Problems solved by technology
[0004] After the above-mentioned method of constructing the power grid topology model determines the starting node device, it needs to search for the target node devices one by one along the direction of multiple node devices connected to the starting node device. Usually, it needs to go through multiple cycles to realize the power grid topology model construction, reducing the construction efficiency
Moreover, the power grid topology model established in this way may only be a local topology structure, and cannot draw a topology map of the entire network.

The embodiment of the invention discloses a method for constructing a topology model of a power grid. The method comprises the steps of connecting a power equipment database comprising power equipment nodes and linkage points; selecting one power equipment node as a father node, and searching a linkage point which an endpoint of the father node belongs to; judging whether the linkage point includes other endpoints, if so, searching the power equipment nodes respectively corresponding to other endpoints according to each of other endpoints, taking the searched power equipment nodes as child nodes of the father node, and circularly executing a step of searching the linkage point by taking each child node as the new father node; and otherwise, establishing the topology model of the power grid according to the father node and the child nodes. The embodiment provided by the invention further discloses a device for constructing the topology model of the power grid. According to the embodiment of the invention, the topology model of the power grid is constructed in a form of a tree-like structure, a relation path of each node is completely recorded, and the efficiency for constructing the topology model of the power grid is improved.
Description
technical field [0001] The present application relates to the technical field of electric power systems, in particular to a method for constructing a power grid topology model and a corresponding device. Background technique [0002] With the development and promotion of the smart grid, more and more power basic applications rely on the grid topology model, which reflects the topology relationship among many power devices in the actual grid. Common applications based on the power grid topology model include: determining faulty equipment and fault points in the power system through the power grid topology model, and the scope of influence of planned power outages. These applications are conducive to improving the intelligence level of the power system and improving the reliability of power supply. It can be seen that the construction of the power grid topology model plays an important role in the application process of the power system. [0003] At present, in the field of p...
