Abstract With the constantly expanding of the power grid, the geographical wiring diagram of the power grid is becoming increasingly complex. Its drawing and maintenance are very difficult, gradually becoming a major difficulty in the operation and maintenance of power dispatch automation. This article introduces an automatic mapping method for power grid geographic wiring diagrams based on a panoramic model of the power grid, which integrates multiple technologies such as specifying the scope of power plants and stations, latitude and longitude positioning, T-line synchronization generation, and multi layer display. It is suitable for various levels and complexities of power grids. This method reliesg on the interval container model and introduces T-line synchronous generation technology, greatly improving the completeness of the mapping. According to the different voltage levels of power grid equipment, the introduction of multi layer technology enables the display of equipment with different voltage levels in geographical wiring diagrams, significantly enhancing the mapping effect. The mapping layout supports manual adjustment and is not automatically updated after model changes, effectively compensating for the shortcomings of automatic mapping in local processing. This method has been applied for the first time in the dispatch control system of a smart grid in a certain region. Practice proves that this method significantly reduces the labor costs incurred in the process of drawing and updating the geographic wiring diagram of the power grid, and has broad prospects for promotion.
