the graph database acquisition module is used for acquiring and storing power supply transformer information and power grid line information of a preset area in a graph database, taking the power supply transformer information as node data in the graph database, and taking the power grid line information as line data in the graph database;
the work order data acquisition module is used for acquiring work order data of business expansion installation applied by the power users in the preset area;
the first preset transformer set generation module is used for searching transformers meeting work order data in a preset distance range according to the work order data of business expansion installation applied by power users to obtain a first preset transformer set, if the first preset transformer set is an empty set, switching to the first preset transformer set generation module, and otherwise, switching to the second preset transformer set generation module;
the first preset transformer set generation module is updated and used for increasing the numerical value of the preset distance, further searching for transformers meeting the work order data and updating the first preset transformer set;
the second preset transformer set generation module is used for screening out transformers with available capacity and voltage levels meeting the requirement of users on application work order data to obtain a second preset transformer set, increasing the numerical value of a preset distance if the second preset transformer set is an empty set, and switching to the first preset transformer set generation module, or switching to a business expansion target transformer determination module;
and the business expansion target transformer determining module is used for respectively calculating the distance between each transformer in the second preset transformer set and the user installation address, and determining the transformer meeting the preset conditions as the business expansion target transformer.
8. A terminal, comprising: at least one processor, and a memory communicatively coupled to the at least one processor, wherein the memory stores instructions executable by the at least one processor to cause the at least one processor to perform the graph database-based power industry augmentation method of any of claims 1-6.
9. A computer-readable storage medium storing computer instructions for causing a computer to perform the graph database-based electric power industry installation method according to any one of claims 1 to 6.
