selected feeder under different switch types.

[0051] Then, for each power supply section, the present application further performs upstream power supply topology path tracking analysis on each voltage grade switch device in each power supply section to visualize and draw an upstream power supply path; downstream power supply lines and device data can also be analyzed; the corresponding upstream and downstream relationships of each power supply section can be generated. The present application also analyzes the power supply range of the area surrounded by the switches in each power supply section.

[0052] Finally, the power supply range and upstream and downstream relationships corresponding to each power supply section are displayed in a graph. The present application realizes longitudinal and lateral perspective analysis of a feeder by performing integrated analysis on main and distribution network models, realizes automatic, real-time, fast and rich drawing of a feeder power supply section graph, and further displays operation information and data of various switch devices, bringing great convenience. The system automatically obtains graph model data of a dispatching master station and a GIS system to quickly generate various topology graphs, replacing manual analysis.

[0053] Existing main distribution splicing generally uses a main network model and a distribution network medium and low voltage model to realize terminal welding of the main distribution and distribution network medium and low voltage. This hard welding method uses a main distribution integrated topology each time. The existing model processing method has the main network and distribution network medium and low voltage topology models all residing in the memory, and regardless of which link has a topology change, the splicing, extraction and loading into the memory need to be performed again. The system occupies high resources and has low update efficiency. Each search is based on the main distribution full amount to complete topology, and when the main distribution model is large, the search efficiency is low.

[0054] Preferably, the distribution network model comprises a distribution network medium voltage model and a distribution network low voltage model. The application further uses a distributed topology analysis technique to analyze the main network model and the distribution network medium voltage model to obtain a main-distribution boundary mapping relationship; analyze the distribution network medium voltage model and the distribution network low voltage model to obtain a distribution network medium-low voltage boundary mapping relationship; and splice the main-distribution according to the main network model, the distribution network medium voltage model, the distribution network low voltage model, the main-distribution boundary mapping relationship, and the distribution network medium-low voltage boundary mapping relationship. The application only records the boundary positions among the main-distribution, the distribution network medium voltage, and the distribution network low voltage, thereby obtaining a main-distribution integrated model of the main network and the distribution network. This soft welding model processing method is simpler and faster.

[0056] The power supply section splitting of the grid frame of the selected feeder according to different switch types, and the obtaining of the corresponding multiple power supply sections of the selected feeder in the case of different switch types.

[0057] Specifically, the multiple restoration time efficiencies (second level, minute level, and hour level) of the main-distribution network are calculated, that is, when the power distribution network second level, minute level, or hour level restoration capability is calculated, the selected feeder is split into multiple power supply sections according to the automation switch, the tie switch, and the sectionalizing switch. In the case of second level, minute level, or hour level, the multiple restoration capability power supply sections split from the same feeder are different.

[0058] In one embodiment, the distribution network connection relationship analysis of each power supply section according to the devices included in each power supply section, and the generation of the power supply range and the upstream and downstream relationship of each power supply section, comprise:

[0059] The distribution network connection relationship analysis of all devices included in each power supply section, the analysis of the power supply devices in the range of all devices, and the determination of the corresponding power supply range according to all power supply devices.

[0060] The distribution network connection relationship analysis of all devices included in each power supply section, the tracking of the upstream power supply path of each device to the power supply path to the outgoing switch, and the tracking of the downstream power supply path of each device.

[0061] Specifically, the application can track and analyze the upstream power supply path of each voltage level switch device in each power supply section according to the power grid topology of the main distribution network through distribution network connection relationship analysis, and can also analyze the downstream power supply lines and device data of each voltage level switch device in each power supply section. The application can also analyze the power supply range of the area surrounded by all switch devices in each section according to the power grid topology of the main distribution network through distribution network connection relationship analysis.

[0062] In one embodiment, the mapping display of the corresponding power supply range and upstream and downstream relationship of each power supply section comprises:

[0063] According to the corresponding power supply range of each power supply section, a map is drawn and displayed on the main-distribution integrated model.

[0064] Specifically, according to the corresponding power supply range of each power supply section, a map can be drawn and displayed. Preferably, the corresponding power supply range of each power supply section can be colored using different colors. The upstream and downstream power supply paths of each power supply section can also be colored using different colors.
