Power grid monitoring method for automatically generating three-dimensional hierarchical structure based on geographic information

Abstract

The invention relates to a power grid monitoring method for automatically generating a three-dimensional hierarchical structure based on geographic information. The method is technically characterizedin that regional substation automatic virtual modeling is performed according to substation geographic information, a substation model and a substation internal transformer model; according to an in-station primary connection diagram and an inter-station tidal current diagram, and a data model and topological data which are required for generating a three-dimensional hierarchical region model areacquired; a power grid is layered according to voltage levels; master device transformers of a simulated substation in the three-dimensional model are connected hierarchically according to the obtained topological data; hierarchical display of the power grid is performed; and real-time data of connection line tidal currents, substation heavy overloads and real-time meteorology is acquired respectively, and a real-time monitoring function on the power grid is achieved. According to the method, by performing automatic three-dimensional hierarchical modeling on the power grid, a simulated three-dimensional world which can be used for monitoring the power grid in real time within a scheduling range is formed; and meanwhile, through connecting display of the real-time data of the power grid, centralized monitoring of regional master devices is more efficient and rapid.

Description

technical field

[0001] The invention belongs to the technical field of power system information, in particular to a power grid monitoring method for automatically generating a three-dimensional layered structure based on geographical information. Background technique

[0002] With the advancement of the construction of the big data system of the power grid and the construction of the State Grid Cloud Database, the data of the power grid is more concentrated, fuller, and richer. The power grid can more accurately analyze the current operation of substations and regional power grids through multi-source data. At present, grid data is usually displayed in text and tables, which is not intuitive and difficult to understand, especially when it involves the combination of geographic information and grid data, such as when substations and lines change, how to visualize Displaying and monitoring is an urgent problem to be solved at present.
